The Caspian Sea is increasingly emerging as a focal point of geopolitical competition. The joint military exercises conducted by Russia and Iran in July, following similar drills by Azerbaijan and Kazakhstan in the northern Caspian a month earlier, underscore the region’s rapid transformation into a nexus of strategic rivalries and evolving security alignments. Among the littoral states, Azerbaijan, Kazakhstan, and Turkmenistan are assuming particularly prominent roles in shaping the strategic landscape. Their efforts are supported by Turkey, which is facilitating the naval expansion of these three Turkic nations. Russia’s ongoing involvement in the war in Ukraine has significantly weakened Moscow’s capacity to assert dominance over the Caspian Sea and to effectively utilize it as part of the International North–South Transport Corridor (INSTC) linking Russia to Iran and India.

BACKGROUND: The Caspian Sea was widely regarded as a “Russian lake” during the Soviet era, as Iran, possessing only a short Caspian coastline, showed little interest in utilizing it for power projection. For decades, Russia’s Caspian Flotilla maintained dominance over the waters of the inland sea. After the Soviet Union’s dissolution in 1991, Moscow sought to preserve the existing balance of power in the Caspian. In 2018, Russia secured an agreement among the five Caspian littoral states on territorial delimitation, excluding the military presence of non-littoral actors in the sea.

The region experienced a significant geopolitical shift in 2020 after Azerbaijan’s victory in the 44-day war against Armenia over the Nagorno-Karabakh region. Turkey provided military assistance to Azerbaijan during the conflict. Following the Azerbaijan-Armenia war, the Caspian littoral states expanded their navies. Turkey continues to support Azerbaijan’s requirements for modern weapons, equipment, and ammunition. In 2023, Azerbaijan’s Defense Minister, Zakir Hasanov, affirmed that Ankara was Baku’s principal partner in military cooperation.

Over the past five years, Turkey has facilitated the naval expansion of Kazakhstan, Azerbaijan, and Turkmenistan. These countries, along with Kyrgyzstan and Uzbekistan, are members of the Turkey-backed “Pan-Turkic Union.” Through this framework, Turkey has assumed a leading role in diminishing Russia’s influence over the military development of these states.

In 2023, Turkey’s Asfar and YDA Group, together with Kazakhstan’s Uralsk Plant “Zenit” JSC, concluded an agreement for the construction of offshore platforms in the Caspian Sea. The agreement included the production of various naval vessels, including main surface combat ships, to fulfill the operational requirements of the Kazakh Navy. Likewise, the deepening relations between Turkey and Turkmenistan signify a broader shift in energy geopolitics and highlight their shared strategic interests. The Bayraktar TB2, Turkey’s first domestically produced unmanned combat aerial vehicle (UCAV), is deployed within Turkmenistan’s armed forces. In February, the two countries signed a gas supply agreement that offers Turkmenistan a new export channel while consolidating Turkey’s position as a regional energy hub.

In 2024, the joint military exercises Birleistik (Unity) 2024 were conducted at Kazakhstan’s Oymasha training ground and Cape Tokmak along the Caspian coast, marking the first such drills held without Russian participation. The armed forces of Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan jointly participated in the exercise.

In April, Azerbaijan and Kazakhstan announced plans to conduct the joint military exercises Caspian Breeze – 2025 in the northern part of the Caspian Sea near Russia’s coastline. The exercises commenced in June at Aktau, Kazakhstan, with the objective of strengthening the protection of maritime economic infrastructure, naval bases, and shipping routes. A month later, Russia and Iran initiated their own joint naval exercises, CASAREX 2025, under the banner “Together for a Safe and Secure Caspian Sea.” These drills were designed to enhance maritime security and promote deeper naval cooperation between the two states.

The two joint military exercises within the span of a single month demonstrate a changing regional balance of power. The Caspian littoral states have expanded their naval capabilities in recent years, thereby challenging Russia’s long-standing hegemony in the Caspian region.

