Trans-Asia Gas Pipeline Company recently signed an agreement with Tajiktransgaz to jointly establish a natural gas pipeline company to manage the construction of Line D of the Central Asia-China Gas Pipeline.

The agreement was signed in Duschanbe, the capital city of Tajikistan.

Preparation for construction of Line D began soon after the signing of a 25 Bcm/a gas supply increase agreement between China and Turkmenistan in November 2011. In September 2013, the Chinese Government signed inter-governmental agreements with Uzbekistan, Tajikistan, and Kyrghyzstan, respectively, for the Line D project. Currently, the feasibility studies of the project have been completed by Trans-Asia Gas Pipeline Company.

Construction of the Tajikistan section of Line D is expected to start this year. By the end of China's 13th Five-Year Plan period (2016–20), when construction of Line A/B/C/D and the auxiliary facilities in China are completed, 80 Bcm of natural gas will be transported from Central Asia to China on an annual basis, taking over 40 per cent of China’s gas imports of the year.
