North Korean leader Kim Jong Un is willing to hold talks with Prime Minister Shinzo Abe, South Korea's presidential Blue House said Sunday, just days after a historic North-South summit.

Kim told South Korean President Moon Jae-in during Friday's talks that he is ready to hold a dialogue with Japan at "any time," the Blue House said, adding that Moon had relayed Kim's remark to Abe in a telephone call Sunday morning.

Abe told Moon that Tokyo intends to work to hold a bilateral summit with Pyongyang, adding he hopes Moon will mediate if necessary, the Blue House said.
