BEIJING - Gas import from Russia via the western route will hit 30 billion cubic meters per year and last for three decades, according to China National Petroleum Corp (CNPC) on Thursday.

CNPC signed a framework agreement with Gazprom on Nov 9 detailing the natural gas import arrangement.

The deal is another step forward in gas cooperation, preceded by the two oil giants inking a purchase and sales contract on gas import via the eastern route in May, 2014.

CNPC also signed a cooperation agreement with Rosneft on the Vankor Oilfield project on the same day, which defined the trade principles and other terms for CNPC to purchase part of the share stakes of Vankorneft, a Rosneft subsidiary with production of 22 million tons in 2013.

Meanwhile, CNPC said Thursday that gas imports from Myanmar had totalled 3 billion cubic meters by Nov. 11 via the China-Myanmar natural gas pipeline.
