A US special envoy expressed concern Sunday over North Korea's claim to be moving closer to a second way of making nuclear bombs, calling it "another manifestation of the problems" caused by the North's atomic ambitions.
North Korea said Friday its process of enriching uranium is nearly complete, giving the country a new way to make weapons in addition to its known plutonium-based program. The announcement came just hours before Stephen Bosworth, the US special envoy on North Korea, flew to Seoul to discuss how to bring the North back to stalled disarmament talks.
"Clearly, it is another manifestation of the problems posed by North Korea's efforts to acquire nuclear weapons," Bosworth told reporters in Seoul.
"If we are going to deal as we wish with the denuclearization of the Korean peninsula, this is an issue that will have to be clarified," he said.
