North Korea often talks of denuclearization, but the United States wants a firm commitment, Stephen Bosworth, a senior U.S. envoy to North Korea, said, the Yonhap news agency reported Monday.
"The U.S. is not interested in talking just for the sake of talking with the North Koreans," Bosworth told reporters after talks with South Korea's chief nuclear envoy, Wi Sung-lac.
"We want negotiations that produce a meaningful result. So we will be looking for indications that North Korea shares that desire and that determination," Bosworth said.
Bosworth said he is optimistic stalled talks with North Korea could resume, and the United States will continue sanctions against it until that happens, the report said.
North Korea has been signaling it might be willing to return to nuclear negotiations, which have been stalled since late 2008; the talks bring together officials from North and South Korea, China, Japan, Russia and the United States.
