Longest pipeline will help increase transportation of natural gas

China and Turkmenistan vowed on Tuesday to be "long-term, stable and reliable" energy partners and ensure the annual transport of 65 billion cubic meters of natural gas to China by 2016 through the world's longest natural gas pipeline.

President Xi Jinping and his Turkmen counterpart Gurbanguly Berdymukhamedov made the announcement in a joint declaration in Ashkhabad, the first stop of Xi's visit to Central Asia.

"The two countries will be long-term, stable and reliable energy partners," Xi said when meeting reporters with Berdymukhamedov. He described natural gas cooperation as strategic and forward-looking.

A joint declaration announced the establishment of a strategic partnership between the two nations.

"Today is an important day for Turkmen-Sino relations. The two countries signed a joint declaration to raise the ties to a new level of strategic partnership. That means from today on, no matter how the regional and global situation changes, developing the Turkmen-Sino relationship will always be the priority of both nations," Berdymukhamedov told reporters.

The declaration also said the two nations will make joint efforts to build Line C and Line D of their natural gas pipeline to ensure the annual target of 65 billion cubic meters of gas is met by 2016.

They will also set up a cooperation mechanism to ensure security of the natural gas projects, the paper said.

Xi said the two nations will push forward cooperation in other fields including infrastructure, telecom and high-tech to make the relations "more comprehensive and balanced".

Relations between the two have grown smoothly since Beijing and Ashkhabad set up diplomatic ties in 1992.

China is Turkmenistan's largest trade partner. Trade hit $10.37 billion in 2012, almost double the figure in 2011.

Turkmenistan is China's major supplier of natural gas, and China is the largest overseas market for Turkmenistan's natural gas.

The two have put into operation the world's longest natural gas pipeline of more than 8,000 km.

Completed in 2009, the pipeline brings vital energy supplies through China's western region.

It is estimated that 400 million people in China benefit from natural gas from Turkmenistan.