IMPLICATIONS: The navies of the three Turkic littoral states, Azerbaijan, Kazakhstan, and Turkmenistan, have experienced substantial growth and deepened cooperation in recent years. Through a series of bilateral and multilateral security agreements and supported by Turkey, these states have enhanced their strategic position vis-à-vis Russia. These developments have not only strengthened the collective influence and military capacity of the Turkic states but have also posed a significant challenge to Russia’s longstanding naval dominance in the Caspian.

Security cooperation among the three Turkic littoral states in the absence of Russian participation signifies a major geopolitical realignment in the Caspian region. For instance, Azerbaijan and Turkmenistan have agreed to employ their joint naval forces to protect pipelines on the seabed and vessels operating on the surface. The regional geopolitical competition is likely to intensify following Iran’s decision to resume drilling operations in the Caspian after a 30-year hiatus. This development could generate tensions with the three Turkic littoral states, which are already deeply engaged in offshore oil and gas extraction within the Caspian Sea.

Turkey plays a pivotal role in the ongoing militarization of the Caspian Sea. It initially strengthened Azerbaijan’s defense capabilities, subsequently supported Turkmenistan, and is now actively engaged in enhancing Kazakhstan’s naval power. According to Yuri Lyamin, an analyst at the Center for Analysis of Strategies and Technologies (CAST), “Kazakhstan is following the ongoing, multi-year process of strengthening the navies of Caspian states. The reasons and necessity of this can be debated, but it is a long-standing trend driven by prestige and the desire to keep up with its neighbors. Over the past decade and a half, Turkmenistan has built a very strong navy in the Caspian, including with Turkey’s assistance. It was to a Turkish design that Turkmenistan’s largest ship, and one of the largest warships in the Caspian, the corvette Deniz Khan, was commissioned and constructed in 2021. A considerable number of missile, missile-artillery, and other boats for the Turkmen border guards were also built based on Turkish designs.” The growing number of actors in the region is complicating Moscow’s ability to utilize the area for strategic connectivity projects. One of these is the International North–South Transport Corridor (INSTC), a Russia-led project designed to connect Russian ports with Iran, the Gulf region, and the Indian Ocean. The INSTC agreement was initially signed in 2000 by Russia, Iran, and India, was later joined by Azerbaijan and several Central Asian states. Meanwhile, Iran is actively seeking alternative trade routes to the EU, including via Armenia.

Conversely, Azerbaijan’s Port of Baku serves as a critical hub within the east–west Trans-Caspian Middle Corridor, which links China to the EU via Central Asia and the South Caucasus, thereby bypassing Russia. The Middle Corridor endows Baku’s with an important role for both Europe and Central Asia by providing a viable alternative to Russian transit routes, facilitating efficient east–west connectivity across the Caspian and through the South Caucasus.

Similarly, Turkey promotes the integration of Turkmenistan in the Middle Corridor, which would advance Turkey’s long-standing ambition to position itself as a strategic logistical bridge linking Asia and Europe.

The 2018 agreement grants the Caspian states the right to construct gas pipelines across the seabed. Ankara aims to channel Caspian gas to its territory via Azerbaijan, and onward to the EU, elevating Turkey’s role as a pivotal energy hub. However, this directly contradicts Russian interests and the potential exists for heightened tensions or even confrontation between the Turkey-backed Turkic states and the Russia-Iran alliance over control of the Caspian Sea’s energy resources.

CONCLUSIONS: The geopolitical competition between the three Turkey-backed Turkic littoral states and the Russia–Iran alliance could intensify as both sides continue to expand their economic and military presence in the Caspian region. The increase in military exercises conducted over the past two years underscores the emergence of new security alignments within the Caspian basin.

Turkey has taken on a leading role in advancing the naval capabilities of the three Turkic littoral states, a position that was traditionally held by Russia. As Turkey’s involvement in the region deepens, Moscow’s ability to shape the military development of these countries will likely be further marginalized. Russia, meanwhile, continues to bear significant geopolitical costs for its full-scale invasion of Ukraine in 2022. Since the onset of the conflict, Moscow’s influence across Central Asia and other regions, including the Caspian, has steadily declined and other powers such as China and Turkey have begun to fill the resulting vacuum.

