US diplomat leaves N. Korea with records on nuclear reactor activities

A US diplomat left North Korea on Saturday with boxes of documents detailing two decades of activities at the nuclear reactor that has been at the heart of the communist country's nuclear weapons program. Washington plans to scrutinize the technical logs from the Yongbyon reactor to see if the country is telling the truth about a bomb program that it has agreed to trade away for economic and political rewards. Sung Kim, the US State Department's top Korea specialist, returned to South Korea by land across the heavily fortified border after collecting approximately 18,000 secret papers during a three-day visit to Pyongyang. "We have to take them back and see," Kim told reporters without elaborating, according to South Korea's Yonhap news agency.
