PJSC Gazprom is wrapping up negotiations with China National Petroleum Corp. for the amount of natural gas deliveries from its Power of Siberia pipeline.

"We are negotiating with CNPC to discuss the gas deliveries via the Asian route," Vitaly Anatolyevich Markelov, Gazprom deputy chairman of the management committee and director, said June 15 during a special call.

The Power of Siberia pipeline will transport gas to the domestic Russian market and for export to China. Export negotiations with China National Petroleum are expected to be completed by the end of the year, he added.

Gazprom has completed constructing almost 85% of the linear, or trunk, part of the pipeline, which runs from the Chayandinskoye field to the China border, the company said in a recent news release. At the same time, the second tunnel of the underwater crossing of the pipeline's section through the Amur River was completed.

Deliveries of Russian gas via the pipeline to China should begin in late 2019.
