Turkish Energy Minister Hilmi Guler has confirmed that Turkey and Turkmenistan are holding talks on the construction of a trans-Caspian natural gas pipeline. Guler said, \"We will go on [with] negotiations with Ashgabat on implementation of the trans-Caspian gas pipeline project. There is a contract between Turkey and Turkmenistan on gas supplies which for certain reasons had not been realized.\" Guler\'s comments came on the eve of a visit to the United States. Turkey and Turkmenistan signed a contract in 1991 to build the pipeline, but it has never moved beyond the planning stage. (Trend news)