During Azerbaijani President Ilham Aliyev’s visit to China in April 2025, he and Chinese President Xi Jinping announced the establishment of a comprehensive strategic partnership between China and Azerbaijan. For China, Azerbaijan represents a partner of considerable geostrategic importance, capable of functioning as a viable transit hub linking China, Central Asia, and Europe. Azerbaijan offers China access to the sole overland route to Europe that circumvents Russia. Furthermore, China’s pathway to the South Caucasus necessarily passes through Azerbaijan, positioning Baku as a pivotal actor in China’s Eurasian economic strategy. Conversely, Chinese investments have the potential to place Azerbaijan’s non-oil economy on a trajectory of diversification. A strategic partnership with Baku is thus poised to expand Beijing’s influence in the South Caucasus.

BACKGROUND: Historically, relations between China and Azerbaijan trace back to the ancient Silk Road, along which trade and cultural exchanges took place over 2,500 years ago. In December 1991, China recognized Azerbaijan’s independence, and diplomatic relations were formally established with the Caucasian state in April 1992. China inaugurated its embassy in Baku in 1992, while Azerbaijan opened its embassy in Beijing in 1993. Azerbaijan was among the first states to accede to China’s multi-trillion-dollar Belt and Road Initiative (BRI), launched in 2013. Designed to enhance global connectivity through investments in infrastructure, energy, and transportation, the BRI extends across more than 160 countries. In 2015, China and Azerbaijan concluded a memorandum of understanding on the joint development of the Silk Road Economic Belt.

In 2019, President Ilham Aliyev traveled to Beijing to attend the “Belt and Road” International Forum, during which the two states signed ten agreements to strengthen cooperation in industry, investment, trade, and other economic sectors. The BRI has functioned as a catalyst for the rapid expansion of China–Azerbaijan relations, which have evolved over the years from commercial, economic, transit, and logistics collaboration to cooperation in science, technology, and cultural exchange.

In 2024, the two nations, during a Shanghai Cooperation Organization (SCO) summit in Astana, reached another milestone in bilateral relations by adopting the “Joint Declaration of the Republic of Azerbaijan and the People’s Republic of China on the Establishment of a Strategic Partnership.”

In April 2025, China–Azerbaijan relations were elevated to a comprehensive strategic partnership, inaugurating a new chapter in bilateral ties. During talks with the visiting President Aliyev on April 23 in Beijing, President Xi emphasized that the two states should “continuously enhance political mutual trust, deepen practical cooperation, and strengthen international collaboration to open a new chapter of all-round cooperation.”

The timing and context of Azerbaijan’s decision to sign a comprehensive strategic partnership with China were of considerable significance. In April, scarcely two weeks prior to the agreement with Beijing, President Aliyev warned that Azerbaijan might redirect its gas exports elsewhere should the EU fail to advance the expansion of the Southern Gas Corridor, a transit route currently functioning at near-capacity. Azerbaijan supplies gas to the EU via this corridor, and Baku wants the EU to support its enlargement, as exports fell to 2.84 bcm in the first quarter of 2025, compared with 3.2 bcm during the same period the previous year. While EU investment could enhance pipeline capacity to achieve the 20 bcm target by 2027, skepticism persists within the EU regarding Azerbaijan’s ability to sustain sufficient gas supplies.

IMPLICATIONS: Geographically, the South Caucasus is of interest to China as it offers a potential land route linking China with Europe. For this reason, Beijing last year formally joined the Middle Corridor, a trade route connecting Europe and China that bypasses Russia and serves as an alternative to the Northern Corridor through Russia and to traditional maritime routes. Participation in the Middle Corridor is part of China’s broader strategy to diversify its trade routes.

For China, the present moment is opportune for expanding its presence in Central Asia and the South Caucasus, where Russia has been rapidly losing influence due to its war in Ukraine since February 2022. The ongoing transformation of the Eurasian geopolitical landscape has brought renewed attention to Azerbaijan’s role as a transit state between Europe and Asia. Within the rapidly evolving regional dynamics shaped by Russia’s war against Ukraine, Azerbaijan has gained centrality in China’s Eurasian economic strategy.

