Construction of the northern section (Heihe-Changling) of the China-Russia east-route natural gas pipeline has entered the stage of finishing.

The 3,371-km-long Chinese section of China-Russia east-route natural gas pipeline starts in Heihe and terminates in Shanghai. Construction began in June 2015 and will be completed in 2020. The Russian part of the pipeline, which started construction on Sept. 1, 2014, will link the Kovyktin and Chayandin gas fields in Siberia with the eastern port city of Vladivostok, covering a total distance of nearly 4,000 km. Upon completion, the pipeline is expected to provide China with 38 billion cubic meters of natural gas from Russia annually.
