But it is willing to abandon the programs if its national security — and that of its leadership — is guaranteed, Chung said.
That remains a high threshold — Pyongyang has considered itself at risk of invasion by the United States since the Korean War ended in a ceasefire in 1953, leaving the two technically still at war.
But Chung said Kim is willing to discuss denuclearization with Washington — a crucial concession that could enable a dialogue.
Washington has long insisted Pyongyang take concrete steps towards denuclearization as a precondition.
“Whichever direction talks with North Korea go, we will be firm in our resolve,” Pence said.
“The United States and our allies remain committed to applying maximum pressure on the Kim regime to end their nuclear program,” he said. “All options are on the table and our posture toward the regime will not change until we see credible, verifiable, and concrete steps toward denuclearization.”
Tuesday’s developments are the latest steps in a rapid Olympics-driven rapprochement on the peninsula. They follow a year of high tensions during which Pyongyang carried out its most powerful nuclear test to date, along with launches of rockets capable of reaching the US mainland.
Trump has dubbed Kim “Little Rocket Man” and boasted about the size of his nuclear button, while the North Korean leader called the American president a “mentally deranged US dotard.”
But the Pyeongchang Winter Olympics in the South triggered an apparent transformation, with Kim sending his sister to the opening ceremony, sparking a flurry of cross-border trips as South Korean President Moon Jae-in tries to broker talks between Pyongyang and Washington.
North and South agreed to hold a summit in late April in Panmunjom, the truce village in the DMZ, Chung said after leading the most senior delegation to travel North for more than a decade.
It will be the third meeting between the leaders of North and South, but the first to take place in the DMZ after summits in Pyongyang in 2000 and 2007.
The North “made clear that there is no reason to own nuclear (weapons) if military threats towards the North are cleared and the safety of its regime is guaranteed,” Chung said.
Pyongyang “expressed willingness to have frank dialogue with the US to discuss the denuclearization issue and to normalise North-US relations,” he added, and said there would be no provocations such as nuclear or ballistic missile tests while dialogue was under way.
“Also, the North promised not to use atomic weapons or conventional weapons towards the South,” he told reporters, adding that Seoul and Pyongyang would set up a hotline between the leaders.
Kim also said he would “understand” if the South goes ahead with delayed joint military exercises with the US that usually infuriate Pyongyang, a senior official at the South’s presidential office added.
The visit produced “a very important breakthrough,” said Cheong Seong Chang of Sejong Institute think tank, calling the results “an important first step towards stably managing the North’s nuclear and missile threats, preventing war on the Korean peninsula and building political and military trust.”
He cautioned that the definition of “military threats” the North wanted to see removed was “up for interpretation” but said he believed Washington and Pyongyang “would soon begin serious dialogue.”
Previous negotiations have ultimately foundered, however. Six-party talks, grouping the two Koreas, Russia, China, Japan and the US, and offering the North security and economic benefits in exchange for denuclearization, broke down almost a decade ago.
North Korean state media pictures of the delegation’s extended meeting with Kim in Pyongyang showed the North’s leader in a jovial mood, smiling and shaking hands enthusiastically.
“Hearing the intention of President Moon Jae-In for a summit from the special envoy of the south side, he exchanged views and made a satisfactory agreement,” the North’s official news agency KCNA said earlier.
Rodong Sinmun newspaper, the mouthpiece of the ruling Workers Party, devoted its entire front page to the visit.
The trip came after the North’s leader sent his sister, Kim Yo Jong, to the Winter Games, the first visit to the South by a member of the North’s ruling dynasty since the end of the 1950-53 Korean War.
Kim also invited Moon to a summit in Pyongyang but the South Korean leader said the “right conditions” were needed. (With AFP)
