Mongolia's diplomatic engagement with Central Asia and the Caucasus marks a pivotal evolution of its "third neighbor" strategy, aimed at strengthening partnerships beyond its traditional ties with Russia and China. This strategic shift has gained urgency in light of changing regional dynamics within Greater Central Asia. Since 2020, Mongolia has intensified its diplomatic activities, exemplified by presidential visits to Uzbekistan and Kazakhstan in 2024. Economic interactions, while still modest, show promising growth, notably in trade with Kazakhstan, Kyrgyzstan, and Uzbekistan, where exports have notably increased. These developments align with broader regional trends towards greater independence from Russia and China, as Central Asian countries seek to establish cooperative mechanisms. Ultimately, Mongolia's westward pivot not only enhances its sovereignty but positions it as a crucial player in promoting regional stability and cooperation in the evolving Eurasian geopolitical landscape.

BACKGROUND: Mongolia's diplomatic engagement with Central Asia and the Caucasus represents the latest evolution of its third neighbor strategy—a long-standing policy aimed at cultivating partnerships beyond Russia and China to enhance Mongolia’s sovereignty. This westward pivot has emerged as a strategic necessity for Mongolia, particularly as regional dynamics across Greater Central Asia undergo significant transformation.

Mongolia's diplomatic activity with Central Asia has accelerated markedly since 2020. High-level visits, previously sporadic, have become increasingly frequent and substantive. President Ukhnaagiin Khurelsukh's recent state visits to Uzbekistan and Kazakhstan in 2024 resulted in numerous bilateral agreements, bolstering cooperation in trade, transport, and cultural exchange. The visit to Uzbekistan yielded 14 bilateral agreements and the inauguration of Mongolia's Embassy in Tashkent. Similarly, the Kazakhstan visit established a formal strategic partnership. Mongolia's diplomatic outreach extended to Turkmenistan, marking the first bilateral presidential visits since diplomatic relations began in 1992, and to Kyrgyzstan, where bilateral relations have steadily improved following President Sadyr Japarov's 2023 visit to Mongolia and the opening of the Kyrgyz Embassy in Ulaanbaatar.

Economic engagement, while still modest, demonstrates upward momentum. Trade with Kazakhstan has reached approximately $150 million annually, with Mongolian exports of horse meat growing from $2.9 million in 2017 to $8.3 million in 2022. Kazakhstan's exports to Mongolia, primarily industrial and consumer goods, increased from approximately $72.9 million to $93 million during the same period. Mongolia's trade with Kyrgyzstan doubled from about $2 million in 2017 to over $5 million by 2022, driven by re-exported used cars and consumer goods. Trade with Uzbekistan grew dramatically from under $1 million in 2017 to nearly $10 million by 2022, focused on meat exports and Uzbek fertilizers. Meanwhile, trade with Turkmenistan and Tajikistan remains negligible. For Mongolia, with $20 billion GDP and over 90% of export goes to China, this is a significant development.

Mongolia's engagement with the Caucasus remains nascent but shows promising signs. High-level diplomatic exchanges include former President Tsakhiagiin Elbegdorj's official visits to Armenia in 2015 and Georgia in 2016, enhancing trade and cultural ties. Azerbaijan received a working visit from former President Khaltmaagiin Battulga in 2018, exploring collaborations in energy and investment. While trade volumes remain limited, recent growth is evident, particularly with Azerbaijan, where exports surged to approximately $1.6 million in 2024, primarily in livestock products.

These developments have occurred against the backdrop of emerging region-wide structures in Greater Central Asia, as countries seek to develop collective mechanisms for cooperation outside the frameworks dominated by Russia and China. Mongolia's engagement with these structures aligns with the broader regional trend toward developing greater agency and connectivity across Central Asia and the Caucasus.

IMPLICATIONS: Mongolia's deepening engagement with Central Asia and the Caucasus presents crucial economic and strategic diversification opportunities. Enhanced diplomatic and economic ties provide Mongolia with a hedge against over-reliance on China, currently its dominant trading partner, and alternative options given restrictive Western sanctions against Russia. The geographic and economic profiles of Kazakhstan and Uzbekistan, with their combined population of approximately 56 million, offer ample market opportunities for Mongolia.

