A U.S. envoy is due to visit South Korea on Wednesday, officials said, as Washington and Pyongyang struggle to find a breakthrough in their stalled talks aimed at ending North Korea’s nuclear programme.
Stephen Biegun, the U.S. special representative for North Korea, is due to stay four days, a diplomatic source told Reuters.
North Korean leader Kim Jong Un vowed to work towards denuclearisation at his landmark summit with U.S. President Donald Trump in Singapore in June but the two sides have since made little progress.
They have yet to reschedule talks between U.S. Secretary of State Mike Pompeo and senior North Korean official Kim Yong Chol after abruptly cancelling a meeting in November.
Trump has said a second summit with Kim is likely to take place in January or February, though he wrote on Twitter last week that he is “in no hurry”.
North Korea has for years pursued nuclear and missile programmes in defiance of U.N. Security Council resolutions but the bellicose rhetoric from both Pyongyang and Trump that raised fears of war has eased this year.
