North Korean leader Kim Jong-un and South Korean President Moon Jae-in are holding their third summit in September to discuss nuclear disarmament, Seoul said Thursday. From 18 to 20 September, the two leaders will discuss issues such as "practical steps" to denuclearize the peninsula, Chung Eui-yong, National Security Advisor to the South Korean Head of State, told reporters. The dates of the meeting were completed yesterday during a visit to Pyongyang by Mr. Chung, who handed a letter from Mr. Moon to the North Korean leader. Denuclearization Kim Jong-un said he was prepared to cooperate with Seoul as with Washington on denuclearization, continued the South Korean envoy. Kim "has expressed strong commitment to the denuclearization of the Korean peninsula and the intention to work closely with the United States (…) to achieve this goal," said the South Korean envoy. At a historic summit in Singapore on 12 June, US President Donald Trump and Kim Jong-un reached a very vague compromise in favor of a "full denuclearization of the Korean peninsula" whose terms and timing had been postponed to follow-up negotiations. This promise was far from the original American goal of a "complete, verifiable and irrevocable denuclearization". Slow negotiations But the follow-up negotiations between Washington and Pyongyang have skated for weeks, as illustrated again. the surprise cancellation last month by Donald Trump of a new trip to North Korea by his secretary of state Mike Pompeo.