Situated at the intersection of China’s East–West and North–South transportation routes, Azerbaijan has figured prominently on Beijing’s agenda for advancing its economic and strategic objectives in the region. China regards Azerbaijan as a pivotal partner for extending its influence across Central Asia and the South Caucasus. As a key actor in the South Caucasus for the EU, Russia, and China alike, Azerbaijan plays an important role in the BRI by facilitating strategic connectivity projects. The Baku–Tbilisi–Kars railway (BTKR), for instance, links the Trans-European and Trans-Asian railway systems. This project not only grants the five Central Asian republics and Afghanistan access to the EU but also expedites the movement of Chinese goods into European markets. Likewise, Azerbaijan provides China access to the Baku International Sea Trade Port within the BRI framework. Located on the historic Silk Road, the Port of Baku functions as a major transport and logistics hub connecting Europe and Asia, and constitutes a vital component of the Trans-Caspian International Transport Route, or Middle Corridor.

Azerbaijan’s strategic connectivity initiatives possess the capacity to transform the Caucasian state into a major transport and logistics hub of the region. For this reason, China envisions a pivotal role for Azerbaijan in advancing the prospects of the BRI and ensuring the success of its Eurasian economic strategy.

At present, transport and logistics constitute the principal domains of China–Azerbaijan cooperation, though this partnership may expand to include military collaboration. Azerbaijan has already procured Pakistan’s JF-17 Thunder Block-III fighter aircraft, a joint venture between the Pakistan Aeronautical Complex Kamra and China’s Chengdu Aircraft Industry Corporation. Beijing could further augment Azerbaijan’s military capabilities as it consolidates its strategic presence in the South Caucasus in the capacity of Baku’s strategic partner.

The EU constitutes Azerbaijan’s principal export market and thus its leading trading partner. Baku’s intensifying relations with Beijing illustrate its efforts to lessen dependence on traditional routes and markets while diversifying foreign policy options. As this partnership deepens, Azerbaijan may permit Chinese state-owned enterprises to assume greater control over ports, railways, and other strategic infrastructure in the region, a development likely to raise concern in European capitals. Moreover, the competing interests of various geopolitical actors in the region could erode the degree of autonomy that Baku presently enjoys in shaping regional policies. Regional powers such as Russia, Turkey, and Iran may perceive a challenge to their strategic interests in the region arising from a deepening China–Azerbaijan strategic partnership.

CONCLUSIONS: By virtue of its position at the crossroads of Europe and Asia, Azerbaijan possesses significant potential to serve as a viable transit hub linking China, Central Asia, and Europe, particularly at a time when Beijing, engaged in a trade war with Washington, is actively seeking alternative routes for its exports.

Azerbaijan’s strategic partnership with China is, however, likely to generate new foreign policy challenges for the Caucasian state. A further deepening of this partnership may constrain Azerbaijan’s capacity to sustain strategic balance in its foreign policy. The country’s integration with European energy markets and its relations with Western states could, at some point, come into conflict with China’s interests in the region.

At present, China is not in a position to shape the geopolitics of the South Caucasus given the presence of other key actors such as the EU, Russia, Turkey, Iran, and the U.S. Beijing has, however, placed its bet on Azerbaijan, which it regards as a pivotal node in strategic connectivity initiatives such as the Middle Corridor. China further views a strengthened strategic partnership with Azerbaijan as essential to consolidating its position in the South Caucasus.

The U.S.-brokered peace talks between Armenia and Azerbaijan, culminating in the creation of the Trump Route for International Peace and Prosperity (TRIPP), have triggered a sharp strategic reaction from Iran. The 20-mile corridor through Zangezur grants Azerbaijan direct access to Nakhchivan under long-term U.S. management, reshaping regional connectivity and bypassing Iran. Tehran perceives the initiative as a U.S. encroachment on its northern frontier, eroding its leverage in the South Caucasus. The muted Russian response and Armenia’s growing openness to Western—and potentially Israeli—security ties deepen Iran’s unease, fueling fears of encirclement and diminishing its role as a key regional transit hub.

