North Korean leader Kim Jong Un has invited South Korean President Moon Jae-in to Pyongyang and is ready to meet soon, Seoul’s Blue House said on Saturday.

It would be the first such summit since 2007, at which then-South Korean President Roh Moo-hyun met with then-DPRK leader Kim Jong Il, and the third since the Korean War.

The invitation was delivered by the DPRK leader’s sister, Kim Yo Jong, during a visit by a high-level North Korean delegation to the Blue House – the first such visit by DPRK officials in eight years.
