MOSCOW- Russian gas giant Gazprom has begun a feasibility study for its Power of Siberia-2 pipeline project that would pump up to 50 billion cubic metres of natural gas to China per year via Mongolia, the Russian gas producer said.

The plan for the route was first announced years ago. Gazprom currently pumps gas to China via its Power of Siberia pipeline in eastern Siberia.
