The White House did not immediately respond to the latest North-South talks, but White House spokeswoman Sarah Sanders said an advance team of White House and U.S. State Department officials would leave for Singapore on schedule to prepare for a possible summit there.
But North Korean leader Kim Jong Un met with South Korean President Moon Jae-in at the demilitarized zone on Saturday in an effort to maintain good relations between their two nations and discuss the possible summit with the USA, in a meeting that was kept secret until after it happened.
The two leaders met for two hours on the North Korean side of Panmunjom, a "truce village" inside the Demilitarised Zone that separates the two Koreas, said Yoon Young-chan, Moon's spokesman.
At their first meeting on April 27, Moon and Kim agreed to pursue "complete" denuclearization of the Korean Peninsula and to work toward a formal end to the 1950-1953 Korean War.
- Kim agrees on direct (working-level) talks between North Korea and the U.S.to narrow their gap on differing opinions, remove misunderstanding and discuss agenda through working-level talks.
"Kim's main concern is that he needs to be able to have trust that the US will surely ensure regime guarantee after they completely denuclearize", Moon told reporters at the Blue House in a press conference broadcast live Sunday morning.
"While Washington and Pyongyang have expressed their hopes for a summit through published statements, Moon has to step up as the mediator because the surest way to set the meeting in stone would be an official confirmation of intent between heads of states", Hong said.
Although the precise agenda was unclear, it was expected that the two leaders would discuss ways of reducing tensions and denuclearising the Korean peninsula.
A White House team is traveling to Singapore to prep for the June 12 meeting between Kim and Trump.
In an effort to salvage an nearly scrapped summit between North Korea and the United States, South Korean President Moon Jae-in once again played his mediating role to defuse what he called "little difficulties".
"We'll see what happens", Mr. Trump said.
Trump called off the meeting Thursday, but has continued to suggest that the meeting could still occur later - or even on June 12, as had been originally planned. "It was a very nice statement they put out".
Kim's sister Kim Yo Jong also attended the meeting, the Blue House confirmed.
The potentially historic meeting between Trump and Kim was on the verge of collapse amid growing distrust between the two sides.
Moon urged the two leaders to directly talk to each other, saying the conventional method of communication in which the North unleashes torrents of invective against the U.S should be avoided while expressing deep regret about the cancellation.
