New energy cooperation projects are being carried out in full swing between China and Russia as the interdependency of the two economies has been strengthened.

An underwater shield-crossing project that passes through the Yangtze River of the China-Russia Eastern Gas Pipeline is in full swing, which is the key project of the southern section of the China-Russia Eastern Gas Pipeline. It has a total length of 10.226 kilometers, and it's the longest tunnel under construction across the Yangtze River.

On February 3, China National Petroleum Corp (CNPC) and Russia's Gazprom signed an agreement on the purchase and sale of gas from the Russian Far East, another important result of cooperation in gas trade.

Under the agreement, Russia will increase its pipeline gas supply to China by 10 billion cubic meters a year, which, together with the "Siberian Power" pipeline, will bring total gas supply to China to 48 cubic meters per year.