BACKGROUND: Brokered by the U.S., the latest Armenia–Azerbaijan peace talks have quietly but decisively reshaped the balance of power in the South Caucasus. At the heart of the deal is a newly designated transit Zangezur Corridor, officially named the Trump Route for International Peace and Prosperity (TRIPP), which would grant Azerbaijan direct access to its Nakhchivan exclave through southern Armenian territory. Moscow has responded with unusual silence, while Tehran has openly bristled at the emergence of a U.S.-designed transit network on its northern frontier.

Iran’s initial reaction to the U.S.-brokered Armenia–Azerbaijan peace framework has been visceral, with some prominent media organs terming it a “betrayal”. Tehran explicitly sees TRIPP as a U.S. footprint pressed onto its northern frontier. The plan envisions a 20-mile corridor through Armenia’s Syunik region, linking Azerbaijan to its Nakhchivan exclave, with development rights leased to a U.S. consortium for up to 99 years. More than redrawing borders, the project reshapes the balance of power and places a sustained U.S. commercial and political presence in the narrow strip where Iran has long turned geography into strategic leverage.

IMPLICATIONS: Iran interprets the recent Azerbaijan–Armenia peace talks not only as a potential shift in the regional balance of power but also as part of a broader geopolitical environment increasingly hostile to its interests. Tehran worries that a settlement, especially one facilitated or backed by Western actors (including Turkey), could strengthen Azerbaijan’s position, deepen Baku’s security and economic ties with the West and Israel, and reduce Iran’s leverage in the South Caucasus. These concerns are amplified by the expanding footprint of the U.S. and Israel in Azerbaijan, from intelligence cooperation to defense technology transfers, which Tehran perceives as part of a containment strategy aimed at its northern flank. Against this backdrop, any peace process that sidelines Iran or solidifies the U.S. influence in the region risks, in Tehran’s view, to tighten the strategic noose around its borders.

Iran’s historical memory of regional threats plays a significant role in shaping its foreign policy reflexes. In addition to the growing perception of U.S. and Israeli threats following the 1979 Islamic Revolution, the Soviet invasion of Afghanistan further heightened Tehran’s sense of vulnerability. Iranian officials, suspecting that the Soviets might use the Baloch as a stepping stone toward making Iran their next target, began seeking countermeasures. After the Soviet collapse, the country continued to frame its foreign policy around an intensifying rhetoric of U.S. and Israeli danger and the cooperation of Azerbaijan with these powers. Today, Washington’s renewed bid to reassert influence in the region is likely to aggravate Iran’s geopolitical anxieties, with indirect repercussions visible in Iran–Azerbaijan relations.

Tehran’s messaging, while varied in tone, consistently reflects unease about the deal. Ali Akbar Velayati, senior adviser to the Supreme Leader, warned that the corridor would become a “graveyard” for its backers; a classic piece of deterrent rhetoric aimed at raising costs and sowing doubt. At the same time, the Foreign Ministry expressed conditional support for a peace deal in principle, while cautioning against “foreign interference” near Iran’s borders. President Masoud Pezeshkian said that Iran’s core demand had been met, yet voicing unease over U.S. corporate involvement.

Tehran is not worried about lines on a map. It is losing the bargaining power that those lines used to confer. A corridor under Armenian law deprives Iran of the sovereignty argument it used against an “extraterritorial” Zangezur model, outside Armenian jurisdiction. However, U.S. stewardship narrows Iran’s room to shape rules, customs, and security practices at the edge of its border. A U.S.-organized logistics spine running from Turkey via Nakhchivan to Azerbaijan (tightening connectivity between Turkey and Central Asia) offers a shorter, more secure east–west route that bypasses both Russia and Iran.

The Russian reaction intensifies Iran’s dilemma. Moscow’s muted response by accepting a U.S. role while cautioning against “foreign meddling” signals that Russia, overstretched and weakened in credibility after the 2020 Second Karabakh War, lacks the capacity or will to reshape the deal. For Tehran, this translates into fewer veto options by proxy and a thinner buffer against Turkish and U.S. coordination. It also incentivizes Yerevan to deepen ties with Western partners, which is not acceptable for Tehran.

