US nuclear experts arrived in Beijing on Wednesday on their way to North Korea for talks on disabling the North's main nuclear reactor.
The visit follows a meeting of the two Koreas, the US, China, Russia and Japan in late September in Beijing at which North Korea agreed to disable its Yongbyon complex and declare all its nuclear programs by the end of this year.
The US team leader, top State Department Korea expert Sung Kim, made no comments after arriving at Beijing airport. He is expected to catch the next scheduled flight to Pyongyang on Thursday.
The team, which includes technical experts from various US government departments, will put in place a plan for Yongbyon's disablement, State Department spokesman Sean McCormack said earlier this week.
Other teams would then go to North Korea to carry out those technical steps, McCormack added.
