A day after China orchestrated a six-nation accord on ending North Korea's nuclear program, Pyongyang said it would not dismantle its Yongbyon nuclear facility until it receives nuclear reactors from the US to generate power, a request the US had already rejected, the AP reported. Both the US and China downplayed Pyongyang's comments. In the agreement, North Korea agreed to end its nuclear program in return for aid and security assurances. The deal also committed North Korea to developing closer ties with South Korea and Japan. Despite Pyongyang's demands, the agreement is a major success for China in cutting a foreign policy deal with Washington and in proving its diplomatic capabilities in East Asia.
