Kim Jong-Un promises transparent nuclear test site closure

North Korean leader Kim Jong Un plans to invite experts and journalists from the United States and South Korea when the country closes its nuclear test site in May, Seoul officials said on Sunday, as US President Trump pressed for total denuclearisation ahead of his own unprecedented meeting with Kim.

On Friday, Kim and South Korean President Moon Jae-in vowed "complete denuclearisation" of the Korean peninsula in the first inter-Korean summit in more than a decade, but the declaration did not include concrete steps to reach that goal.

North Korea's state media had said before the summit that Pyongyang would immediately suspend nuclear and missile tests, scrap its nuclear test site and instead pursue economic growth and peace.

Kim told Moon that he would soon invite the experts and journalists to "open to the international community" the dismantling of the facilities, the Blue House said.

"The United States, though inherently hostile to North Korea, will get to know once our talk begins that I am not the kind of person who will use nuclear weapons against the South or the United States across the Pacific," Moon's press secretary Yoon Young-chan quoted Kim as saying.

"There is no reason for us to possess nuclear weapons while suffering difficulties if mutual trust with the United States is built through frequent meetings from now on, and an end to the war and non-aggression are promised."

Kim said there were two additional, larger tunnels that remain "in a very good condition" at the Punggye-ri test site beyond the existing one, which experts have said had collapsed after repeated explosions, rendering much of the site useless.

Kim's promise shows his willingness to "preemptively and actively" respond to inspection efforts to be made as part of the denuclearisation process, Yoon said.

To facilitate future cross-border cooperation, Kim pledged to scrap the unique time zone Pyongyang created in 2015. He said the North would move its clocks forward 30 minutes to be in sync with the South, nine hours ahead of Greenwich Mean Time.
