The United States has approved a six-nation agreement in which North Korea plans to disable its nuclear facilities in return for energy aid.
A State Department spokesman Sean McCormack on Tuesday announced that the United States conveyed its approval of the draft agreement to the Chinese government.
North Korea is to disable its nuclear facilities by the end of the year in exchange of more than 900-thousand tons of heavy fuel oil.
It had tested a nuclear weapon last year, but agreed in principle last February to abandon its nuclear program. North Korea shut down its main nuclear facilities at Yongbyon in July.
Yonhap News Agency quotes North Korean envoy Kim Kye-Gwan as saying the United States is considering taking Pyongyang off its terrorist list.
