Russia’s largest gas firm, Gazprom, says it has held separate working-level talks with energy officials from South and North Korea.

The gas giant said Thursday that during talks with a delegation of North Korea’s Ministry of Crude Oil Industry, it signed a memorandum of understanding and agreed to set up a joint working-level group on building a gas pipeline that will run from Russia through North to South Korea. The project is aimed at providing Russia’s natural gas to the South.

Gazprom said during talks with a delegation of South Korea’s state-run Korea Gas Corporation, the two sides adopted a roadmap for the gas pipeline project.

A trilateral meeting between energy officials of the three countries, however, did not take place.
