North Korea's Kim Jong Un has given his first timeline to achieve denuclearisation, aiming for the end of U.S. President Donald Trump's first term, and has agreed to a third summit with his South Korean counterpart, Seoul officials said on Thursday.
Kim and South Korean President Moon Jae-in will meet in Pyongyang on Sept. 18-20 and discuss "practical measures" toward denuclearisation, Moon's national security adviser, Chung Eui-yong, said a day after meeting Kim.
The summit could provide renewed momentum to talks over denuclearisation between North Korea and the United States, after Trump cancelled a visit to Pyongyang by his secretary of state last month citing lack of progress.
Kim told South Korean officials his faith in Trump was "unchanged" and that he wanted denuclearisation and an end to hostile relations with the United States before Trump's first term in office ends in early 2021, Chung said.
"He particularly emphasised that he has never said anything negative about President Trump," Chung said.
The remarks represent Kim's first timeline for dismantling North Korea's nuclear weapons programme.
In previous, failed talks, North Korea has said it could consider giving up its nuclear programme if the United States provided security guarantees by removing troops from South Korea and withdrawing its so-called nuclear umbrella of deterrence from the South and Japan.
U.S. officials involved in the latest negotiations have said North Korea has refused to even start discussions about defining "denuclearisation" or other key terms such as "verifiable" and "irreversible", and has insisted the United States must first agree to simultaneous steps to reduce economic pressure.
Chung said Kim had stressed the need for the United States to reciprocate North Korea's initial moves, which have included dismantling a nuclear test site and a missile engine facility.
The U.S. embassy in Seoul said it had no information to share on the matter.
North Korea's official KCNA news agency said Kim told the South's envoys that his "fixed stand" was to turn the Korean peninsula into "a cradle of peace without nuclear weapons, free from nuclear threat".
Chung said Kim showed "frustration over the doubt raised by some parts of the international community about his willingness to denuclearise, and asked us to convey his message to the United States".
"He said he would appreciate that such good faith is accepted with good faith," Chung said. "He expressed his strong will to carry out more proactive measures toward denuclearisation if action is taken in response to the North's preemptive steps."
U.S. officials have previously said they have already made concessions, such as halting joint military exercises with South Korea.
During his meeting with Kim, Chung delivered a message from Trump and will relay comments from Kim to U.S. National Security Advisor John Bolton later on Thursday, Moon's spokesman Kim Eui-kyeom told reporters.
Trump spoke to Moon on the evening before Chung's trip and asked Moon to act as "chief negotiator" between Washington and Pyongyang, the spokesman said.
WHAT HAPPENS FIRST?
Kim and Trump held a landmark summit in Singapore in June, in which they agreed to work toward complete denuclearisation. But negotiations have made little progress, while signs North Korea has maintained work on its weapons have emerged.
Under discussion is whether denuclearisation or declaring an end to the 1950-53 Korean War should come first.
The war ended with an armistice, not a peace treaty, meaning U.S.-led U.N. forces, including South Korea, are technically still at war with the North.
"The United States shouldn't delay any further an end-of-war declaration, which the U.S. president promised at the Singapore summit," the North's official Rodong Sinmun newspaper said in an editorial on Thursday.
U.S. officials have said such a declaration could weaken North Korea's incentive for denuclearisation, and create uncertainty about the purpose of 28,500 U.S. troops stationed in South Korea, a legacy of the three-year war.
U.S. Secretary of State Mike Pompeo visited Pyongyang in July, after which North Korea accused him of making "unilateral and gangster-like demands for denuclearisation" while showing little interest in ending the war.
"Looks like Kim is trying to wash away worries that talks could stall or fail, knowing well that Washington is losing patience," said Koh Yu-hwan, a professor of North Korean Studies at Dongguk University in Seoul.
"Kim also made it clear that he needs some kind of proof Trump has abandoned the U.S.'s hostile policy before moving toward denuclearisation. Kim is trying to prove his sincerity."