Economically, the corridor undermines Iran’s claim to constitute an indispensable regional bridge. Tehran has long positioned itself as the key link between the Persian Gulf, the Caucasus and the Black Sea, with initiatives like the International North–South Transport Corridor and electricity and gas swaps with Armenia designed to cement that role. A functioning TRIPP route diverts attention and investment toward the “Middle Corridor,” lowering the premium shippers pay for transit through Iran and shrinking Tehran’s leverage to extract side deals on access, security assurances or energy flexibility. Iran’s alternative options remain limited, as seen in its cautious approach to the Gulf of Hormuz closure in June 2025.

Security risks run in both directions. For Tehran, a U.S.-supervised logistics corridor along its northern frontier would invite surveillance and restrict its gray-zone tactics. Yet overt interference such as through intimidation, sabotage, or proxy harassment would likely backfire. Such moves could strengthen U.S.–Turkish coordination (and even Azerbaijani-Israeli coordination), justify reinforced security around the route and push Armenia toward even closer alignment with Washington and Brussels. Iran’s own experience shows that coercion is most effective when opponents lack a unifying patron; TRIPP provides precisely that.

Still, Tehran has a few levers left. The first is regulatory: it can push for “no military use” clauses, real-time customs transparency and verified policing regimes that limit the route’s securitization. The second is connectivity hedging. The new route builds upon Iran’s already existing north–south connections with Armenia, including the Meghri–Julfa railway link, expanded electricity exchanges, and predictable gas swaps. Thus, the U.S.-managed corridor supports, rather than replaces, Iranian routes. The third is political triangulation. Iran maintains open channels with Ankara on trade and energy, where their interests sometimes overlap, while giving Yerevan price and reliability benefits that only a neighboring country can offer.

CONCLUSIONS:  Then, what is the balance sheet? In the short term, Iran faces a strategic setback in shaping the regional agenda. The U.S. has demonstrated its ability to achieve outcomes in the South Caucasus that Moscow could not, and the corridor effectively puts a purely Western hand on the flow of regional connectivity (the role of Turkey is also extremely important). In the medium term, Tehran can still limit the impact by quickly upgrading its own corridors, offering competitive transit pricing, and securing Indian and Gulf participation in north–south routes, turning competition into redundancy rather than outright replacement. Over the long term, the key question is whether Iran can tolerate a U.S. presence next door while extracting enough rules and linkages to avoid strategic encirclement.

An additional factor complicates this calculus: the possibility of an Israel–Armenia security partnership. While historically limited, such a relationship becomes more logical in a post-peace-deal environment where Yerevan seeks diversified defense ties beyond Russia and the West. This possibility is already being discussed in various circles. Israeli defense technology, already embedded in Azerbaijan, could find a foothold in Armenia in the form of counter-drone systems, border surveillance or intelligence sharing, especially if framed as balancing Ankara–Baku military cooperation. For Tehran, this would imply Israeli-linked security infrastructure on both its northwestern and northern flanks, eroding any remaining buffer zones and deepening the perception of encirclement. In such a scenario, even an economically beneficial TRIPP corridor would be overshadowed by the strategic risks it amplifies.

In Washington on August 8, 2025, the presidents of Armenia and Azerbaijan signed what amounts to a framework for a peace treaty. The agreement ratified both sides’ support for creating the Trump Route for International Peace and Prosperity (TRIPP) in the area formally known as the Zangezur corridor, in Armenia’s Syunik province, and entrusts management of the corridor to a U.S. private company on a 99-year lease. It is also likely that U.S. security personnel will supervise the corridor’s planned intermodal rail and highway transportation. As a result, Azerbaijan will have direct overland contact with its Nakhchivan province while a direct land route will be established from the Caspian Sea straight through to Turkey, allowing a substantial growth of Central Asian trade with Europe. The agreement represents the first and considerable sign of a tangible U.S. presence in the Caucasus and comes at the expense of Russian and Iranian interests.

BACKGROUND: After many years of unclear U.S. policies towards Central Asia and the Caucasus, the Trump Administration has made a major move to upgrade U.S. presence in the Caucasus and provide a decisive impetus towards the conclusion of a peace treaty between Armenia and Azerbaijan as well as a strong impetus for the so-called Middle Corridor between Asia and Europe. 

