The United States and North Korea have a "common understanding" on the need to resume stalled nuclear disarmament negotiations, US envoy Stephen Bosworth said yesterday after a visit to Pyongyang.
But Bosworth said it was unclear when the North would return to the six-party forum, which it quit in April, a month before staging its second nuclear test.
His three-day visit was the first official contact between Washington and Pyongyang since President Barack Obama took office in January, pledging direct diplomacy with America's adversaries.