Politically, Mongolia's democratic governance, a distinctive feature in the region, offers a stable and transparent framework for engagement. This reliability in governance and commitment to international norms facilitates more predictable and trustworthy partnerships in areas crucial for regional development, such as trade facilitation, infrastructure investment, and the establishment of robust legal frameworks for transport corridors. This unique identity enhances Mongolia's value to Western partners and provides a practical model for how democratic principles can support economic and strategic cooperation in a challenging geopolitical landscape. Furthermore, Mongolia's active participation in cultural events like the World Nomad Games reinforces shared heritage with Central Asian states, promoting a regional identity that bridges East and West.

The integration into regional mechanisms offers Mongolia access to emerging transport corridors, particularly the "Middle Corridor" that connects Asia to Europe without crossing Russian territory. This connectivity could mitigate Mongolia's landlocked status and provide more direct routes to global markets. The successful development of these corridors would significantly reduce Mongolia's vulnerability to geopolitical pressures from its immediate neighbors.

Central Asian and Caucasus countries benefit from Mongolia's outreach through expanded diplomatic networks and opportunities for collaborative initiatives in transport, energy, agriculture, environment and mining. Mongolia's strategic neutrality and pragmatic foreign policy approach are viewed positively in the region, enabling enhanced collaboration without triggering sensitive geopolitical responses from Russia and China.

The burgeoning regional integration subtly shifts dynamics for Russia and China. Although both powers are likely to tolerate Mongolia's increased engagement due to its non-military, primarily economic and diplomatic nature, deeper regional cooperation could eventually dilute their influence. Increased regional activity that transcends Russian and Chinese dominance, along with coordinated economic policies, could reduce regional dependency on Moscow and Beijing, leading to cautious observation from both capitals.

China's Belt and Road Initiative has significantly shaped regional infrastructure development, but Mongolia's growing ties with Central Asia introduce an alternative approach to connectivity that might circumvent Beijing's leverage. Similarly, Russia's attempts to maintain regional influence through the Eurasian Economic Union face challenges as Mongolia and Central Asian states pursue more diverse partnerships. This diversification of regional relationships represents a gradual but significant shift in the geopolitical landscape.

Mongolia's third neighbors (the U.S., EU, India, Japan, South Korea, and Turkiye) view this westward pivot positively. Strengthening Mongolia's regional ties aligns with broader Western strategic goals, including promoting stability and sovereignty in Central Asia. High-profile European visits to Mongolia, followed by tours to Central Asia (e.g., French President Emmanuel Macron’s and former UK Foreign Secretary David Cameron’s multi-leg visits), illustrate growing interest in Mongolia's bridging role. These engagements allow Western countries to enhance their regional presence without being perceived as exclusively engaging with authoritarian regimes.

The U.S., which has traditionally engaged Central Asia through the C5+1 format, could consider integrating Mongolia into this dialogue, potentially transforming it into a C6+1 arrangement. As outlined in the American Foreign Policy Council's (AFPC) April 2025 report, such integration would better reflect Mongolia's shared strategic and economic challenges with the region, particularly in critical minerals essential to global supply chains. Similarly, Japan and South Korea recognize Mongolia's potential as a gateway to continental Asia, leveraging soft power and economic investments to enhance regional integration.

CONCLUSIONS: Mongolia's pivot toward Central Asia and the Caucasus is driven by strategic necessity and presents significant opportunities for regional integration. The past years' diplomatic and economic initiatives signal genuine, albeit incremental, progress. Although concrete outcomes remain limited, the diplomatic momentum could lead to substantive cooperation in trade, transport, and infrastructure.

For Mongolia, regional integration serves as a diplomatic insurance policy, enhancing strategic autonomy amid geopolitical uncertainty. The pragmatic approach toward bilateral and multilateral cooperation mitigates potential pressure from Russia and China while strengthening ties with Western democracies. The development of region-wide structures that exclude external powers could create space for greater collective agency among the states of Greater Central Asia, including Mongolia.

Mongolia's westward orientation strategically positions it as a significant actor capable of bridging regional divides, promoting economic cooperation, and advocating democratic governance. As suggested in the AFPC’s strategy document, the emergence of a more integrated Greater Central Asia, including Mongolia, could serve as a stabilizing force across the region. Whether this evolves into more tangible regional integration or remains predominantly at the diplomatic level will significantly impact Mongolia's role in the evolving Eurasian geopolitical landscape.

