After September 11 attacks some people came to believe that a possible motivation for the attacks included justifying the invasions of Afghanistan as well as geostrategic interests such as the Trans-Afghanistan Pipeline project . The new deal on the pipeline was signed on 27 December 2002 by the leaders of Turkmenistan , Afghanistan and Pakistan . In 2005 , the Asian Development Bank submitted the final version of a feasibility study designed by British company Penspen . The project has drawn strong US support as it would allow the Central Asian republics to export energy to Western markets " without relying on Russian routes " . Then-US Ambassador to Turkmenistan Tracey Ann Jacobson noted , " We are seriously looking at the project , and it is quite possible that American companies will join it " . Due to increasing instability , the project has essentially stalled ; construction of the Turkmen part was supposed to start in 2006 , but the overall feasibility is questionable since the southern part of the Afghan section runs through territory which continues to be under '' de facto '' Taliban control
