Seoul/Pyeongchang: North Korean leader Kim Jong Un invited South Korean President Moon Jae-in for talks in Pyongyang, South Korean officials said on Saturday, setting the stage for the first meeting of Korean leaders in more than 10 years.

Any meeting would represent a diplomatic coup for Moon, who swept to power last year on a policy of engaging more with the reclusive North and has pushed for a diplomatic solution to the standoff over North Korea’s nuclear and missile program.

The recent detente, anchored by South Korea’s hosting of the Winter Olympic Games that began on Friday, came despite an acceleration in the North’s weapons programs last year and pressure from Seoul’s allies in Washington.

The personal invitation from Kim was delivered verbally by his younger sister, Kim Yo Jong, during talks and a lunch Moon hosted at the presidential Blue House in Seoul.

Kim Jong Un wanted to meet Moon ‘in the near future’ and would like for him to visit North Korea ‘at his earliest convenience’, his sister told Moon, who had said ‘let’s create the environment for that to be able to happen,’ Blue House spokesman Kim Eui-kyeom told a news briefing.

A Blue House official said Moon ‘practically accepted’ the invitation.

‘We would like to see you at an early date in Pyongyang’, Kim Yo Jong told Moon during the lunch, and also delivered her brother’s personal letter that expressed his ‘desire to improve inter-Korean relations,’ the Blue House said.

The prospect of two-way talks between the Koreas, however, may not be welcomed by the United States.

Washington has pursued a strategy of exerting maximum pressure on Pyongyang through tough sanctions and harsh rhetoric, demanding it give up its pursuit of nuclear weapons first for any dialogue to occur.

‘This is the strongest action yet by North Korea to drive a wedge between the South and the United States,’ said Kim Sung-han, a former South Korean vice foreign minister and now a professor at Korea University in Seoul.Moon asked the North Korean delegation during Saturday’s meeting to more actively seek dialogue with the United States, saying that ‘early resumption of dialogue (between the two) is absolutely necessary for developments in the inter-Korean relations as well,’ the South said.

It said the two sides held ‘a comprehensive discussion ... on the inter-Korean relations and various issues on the Korean peninsula in an amicable atmosphere,’ but did not say whether the North’s weapons program was mentioned.

A visit by Moon to the North would enable the first summit between leaders from the two Koreas since 2007, and would mark only the third inter-Korean summit to take place.