The increasing American strategic interest in Greater Central Asia, with its emphasis on developing exclusive region-wide structures and enhancing connectivity, aligns with Mongolia's objectives. This convergence of interests offers Mongolia an opportunity to reinforce its sovereignty through regional integration while contributing to a more balanced regional order less dominated by Russia and China. In this evolving framework, Mongolia's distinctive political identity and strategic positioning could turn the country into an indispensable player.

Azerbaijani President Ilham Aliyev’s April 2025 state visit to China, culminating in the signing of a Comprehensive Strategic Partnership, marks a significant elevation in bilateral relations. The agreement is more than a symbolic gesture: it reflects a strategic convergence across infrastructure, energy, and digital development. It also signals a re-balancing of power in the South Caucasus in response to Western inertia. As China consolidates its position, the question is no longer whether the West leads but whether it has already surrendered the initiative.

BACKGROUND: The Second Karabakh War of 2020 abruptly exposed the obsolescence of entrenched diplomatic frameworks in the South Caucasus, most notably the OSCE Minsk Group. The November 2020 Trilateral Statement that ended the fighting, brokered under Russia’s aegis, signified an incipient restructuring of regional dynamics. Russia positioned itself as the nominal guarantor of stability, installing a contingent of so-called peacekeepers on Azerbaijani territory. Yet this maneuver, driven by residual influence and opportunistic calculus, underscored Moscow’s determination to preserve a semblance of relevance amid shifting fault lines.

While Russia acted following long-established and well-defined interests, the U.S. and the EU hesitated. The initiatives introduced by Western actors, preoccupied with internal crises and other entanglements, lacked coherence, confidence, and strategic vision. The mediation efforts were fragmented and the summits were ad hoc. As a result, the promising diplomatic overtures failed to generate substantive traction. The reactive nature of Western engagement post-2020 contrasts starkly with the proactive moves of regional and other stakeholders having more immediate stakes in the evolving South Caucasus order.

Turkey’s deepening military partnership with Azerbaijan, formalized through the Shusha Declaration of 2021, epitomized pragmatic alignment. Kazakhstan, seizing the moment, accelerated its integration into the emergent Middle Corridor, bolstering East-West logistics networks through the Caspian basin. Concurrently, Gulf states capitalized on Azerbaijan’s post-war stabilization by channeling substantial investments into renewable energy infrastructure, particularly solar and wind projects in the liberated territories. These tangible gestures did not just reflect geoeconomic calculations but represented a recognition of the region’s latent economic potential.

In this context, China modified its traditionally cautious posture in the South Caucasus. Historically deferential to Russia’s informal sphere of influence, Beijing began to reassess the region’s strategic significance following the full-scale Russian invasion of Ukraine in February 2022. The resulting destabilization of Eurasian corridors, compounded by Western sanctions and the geopolitical weaponization of supply chains, propelled the South Caucasus from peripheral concern to a central axis in China’s connectivity strategy. This shift was not reflexive or opportunistic. Rather, it reflected China’s measured strategic assessment of the structural transformations in the architecture of Eurasian trade.

By 2022, the foundations for a deepening Sino-Azerbaijani partnership had been firmly established. The signing of a joint declaration on strategic partnership at the Shanghai Cooperation Organization summit in July 2024 signaled a decisive commitment to broaden bilateral economic ties. The two countries’ trade in 2024 was over 20 percent above its 2023 level, reaching nearly US$ 3.74 billion. Chinese enterprises expanded into sectors previously peripheral to their Eurasian ambitions: telecommunications, green energy, and transport logistics. President Ilham Aliyev’s state visit to Beijing in April 2025 did not initiate this trend but rather consolidated it. The Comprehensive Strategic Partnership (CSP) agreement was the logical culmination of sustained and deliberate moves that anchored Azerbaijan’s strategic realignment toward the East.

IMPLICATIONS: The realignment is not mere economic opportunism. Rather, it signals a deeper geopolitical evolution driven by the inadequacy of Western engagement and the region’s preparedness to respond to actors willing to match rhetoric with decisive action. The failure of Western policy is not just about inattentiveness, but also about an inability to grasp the interplay between regional agency, emerging connectivity frameworks, and the geopolitical vacuum created by Russia’s shifting posture. In this unfolding dynamic, Azerbaijan has moved beyond waiting for Western recognition or support. It has instead begun to assert its own role within a rapidly realigning Eurasian order.

