Chinese and Russian companies are now negotiating for a new China-Mongolia-Russia natural gas pipeline project, the National Energy Administration said on Wednesday.

The project is designed to carry 50 billion cubic meters of gas from Russia to China per year upon completion, which will bring Russia's annual gas supply to China to 100 billion per year according to Gazprom, a Russian state-owned energy enterprise and one of the project's undertakers
