If Kim's summit with Trump is called off or fails, that would be "a blow to Moon and his engagement strategy and to President Trump, who has credited his own pressure campaign as bringing North Korea to the table", Jannuzi said.
Foreign journalists from the US, China, Russia and the United Kingdom took a chartered plane bound for Wonsan, where a press center will be located, from the Beijing Capital International Airport around 9:48 a.m. Tuesday.
North Korea announced in mid-May that it will publicly shut down the test site located in the country's northern region in a ceremony to which media from South Korea, China, Russia, the United States and Britain will be invited to cover.
"If the North Koreans stiff him, if they sit down and meet with him and try to play him, they're going to regret it". He's going to run this the way he sees fit.

North Korea summit: Pence warns Kim Jong-un not to 'play Trump'
North Korea could build a new site if it decides it needs more testing or could dismantle the tunnels into Punggye-ri's Mount Mantap in a reversible manner.
North Korea is outwardly embracing denuclearization with a showy destruction of a probably meaningless nuclear site, while directly communicating to South Korea and the USA that it won't disarm. CBS News is the only USA broadcast network in North Korea to witness the shutdown of the Punggye-ri site in the northeast of the coutry.
That first changed last week, when it lashed out against the maneuvers, cut high-level contacts with Seoul and threatened to "reconsider" the Trump summit.
"Plan B would be military operations to stop the threat that North Korea represents to us and the world, and I hope we don't go down that road".
However, the improving diplomatic environment has hit a rocky patch, with North Korea threatening to pull out of a summit meeting between leader Kim Jong Un and US President Donald Trump in Singapore planned for June 12. North Korea has rejected unilateral disarmament and given no indication that it is willing to go beyond statements of broad support for the concept of universal denuclearisation.

Hong Min, senior researcher at the Korea Institute for National Unification, said it is North Korea's way of expressing its discomfort toward the US.

But Moon has found common ground with his American counterpart by flattering Trump publicly.
"The North also seems to express its displeasure about South Korea and the USA not taking any measures of good will in response to the North's voluntary action to denuclearize", he said, referring to the North's closure of the Punggye-ri site. That site is in a very mountainous part of the country and we are told we may begin the journey there Tuesday night.

Goldstone testified he immediately told Agalarov he believed the meeting was a bad idea. "He said, 'It doesn't matter. Trump Jr. responded to Goldstone on the chain, "if it's what you say I love it especially later in the summer".