For China, Azerbaijan serves as a gateway not only to Europe through the Middle Corridor but also toward the Middle East, reinforcing China’s broader trade architecture and strategic depth in the region. The CSP is not a symbolic gesture. Its scope is broad and consequential, encompassing coordinated industrial development, infrastructure harmonization, technology transfer, and streamlined customs protocols. These measures are underpinned by capital investments and long-term industrial partnerships. 

For Azerbaijan, the CSP consolidates a deliberate move to attenuate traditional dependencies on Western and Russian interlocutors. It embodies Azerbaijan’s long-articulated aspirations for economic diversification, substantiated now by tangible capital flows and operational partnerships. The CSP’s provisions span petrochemicals, metallurgy, mechanical engineering, and renewables. Agreements on aerospace and intellectual property signal a strategic depth, eschewing transactional engagement in favor of embedded, systemic collaboration. 

The transport dimension alone is reshaping regional dynamics. The Middle Corridor, stretching from China through Kazakhstan, the Caspian basin, and into the South Caucasus and Europe, has demonstrated rapid growth. While still smaller in scale than northern routes traversing Russia, its year-on-year expansion has been notable. A trilateral joint venture among Kazakhstan, Azerbaijan, and Georgia’s rail operators is actively synchronizing digital customs tracking and reducing delivery times to enhance competitiveness.

The Port of Alat, central to Azerbaijan’s maritime logistics, has already undergone substantial upgrades. Cross-border road transport agreements and operational protocols with China, concluded in 2024 and 2025, are streamlining east–west trade flows. China’s formal recognition of Azerbaijan as a "central transit node" underscores the strategic weight of this integration.

The significance of the CSP extends beyond ports and pipelines. Digital infrastructure has emerged as a foundational pillar. Huawei and ZTE, longstanding presences in the region, have solidified their positions through new agreements establishing joint research centers, expanding data infrastructure, and modernizing e-government frameworks. These initiatives are embedding Chinese technological standards into the South Caucasus and positioning Baku as a nascent digital hub.

Energy collaboration has similarly accelerated. China’s Universal Energy is backing the Gobustan solar project, with further discussions ongoing over potential wind energy developments along the Caspian coast. These initiatives are paralleled by an expansion of Chinese soft power, from Confucius Institutes to cultural exchanges and educational programs.

Azerbaijan has not “abandoned” the West. The reality is starker: the West has failed to keep pace with Azerbaijan’s evolving strategic calculus. President Aliyev’s visit to Beijing and the CSP with China are less an embrace of Beijing than a commentary on the chronic insufficiencies of Western engagement. For years, Baku signaled openness to deeper commercial ties, infrastructure investments, and a balanced diplomatic posture. What it often received were half-measures, symbolic gestures, and ideological critiques. 

The waning of Western diplomatic leverage in the South Caucasus is not a sudden anomaly. It is the cumulative outcome of incremental miscalculations, fragmentary approaches, and the persistent failure to integrate regional realities into a coherent strategic vision. The 2020 Second Karabakh War marked a decisive inflection point. Azerbaijan’s reintegration of its formerly occupied territories exposed the impotence of frameworks long regarded as the bedrock of resolution efforts. The abrupt reassertion of Azerbaijani territorial sovereignty in 2020, and its completion in 2023, underscored the extent to which Western actors had become disconnected from the region’s evolving dynamics.

Europe’s Global Gateway initiative, though nominally prioritizing the Middle Corridor, remains hesitant and underfunded. The U.S., preoccupied with broader geopolitical contests, has failed to sustain a coherent South Caucasus policy. When attention does surface, it is often filtered through domestic advocacy agendas misaligned with both regional stability and U.S. strategic interests. Thus, under the influence of domestic lobbies, two of the Biden administration’s last acts were to decline to waive Section 907 of the Freedom Support Act, which bans direct assistance to the Azerbaijani government, and to sign a bilateral strategic partnership charter with the Armenian government.

