In the spring of 1992, the Turkish Prime Minister Süleyman Demirel proposed to Central Asian countries including Azerbaijan that the pipeline run through Turkey. The first document on the construction of the Baku–Tbilisi–Ceyhan pipeline was signed between Azerbaijan and Turkey on 9 March 1993 in Ankara. The Turkish route meant a pipeline from Azerbaijan would run through Georgia or Armenia, but the route through Armenia was politically impossible due to the unresolved war between Armenia and Azerbaijan over the status of Nagorno-Karabakh. This left the circuitous Azerbaijan-Georgia-Turkey route, longer and more expensive to build than the other option.
