On 24 April 2008, Pakistan, India and Afghanistan signed a framework agreement to buy natural gas from Turkmenistan. The intergovernmental agreement on the pipeline was signed on 11 December 2010 in Ashgabat. However, in April 2012, India and Afghanistan have failed to agree on transit fee for gas passing through Afghan territory. Consequently, Islamabad and New Delhi too could not agree on the transit fee for the segment of the pipeline passing through Pakistan, which has linked its fee structure to any India-Afghanistan agreement. On 16 May 2012, the Afghan Parliament, approved the agreement on a gas pipeline and the day after, the Indian Cabinet allowed state-run gas-firm GAIL to sign the Gas Sale and Purchase Agreement (GSPA) with Türkmengaz, Turkmenistan's national oil company.