CONCLUSIONS: The South Caucasus has shifted from constituting a peripheral zone to a strategic nexus. Capital and influence from East Asia, Central Asia, and the Middle East are converging upon the region. Turkey, Kazakhstan, and the Gulf states have become active participants in this evolving matrix. Azerbaijan, far from merely serving as a bridge, has assumed the role of architect and builder of new routes. Aliyev’s visit to Beijing is emblematic of this shift. Baku no longer waits for external recognition; it engineers its own relevance. 

The West must recognize this not as a defection, but as an adaptation to opportunity over nostalgia. The coming months will be decisive. If the West wishes to remain a meaningful player, it must replace rhetorical overtures with substantive commitments: joint infrastructure ventures, credible support for energy transition, and diplomatic engagement rooted in regional realities rather than encumbered by historical preoccupations.

Azerbaijan’s choice is not between China and the West, but between agency and irrelevance. It has already chosen. The question now is whether the West retains both the capacity—and the will—to respond.

Since Donald Trump’s return to office, Washington has initiated high-level negotiations with Moscow aimed at ending the conflict in Ukraine. Although the outcome of these discussions remains uncertain, it is increasingly apparent that the U.S. and Russia are moving toward finding common ground on their most contentious disputes. However, U.S. attempts to establish a lasting rapprochement with Russia will likely produce negative implications for Ukraine, undermining its sovereignty, and potentially impacting other borderland areas, notably the South Caucasus, where Russia challenges Western influence.

BACKGROUND: Each of the three South Caucasus countries—Armenia, Azerbaijan, and Georgia—has articulated distinct expectations regarding Trump's presidency. The Biden administration lacked a clear strategic vision for the South Caucasus, with Washington frequently oscillating between emphasizing human rights and democracy promotion (as exemplified by Georgia), and pursuing strategic calculations, such as swiftly signing a strategic partnership with Armenia to deepen the divide between Yerevan and Moscow. Washington's approach towards Azerbaijan similarly blended democratizing objectives with strategic considerations.

Under Biden’s administration, Georgia’s and Azerbaijan’s relations with the U.S. deteriorated, whereas Armenia, aiming to reduce its excessive reliance on Russia, benefited from Washington's policies between 2021 and 2024, culminating in the signing of a strategic partnership agreement in January. Consequently, all three states anticipate enhanced engagement from the Trump administration, with Azerbaijan and Georgia particularly expecting a significant shift toward greater transactionalism and realism in bilateral foreign relations.

Both Tbilisi and Baku have anticipated that under Trump their relations with the U.S. would improve. For example, Tbilisi supported the U.S.-backed UN resolution on Ukraine that diluted Russia’s responsibility for initiating the conflict. Similarly, Azerbaijani President Ilham Aliyev indicated in a statement that “…when President Trump led the U.S., our relationship developed very successfully—unlike the past four years, during which it significantly deteriorated owing to the Biden administration’s unfair and unjust stance toward Azerbaijan.”

IMPLICATIONS: A potential major agreement between the U.S. and Russia regarding Ukraine would likely affect the South Caucasus countries differently; however, the overall outcome may well be characterized by an expansion of Russian influence across the region.

Throughout Russia’s war in Ukraine, Moscow has faced significant challenges in maintaining its influence over the South Caucasus. Other powers, including China, Iran, Turkey, the Arab Gulf states, and even India, have expanded their presence in the region through substantial investments, trade agreements, and enhanced cooperation in security and energy sectors. This development has resulted in a period of regional multipolarity, where no single actor has been able to establish exclusive dominance. Consequently, Armenia, Azerbaijan, and Georgia have increasingly diversified their foreign policies, embracing a multi-vector approach beyond traditional partnerships.

Tbilisi and Yerevan have been notably successful in pursuing this strategy. For example, the Georgian government, while publicly maintaining its aspiration to join the EU, has concurrently signed a strategic partnership with China, enhanced cooperation with the Gulf Cooperation Council, and developed stable relations with Russia, despite the latter’s ongoing occupation of two Georgian regions. Armenia, aiming to reduce its reliance on Moscow, has sought increased military cooperation with India, explored the possible normalization of relations with Turkey, and, most significantly, announced its intention to seek EU membership.

