MOSCOW (AFP) - The United States has set no timetable with North Korea on its return to nuclear arms talks, a senior US envoy said Monday in Moscow after ice-breaking meetings in Pyongyang. Stephen Bosworth stopped in the Russian capital as part of a lightening tour to brief officials of the countries involved in the stalled nuclear disarmament negotiations with North Korea. As to timelines, we dont have timelines. I would only say that we and our partners in this process very much want to resume our work as soon as possible, he said. We are prepared to do that and I know that other countries are as well. While Bosworth described his talks in Pyongyang as useful, business-like and characterized by candour, he reiterated that the United States has no plans for further bilateral consultations with the North. The US envoys groundbreaking visit to North Korea from December 8 to 10 was the first direct contact between Washington and Pyongyang under the term of President Barack Obama, who pledged diplomacy with US adversaries. The two sides said they had reached a common understanding on the need to resume the six-nation negotiations hosted by China, following the visit. Russias deputy foreign minister Alexei Borodavkin declared Moscow satisfied over the progress in talks, stressing a common stance with Washington. I am satisfied that Pyongyang has reaffirmed its commitment to the declaration of December 19, 2005 on the denuclearization of the Korean Peninsula, which is a fundamental document for the six-party talks, he said. South Korea, China and Japan are the other powers involved in the six-party nuclear negotiations.
