2nd line of China-Russia oil link starts

The second line of the China-Russia oil pipeline began commercial operation on Monday, another step in diversifying China's energy supply and ensuring its energy security, according to China National Petroleum Corp, the country's biggest oil producer.

With an annual capacity of 15 million metric tons, the project is expected to double China's annual imports of Russian crude oil to 30 million tons, filling the supply gap caused by the decline in crude oil production in northeastern China.

The 941.8 kilometer long line starts from Mohe in Northeast China's Heilongjiang province, which borders Russia, crosses North China's Inner Mongolia autonomous region, and ends in the city of Daqing in Heilongjiang. Its construction began in August 2016 and ended in November 2017.