The Zangezur corridor has been a bone of contention in the Armenian-Azerbaijani peace talks to terminate the conflict over Nagorno-Karabakh, since the corridor passes through Armenia. This “sliver” of territory has been at the heart of disputes dating back to the Soviet conquest of Armenia and Azerbaijan in 1920-21, when the Soviet leadership deliberately separated Nakhchivan from Azerbaijan to prevent its proximity to Kemalist Türkiye. Armenia’s conquest of Nagorno-Karabakh in 1993-94 led to widespread ethnic cleansing and thousands of Azeri refugees as well as a strong Azeri irredentist movement that has now triumphed over Armenia and led Pashinyan’s government to sue for peace.

Domestic nationalist opposition in Armenia has vigorously protested Azerbaijan’s demand for the corridor, which would connect it to both Nakhichevan and Türkiye with potentially huge economics payoffs for both states. The issue has generated an impasse in the bilateral negotiations, often directly conducted by Presidents Pashinyan and Aliyev. The domestic pressure in Armenia and from the Armenian diaspora to refuse concessions to Azerbaijan has triggered a serious domestic crisis leading Pashinyan to arrest high-ranking members of the church on the grounds that they were plotting a coup. There is some evidence of Russian support for the coup plotters. Pashinyan’s reform agenda is anathema to Armenian reactionaries and nationalists are resisting what they call a surrender to Azerbaijan. Moscow evidently has its own interests in backing these disaffected elites to reverse Pashinyan’s reforms to prevent their emulation elsewhere. Moreover, strife between Yerevan and Baku benefits Moscow, allowing it to play the states off against each other and regain its influence in Armenia. Indeed, it has reinforced its military presence in Armenia despite the war in Ukraine.

IMPLICATIONS: In this context, Trump’s offer could present a way out of the current impasse. Washington will pay Armenia for a 99-year lease of the corridor, which would formally respect Armenia’s sovereignty but give the U.S. operating control over the area and allow it to place forces there to maintain the corridor and provide security. Armenia has previously hinted that it might be open to a proposal that preserves its sovereignty but allows for third party management of the corridor. The U.S. proposal allows Baku and Yerevan to sidestep the vexed question of sovereignty over the corridor until passions have subsided. Azerbaijan, meanwhile, gets de facto ability to link with Nakhchivan and to operationalize the routes traversing this territory. A working and well-maintained overland trade route to Türkiye, Europe, and the Levant constitutes a giant step towards consummating the Middle Corridor from China to Europe, allowing Azerbaijan to benefit as a key middleman on this route. At the same time, Armenia needs peace to deal with its domestic opposition, institute Pashinyan’s democratic agenda, and terminate the state of war so that Armenia can restore relations with Türkiye and profit from the expansion of international trade corridors into the Caucasus. The agreement also incentivizes both sides to move quickly towards a peace treaty where they and neighboring states, including in Central Asia, stand to gain economically and politically.

Trump’s proposal also works to stabilize the Caucasus by minimizing Russian opportunities for interference. For over a century, Russia has endeavored to manipulate the tensions between Armenians and Azeris to enhance its imperial reach and standing in the Caucasus. Azerbaijan’s victories of 2020 and 2023, plus the pressure of the war in Ukraine have forced Russia to retreat in the Caucasus and elsewhere. The agreement will likely strengthen Pashinyan’s government at home against his pro-Russian and Russian-backed enemies. Moreover, Trump’s proposal, by creating a basis for completing the Middle Corridor, undermines Russia’s increasing efforts to create an International North-South Trade Corridor (INSTC) from India to Iran, Central Asia and Russia. Despite much recent Russian diplomatic effort, this proposed route is nowhere near as complete as China’s Belt and Road Initiative, which relies on the Middle Corridor that bypasses Russia.

Türkiye stands to make major gains through this proposal and clearly supported it as part of its improving ties with Washington. While Russia sought to exploit Armeno-Azeri tensions; Türkiye’s massive aid to Azerbaijan’s military and alliance agreement with it gave it a lasting presence in the Caucasus. Washington seems to be at peace with this outcome, and the proposal could only have come about with Turkish support behind the scenes. This U.S.-proposed solution therefore enhances Türkiye’s reach and power projection through the Caucasus, which is increasingly important to Ankara given its rising multi-dimensional profile in both the Caucasus and Central Asia. 

