China National Petroleum Corporation (CNPC), China's largest oil producer, will supply 100 million cubic meters more natural gas to Central China's Henan Province next year, besides a guaranteed 1.31 billion cubic meters supply, sources from the Henan provincial government said.

The provincial government has held a talk with CNPC. CNPC wanted Henan to support the construction of two CNPC oil pipelines from Jinzhou in northeast China's Liaoning Province to Zhengzhou in Henan Province, and from Lanzhou in northwest China's Gansu Province to Zhengzhou to Changsha in central China's Hunan Province.

The two parties will sign a strategic cooperation on natural gas supply, pipeline construction and refinery based construction, said sources.
