Analysts say Kim's diplomatic outreach in recent months after a flurry of nuclear and missile tests in 2017 indicates he is eager for sanctions relief to build his economy and the global legitimacy the summit with Trump would provide.
"The White House pre-advance team for Singapore will leave as scheduled in order to prepare should the summit take place", White House Press Secretary Sarah Huckabee Sanders told reporters Saturday morning.
South Korean presidential spokesman Yoon Young-chan said Moon will reveal the outcome of his surprise meeting with Kim on Sunday.
"There is ZERO disagreement within the Trump Administration as to how to deal with North Korea.and if there was, it wouldn't matter", the president wrote on Twitter.
Saturday's meeting between Moon and Kim took place in a grand building on the North Korean side of Panmunjom, a heavily fortified village that lies between the two countries and marks the spot where the armistice ending the Korean War in 1953 was signed. Mr. Trump reiterated Friday night that the U.S.is having "very productive talks with North Korea" and the summit could still take place June 12th. They discussed carrying out the peace commitments they reached in their first summit, as well as Kim's potential meeting with Trump, Moon's office said.
Sorry, NFL owners -- you blew it
The NFL chose not to consult that NFL Players Association before implementing the policy, a move that was met with wide criticism. Players who do come onto the field for the anthems would be required to stand or teams would be fined.
But the latest developments also exemplified how quickly aspirations for successful talks between North Korea and the USA - which remain technically at war - can rise and fall.
The planned closing was previously announced by leader Kim Jong Un ahead of his planned summit with US President Donald Trump next month.
At the heart of the North's negative rhetoric that led Trump to cancel the summit is a fundamental difference of views on the path to denuclearization. "The world, and North Korea in particular, has lost a great opportunity for lasting peace and great prosperity and wealth".
Asked Friday if North Korea was playing games ahead of the summit, the president responded, "Everyone plays games". Trump rapidly tweeted that the statement was "very good news" and told reporters that "we're talking to them now". They very much want to do it. He said Pyongyang was willing "to sit face to face at any time".
The outburst at Mr Pence, issued in the name of a top Foreign Ministry official, comes on the heels of another sharp rebuke of Mr Trump's newly appointed national security adviser John Bolton, and has raised concerns that a major gap has opened between the two sides just weeks before the June 12 summit in Singapore.
Joel Wit, founder of the respected 38 North website that monitors North Korea, said Kim's hand has been strengthened regardless of whether the summit goes ahead because recent weeks have seen him forge connections with Chinese President Xi Jinping, as well as with Russian Federation and South Korea.
It also was unhappy about the North's failure to allow global observers to verify the dismantling of the Punggye-ri test site, the staging ground for all six of its nuclear tests.
