By the end of 2015, total length of China's long-distance gas pipelines has exceeded 70,O00km. Onshore stratey, ic import paths have been formed, domestic trunk networks perfected and gas storages construction pace acceh'rated. The Chinese section of Russia-China East Gas Pipeline was officially commenced, which marked that the northeast import path entered the stage ofconstruction. There are 13 LNG terminals in China. The National Development and Rerorm Commission (NDRC) approved China's.first private-owned LNG terminal- the Zhoushan LNG terminal. In the coming.five years, the focus of institutional reform will be the independence of pipelines and networks, the focus of construction will be regional networks and branch pipelines, and joint ventures will be the mainstream for gas pipeline construction and operation. 展开更多