Beyond the serious implications for local actors, the proposal entails equally meaningful consequences for actors beyond the Caucasus. Iran, for example, is a major loser and has already declared its opposition. After its defeat by Israel and the U.S. it has no choice but to make a rapprochement of some sort with Azerbaijan. Simultaneously, Iran’s connection to Armenia will be seriously impaired and it will no longer be able to resupply Armenia with weapons or incite resistance against Baku over Zangezur. Furthermore, the real possibility of completing the Middle Corridor with U.S. help would imply a lasting U.S. presence on Iran’s northern border. This will seriously complicate Iran’s ability to rebuild either its network of terrorist proxies or its nuclear program.

Conversely, China gains from this proposal. If it materializes, it will give a major impetus to the realization of China’s BRI and the accompanying Middle Corridor. It also buttresses China’s growing economic position in the Caucasus most prominently embodied in its development of the Anaklia port in Georgia. China has invested considerable economic and political capital in the combination of major land and maritime trade and transport routes. If implemented, the proposal will represent another instance whereby China has gained influence and position in Eurasia at Russia’s expense.

The proposal also permits the EU an opportunity to expand its presence in Armenia and the Caucasus. A democratizing Armenia, freed of the Nagorno-Karabakh incubus, is already seeking EU membership. The EU also buys large amounts of Azerbaijan’s oil and gas and the prospect of real peace in the Caucasus can only redound to its benefit. The EU also stands to gain from the completion of the Middle Corridor, which provides it with a secure land route for trade to and from the Caucasus, Central Asia, and China.

CONCLUSONS: Finally, and perhaps most importantly, the proposal constitutes the first major U.S. initiative in the Caucasus and Central Asia since the Clinton Administration helped develop the Baku-Ceyhan pipeline to connect Transcaucasian oil to European markets. While consonant with the Administration’s overall perspective of using large-scale economic projects and/or trade opportunities as instruments to facilitate peaceful solutions to long-lasting wars, the proposal also marks the first sign that Washington realizes the importance and opportunity presented by the independence of South Caucasian states. If this project is implemented, awareness will likely grow that the Caucasus and Central Asia offer Washington many genuine and plentiful opportunities for increasing its economic and political influence.

This project may also reflect a growing U.S. awareness that the Caucasus and Central Asia are areas of strategic significance that both want a consistent engagement with Washington and offer new and exciting vistas regarding energy, rare earths, trade, investment, large-scale environmental cooperation, and security cooperation. That awareness has hitherto been missing in U.S. policy. Indeed, Trump’s policies regarding these regions has been quite inconsistent given Trump’s imposition of tariffs – exactly the wrong move – on Kazakhstan, Uzbekistan, and their neighbors. Policymakers need to understand the necessity and benefits of long-lasting partnerships for all parties since this project, if it comes to pass, creates opportunities for peace, cooperation among many international actors, enhanced trade, and greater independence for the South Caucasian states. These outcomes are not only in the interests of Azerbaijan and Armenia; they could also become the basis for very different development in the Caucasus than has been the case in the past.

Armenia stands at a critical crossroads as it seeks to break free from Russian influence and integrate with the West. Following recent peace talks with Azerbaijan in Abu Dhabi and the proposed U.S.-overseen Zangezur Corridor, Armenia has a unique opportunity to transform its geopolitical position. The nation must navigate four key strategic priorities: normalizing relations with Turkey despite historical tensions over the Armenian Genocide, accelerating EU and NATO integration while strengthening democratic institutions, developing strategic industries including defense manufacturing partnerships with Europe, and leveraging the Zangezur corridor to deepen ties with India as an emerging defense partner. With the pivotal 2026 parliamentary elections approaching and Russia intensifying hybrid attacks to destabilize the government, Armenia's choices will determine whether it consolidates as a democratic, pro-Western anchor or reverts to dependence and instability.
