Turkmenistan - The Caspian Issue.
Long-standing and complex territorial disputes among the Caspian Sea's littoral states have hampered efforts to develop this basin, which has large gas and oil deposits. Russia, Iran, Turkmenistan, Azerbaijan and Kazakhstan have argued about the delimitation of the sea since the break-up of the Soviet Union in late 1991.
However, Turkish Minister Yildiz in 2010 noted: "There are places where the borders are not disputed. We could seek natural gas. That is from areas which have no problems with the border or the status, which is being exploited offshore from Turkmenistan's sector of the Caspian Sea".