Nevertheless, with a potential agreement on Ukraine, Russia would once again have the capacity to redirect resources into the South Caucasus to restore its weakened position. The Trump administration is unlikely to prioritize the smaller South Caucasus states, instead viewing the region primarily as within Russia’s sphere of influence. This approach aligns with Washington’s broader foreign policy objective of shifting its strategic focus toward the Indo-Pacific. Additionally, the U.S. lacks significant investments in the South Caucasus and shows limited interest in developing the Middle Corridor connecting Azerbaijan and Georgia to Central Asia.

More significantly, the South Caucasus states themselves increasingly perceive momentum shifting in the Kremlin’s favor and appear unlikely to oppose this declining trend. A potential agreement on Ukraine, which would solidify Russian gains, is expected to accelerate this shift toward Moscow. Indeed, Georgia and Azerbaijan have already anticipated such developments; what initially emerged as a policy of appeasement following Russia's invasion of Ukraine in 2022 has since evolved into a understanding that the balance of power in the region favors Russia. This shift partially reflects necessity, as Western powers were—and remain—unlikely to provide meaningful military assistance, while Russia continues to pose a credible threat despite its engagement in Ukraine.

Moreover, Georgia's approach reflects a deliberate foreign policy strategy implemented by the ruling Georgian Dream (GD) party, in power since 2012, aimed at developing a multi-vector diplomatic stance. Integral to this approach is the recognition of Russia's regional influence and a corresponding effort to maintain stable relations with Moscow. Although Georgia and Russia lack formal diplomatic relations, their bilateral economic ties have expanded considerably. Additionally, Tbilisi has subtly indicated declining enthusiasm for NATO and EU membership, both particularly contentious issues from Moscow's perspective.

In contrast, Baku possesses a considerably broader set of tools to counterbalance Russian influence, occasionally resulting in bilateral tensions, as exemplified by the recent incident involving a downed Azerbaijani aircraft. Nevertheless, geographical proximity, significant economic linkages, and Russia's formidable military presence will ultimately compel Azerbaijan toward reconciliation with Moscow. Indeed, signs of rapprochement are already evident through subtle gestures, such as the unveiling of a statue in Moscow honoring Heydar Aliyev, the father of current Azerbaijani President Ilham Aliyev, and Baku's hosting of the 22nd session of the bilateral inter-parliamentary commission.

Even in the case of Armenia, which signed a strategic partnership agreement with the U.S. shortly before Biden left office, it remains uncertain whether Washington will seriously commit to its implementation. Previous experiences are particularly instructive: between 2008 and 2024, Georgia maintained a strategic partnership agreement with the U.S., covering issues such as preparation for a free trade agreement, visa liberalization, and enhanced military and security collaboration. However, few tangible outcomes materialized, suggesting a similar pattern could emerge for Armenia. Early indicators are indeed discouraging, as evidenced by the reported postponement of a planned U.S. delegation visit to Yerevan. Additionally, Armenia's prospects for EU membership remain remote, given Georgia's ongoing difficulties with Brussels and internal disagreements within the EU regarding enlargement. Consequently, these factors will likely prompt Armenia to moderate its stance toward Russia, returning to full-scale cooperation even while maintaining certain aspects of its multi-vector foreign policy.

CONCLUSION: In the context of a potential rapprochement between Russia and the U.S. over Ukraine, the South Caucasus emerges as particularly vulnerable. Moscow would gain an opportunity to reassert its regional influence by filling the strategic vacuum left by an increasingly disengaged Washington. Additionally, Armenia, Azerbaijan, and Georgia are likely to recalibrate their foreign policies to align more closely with Russia. Although this trend has manifested in various forms over recent years, it is expected to accelerate significantly should Moscow successfully conclude its engagement in Ukraine.

Weakened by economic sanctions and bearing significant consequences for their geopolitical endeavors, Iran and Russia have solidified their post-2022 partnership, elevating it to the status of a comprehensive strategic partnership. The imperative to secure their borders and mitigate the impact of economic sanctions positions the South Caucasus and certain areas of the Caspian Sea as the focal points for deepening cooperation between Tehran and Moscow. Among the smaller regional actors, Azerbaijan is likely a primary beneficiary due to its geographically strategic location. Simultaneously, Russia may be inclined to reclaim some of its regional influence. This prospect is both precarious and potentially destabilizing for the region, as Russia’s historical engagement in the area has been characterized by conflict and disruptive interventions.

