A staff member walks past pipelines in the gas-distributing and compressing station of the China-Russia east-route natural gas pipeline in the city of Heihe, the first stop after the Russia-supplied natural gas enters China, northeast China's Heilongjiang Province, Nov. 19, 2019. The China-Russia east-route natural gas pipeline was put into operation on Monday. The pipeline is scheduled to provide China with 5 billion cubic meters of Russian gas in 2020 and the amount is expected to increase to 38 billion cubic meters annually from 2024, under a 30-year contract worth 400 billion U.S. dollars signed between the China National Petroleum Corp (CNPC) and Russian gas giant Gazprom in May 2014. The cross-border gas pipeline has a 3,000-km section in Russia and a 5,111-km stretch in China. (Xinhua/Wang Jianwei)
