Moon said that North Korean leader Kim Jong Un on Wednesday agreed to permanently dismantle his main nuclear complex at Nyongbyon if the United States takes corresponding measures, as the two leaders met in in the North Korean capital Pyongyang to try to keep nuclear diplomacy alive with Washington, which has been pushing hard for stronger disarmament moves from the North.