BACKGROUND: On January 17, Russia and Iran signed a Treaty on Comprehensive Strategic Partnership, marking the first high-level agreement between the two nations since 2001. Although historically characterized by tension and complexity, bilateral relations have undergone a significant transformation after 2022, in light of Russia’s war of aggression against Ukraine and its resulting international isolation. This period has seen a rapid elevation of Russian-Iranian ties, with some experts even suggesting the formation of an Entente.

The primary impetus behind this strengthening of relations lies in the challenges faced by both states. Politically isolated and subjected to extensive sanctions, Russia has become embroiled in a protracted and costly war. With limited strategic alternatives, Russian leadership has increasingly aligned itself with authoritarian regimes and internationally marginalized states—such as North Korea and Belarus—in an effort to mitigate the effects of its diplomatic and economic isolation and to secure critical military support.

Iran’s situation is arguably even more precarious. In addition to ongoing economic struggles and internal social unrest, Iran experienced a series of significant geopolitical setbacks between 2023 and 2024. At the end of 2024, the Tehran-backed regime of Bashar al-Assad was overthrown by the Turkish-supported opposition. Furthermore, the Israel-Hamas war inflicted severe damage on another of Iran’s key Middle Eastern proxies. These developments have reportedly exacerbated internal divisions within the Iranian political establishment, leading segments of Iran’s military-political elite to adopt a more critical stance toward Moscow.

Despite these disagreements, Russia and Iran remain compelled to act as close partners—if not outright allies—in the domains of defense and security, and perhaps even more so in trade and economic cooperation, as both seek to mitigate the detrimental effects of international sanctions. In this context, collaboration in the Caspian Sea region—particularly in specific areas of the South Caucasus—is expected to play a pivotal role in reinforcing Russo-Iranian ties.

IMPLICATIONS:  The strengthening ties between Russia and Iran are expected to have a significant impact on the geo-economic landscape. As emphasized by Russian President Vladimir Putin, "the essence of the Treaty [between Russia and Iran] is about creating additional conditions [...] for the development of trade and economic ties. We need less bureaucracy and more action." This objective is explicitly outlined in Clause 13 of the Treaty.

At present, economic and trade cooperation between Tehran and Moscow remains limited. In 2024, the reported trade volume between the two countries did not exceed US$ 4 billion. However, this may change in the future, primarily due to Russia’s evolving geopolitical strategy. Given its significantly weakened global position after 2022, Moscow increasingly views Iran as its “window to Asia”—a crucial conduit for circumventing Western-imposed economic sanctions and mitigating their severe economic impact.

In pursuit of this objective, Russo-Iranian cooperation is expected to strengthen in two key domains. First, there will likely be an intensification of trade along the International North-South Transport Corridor (INSTC)—a 7,200-kilometer multimodal freight route encompassing ship, rail, and road networks that connects India, Iran, Azerbaijan, Russia, and Central Asia. The INSTC is increasingly regarded as a viable alternative to traditional maritime trade routes such as the Suez Canal and the Bosphorus Strait.

Within this framework, Azerbaijan stands to be a primary beneficiary, as its strategic geographic position between Iran and Russia will elevate its role as a crucial transportation hub, significantly enhancing its economic and geopolitical importance within the region.

Azerbaijan’s role could be further reinforced if the two countries proceed with the construction of a natural gas pipeline through Azerbaijani territory. Initially agreed upon in 2022 and reaffirmed in late 2024, this project represents a significant expansion of regional energy cooperation. In his most recent statement on January 17, 2025, Russian President Vladimir Putin announced that the proposed pipeline would have a capacity of 55 billion cubic meters (bcm) of natural gas—equivalent to the Nord Stream 1 capacity—and could potentially be extended to Pakistan and even India.

However, some Russian experts question the economic viability of the project, arguing that its feasibility remains uncertain. They suggest that the pipeline could serve as a political instrument for Russia to exert pressure on China, possibly as a means of persuading Beijing to strengthen its energy ties with Moscow. Nevertheless, if both the International North-South Transport Corridor (INSTC) and the gas pipeline are successfully implemented, the South Caucasus—and Azerbaijan in particular—will see a marked increase in geopolitical and economic significance as a critical Eurasian transportation and energy corridor.

