North Korea's leader condolences on the departure of his mother, President Moon Jae-in, a Green House spokesman said today.

Mr. Kim sent a letter through the Panmunjom area at the border last October 30, expressing "deep sympathy and condolences" to President Moon's loss to the death of his mother, Kang Han- ok, South Korean Presidential spokesman Ko Min-jung said at today's briefing.

Ms. Kang died on October 29 at a hospital in the port city of Busan, South Korea, at the age of 92.

The message of condolence North Korea's leader sent to the South Korean President in the context of the process of denuclearization between Pyongyang and Washington is still stalling.

North Korea has recently intensified criticism of South Korea for joint exercises with the United States, which use high-tech weapons that Pyongyang thinks are designed to counter threats from North Korea.

North Korean leaders last week ordered the demolition of a Korean-built resort on Mount Kumgang and rebuilt in a more modern way using the Korean method. During a visit to the resort on the east coast of North Korea, Kim said that viewing Mount Kumgang as a symbol of inter-Korean relations is a "misconception".

He also emphasized that this tourist spot is located on the territory of Korea, so it cannot be controlled by Korea. Mount Kumgang has long been a symbol of cooperation between Pyongyang and Seoul.

Kim Jong-un in June sent his sister to Seoul and sent flowers to visit when the late Korean president Kim Dae-jung's wife, famous for his "Sunshine Policy" and steadfastly promoted dialogue in the two Koreas, died.
