Russia will start supplying natural gas to China through a new pipeline by the end of 2019 as part of the two countries $400 billion energy pact.

Aleksei Miller, Gazprom Chief Executive announced that Moscow that delivery of gas would start on pipeline called Power Of Siberia on December 2019, and also that Beijing and Moscow are now negotiating over a second Far Eastern gas pipeline.

Russia signed a 30-year deal in May 2014 to supply China, the world's largest energy market, with gas through a pipeline for the first time.

Mr. Miller said that the project is now moving into a "key phase" and is being carried out "strictly on schedule".

Gazprom's agreement with China National Petroleum Corporation came during a visit to Moscow by Chinese President Xi Jinping.
