Russia has supplied 50,000 tons of fuel oil to North Korea in line with a six-nation deal to resolve the country's nuclear problem, state-controlled oil company Rosneft said on Wednesday according to RIA Novosti.
A spokesman for the Russian company said: "The last batch was shipped from our tanker to a Korean port yesterday."
The fuel aid to the impoverished Communist state was provided under an agreement reached at an October 2007 round of six-nation denuclearization talks. Similar fuel shipments have already been made by South Korea and China.
South Korea, China, the United States, Russia and Japan have offered Pyongyang a series of economic and diplomatic incentives in return for denuclearization.
