Gazprom Neft is in the signing phase of a contract to deliver oil products to Afghanistan, the company said.
Under the agreement, Gazprom Neft would supply Afghanistan's state oil company with 10,000 tons of light diesel fuel in September.
TNK-BP is currently one of the biggest oil-product suppliers to Afghanistan. "By steadily increasing delivery volume, we are maintaining our leadership position," a company spokesman said without specifying specific supply volumes.
Russian Energy Minister Sergei Shmatko and Afghan Commerce and Industry Minister Anwarul Haq Ahadi signed a memorandum of mutual understanding on fuel and energy cooperation earlier this month.
The parties agreed on additional oil product shipments by Russian companies of 500,000 tons to help Afghanistan meet its annual need of 3 million tons.
