Russia, S.Korea to sign new gas pipeline deal

MOSCOW, Sept 29 (Reuters) - Russia and South Korea will sign a new deal to supply Siberian gas to Seoul on Monday in a fresh attempt by the two states to unlock a long-delayed pipeline project.

A Kremlin official, who did not want to be identified, told Reuters the deal between state firms Gazprom GAZP.MM and Kogas 036460.KS would be signed during South Korean President Lee Myung-Bak's visit to Russia.

Russia first pledged to supply gas to South Korea at the start of this decade but the project to build a pipeline to China and subsequently to South Korea has been repeatedly delayed.

The delays came as Gazprom struggled to gain control over some of the biggest Siberian deposits to ensure it has enough resources to fill the link. The project is also complicated by the fact that the gas would have to be supplied either via the territory of North Korea or by a more expensive undersea route.