Although defense and security are not the primary focus of the Russo-Iranian Treaty, as explicitly stated by Iran’s Ambassador to Russia, Kazem Jalali, certain shifts in the regional security landscape are nonetheless anticipated.

One key factor influencing these dynamics is the aftermath of the Second Nagorno-Karabakh War (2020), resulting in an undisputed victory for Azerbaijan which not only received strong backing from Turkey but also enjoyed tacit Russian support. This outcome significantly weakened Iran’s position in the South Caucasus, while simultaneously bolstering its strategic adversary, Turkey. In addition to consolidating its influence over Azerbaijan, Turkey also strengthened economic, political, and energy ties with both Azerbaijan and Georgia, marking a substantial geopolitical success for Ankara and further diminishing Tehran’s leverage in the region.

However, in the post-2022 period, the geopolitical landscape of the South Caucasus has undergone further transformations, creating additional common ground for Russo-Iranian cooperation. The increasing prominence of Turkey, which directly contradicts the strategic interests of both Russia and Iran, has been a key factor in this shift.

Simultaneously, Russia’s influence over both Armenia and Azerbaijan has weakened. Armenia’s signing of a Charter on Strategic Partnership with the U.S. implies a diversification of its geopolitical partnerships, potentially reducing Moscow’s leverage in Yerevan. 

Moreover, by the end of 2024, anti-Russian sentiment became more pronounced in Abkhazia, a breakaway region that has been heavily reliant on Moscow. These developments have raised alarms among Russian analysts, some of whom have warned of Russia’s "approaching loss of the South Caucasus." While such statements may be premature and alarmist, they nonetheless reflect Moscow’s growing concerns regarding its long-term strategic foothold in the region.

Iran and Russia appear to prioritize a shared geopolitical objective: the de-Westernization of the South Caucasus and the prevention of strengthened U.S. regional influence. This strategic alignment is explicitly reflected in Clause 12 of the Russo-Iranian Treaty, which underscores both parties’ commitment to “strengthening peace and security in the Caspian Sea region, Central Asia, the South Caucasus, and the Middle East [to] prevent destabilizing interference by third parties” in these areas.

In this context, some experts suggest that Iran’s increased diplomatic involvement in regional affairs is likely. One potential avenue for such engagement is the "3+3" format, which includes Armenia, Iran, Russia, Georgia, Turkey, and Azerbaijan. Initially proposed by Ankara and Baku, the framework has since received active support from Moscow as a means to reduce the risk of Western powers gaining a foothold in the South Caucasus. Iran’s participation in this diplomatic initiative could further consolidate its regional influence while aligning with Russia’s broader strategic objectives.

CONCLUSIONS:  The expansion of Russo-Iranian ties is expected to have a notable impact on the South Caucasus and parts of the Caspian Sea region. Azerbaijan's geo-economic and geopolitical significance is likely to increase further, particularly if economic sanctions against Russia remain in place, compelling Moscow to deepen its reliance on alternative regional partners.

Russia, whose regional standing is in decline, might unexpectedly benefit from Iran’s strategic weakening. Given its growing security concerns, Tehran may become more inclined to collaborate with Moscow in the South Caucasus and the Caspian Sea region to safeguard its strategic depth and border security.

From a broader strategic perspective, a greater Russian presence in the region should be viewed as a negative development. Given the region’s complexity and history of conflict, Russia’s potential increased involvement—if it materializes—poses a significant risk. Historically, Moscow’s regional policies have regularly contributed to greater instability rather than fostering long-term security, raising concerns about the potential destabilizing consequences of renewed Russian engagement in the South Caucasus and Caspian Sea region.

In a time of geopolitical uncertainty, the South Caucasus and Central Asia have become more interconnected, forming a new Trans-Caspian area. As trade along the Middle Corridor is gaining in importance, the Caspian Sea is becoming a unifier rather than divider of the regions. All countries on the eastern and western side of the Caspian pursue multi-vector foreign policies to avoid overreliance on any single external actor. As the EU is seeking to assert itself geopolitically, it is in its strategic interest to support the evolving Trans-Caspian cooperation. To elevate its engagement with the countries in the South Caucasus and Central Asia, the EU should replace the outdated Eastern Partnership with a new Trans-Caspian Partnership. Such partnership would enhance regional connectivity and cooperation and give regional states greater collective weight in their dealings with different powers.
