Russia and China will reach an agreement on natural gas supply to China by end of March, Russian media reported Monday, citing Russian deputy prime minister Arkady Dvorkovich.

"Gazprom is actively negotiating export terms with Chinese partners," he said, noting that both parties had achieved substantial progress on natural gas cooperation.

In September 2010, Russian natural gas provider Gazprom and China National Petroleum Corp (CNPC) signed an agreement extending an earlier deal for the annual supply of up to 30 billion cubic meters of Russian gas to China.
