It is said that China National Petroleum Corporation (CNPC) is planning to invest in the Russian gas fields. Once accomplished, this investment which is at least 10 billion dollars, will be the largest overseas investment for the company. The analysts said that CNPC's investments into upstream assets ease the future effects coming from the natural gas’ price fluctuation. If the price of natural gas rises, CNPC will be able to cover its loss by sharing the profit of natural gas field.
