The North Korean leader's younger sister has met with South Korean officials to convey condolences and give flowers after the recent death of a former first lady.
They met at the truce village of Panmunjom on Wednesday afternoon.
In his message, Kim Jong Un praised the efforts for peace on the Korean Peninsula by Lee Hee-ho who died on Monday. She was the wife of former president Kim Dae-jung.
South Korean National Security Office chief Chung Eui-yong, who led the delegation, told reporters that the sister, Kim Yo Jong, said that they want to continue inter-Korea cooperation, based on Lee's will for the reconciliation and cooperation of the Korean people.
Lee and Kim Dae-jung visited Pyongyang in 2000 for the first-ever inter-Korean summit. Kim was awarded the Nobel Peace Prize that year and died in 2009.
Since the failure of the US-North Korea summit in Hanoi earlier this year, the 2 Koreas have had little contact.
It's still unclear if the meeting could lead to the resumption of talks. The South Korean government says there was no personal message from Kim Jong Un to President Moon Jae-in.
