SEOUL, South Korea - North Korean leader Kim Jong Un told the South's President Moon Jae-in on Friday he was willing to visit him in Seoul "any time if you invite me", Moon's spokesman said.
Kim made the remarks as the pair chatted ahead of their summit in the Demilitarized Zone that divides the Koreas, the official said.
According to the official, Moon told the visitor he could "show you scenes far better than this if you come to the Blue House", with Kim responding: "Really? I will go to the Blue House any time if you invite me."
Earlier, on the Military Demarcation Line that delineates the border, Moon asked him: "While you come to the South, when can I possibly go over there?"
After stepping over the line and becoming the first North Korean leader to set foot in the South since the end of the Korean War in 1953, Kim responded: "Why don't we just cross over now?" - prompting Moon's unscripted entry into Northern territory.
Later on, Kim said: "The border is not even that high. Wouldn't it disappear if many people keep walking across it?"
Moon expressed hopes that after their summit at Panmunjom, "our meetings will continue at Pyongyang, Seoul, Jeju island and Paektu mountain" -- the island and mountain at the southern and northern ends of the Korean peninsula.
Last year the North carried out a series of missile launches, many of them in the early hours, and its sixth nuclear test, but Kim promised Moon there would be no more.
"I heard that you had early morning sleep disturbed many times because you had to attend the National Security Council meetings because of us," he said.
"I will make sure that your morning sleep won't be disturbed," he added, reiterating a pledge he made when Moon's envoys visited Pyongyang earlier this year.
