North Koreans got their first big dose of news Monday that their leader Kim Jong Un had arrived in Singapore for what even the state-run media was calling a historic meeting with U.S. President Donald Trump.
While on-route to Singapore on Air Force One, Trump took to Twitter to slam Canadian prime minster Justin Trudeau for being "meek and mild" during the G7 meetings and proceeded to also call the latter "dishonest and weak".
President Donald Trump and DPRK leader Kim Jong Un converged on this island city-state Sunday ahead of one of the most unusual and highly anticipated summits in recent world history, a sit-down meant to settle a standoff over Pyongyang's nuclear program.
The US wants North Korea to give up its nuclear weapons but it is not clear what Pyongyang might want in return.
The Flightradar24 website also showed that there were no civilian planes anywhere near Kim's flight, despite it passing through a usually busy area for such aircraft.
Lee is due to met Kim later on Sunday and Trump on Monday.
Earlier, Trump tweeted it was "great to be in Singapore, excitement is in the air". We will have seen each other. Pyongyang says it hopes for a "new" start with the US. Trump canceled the summit last month after both sides exchanged criticism but then revived the summit after tensions cooled.
Final preparations under way for Trump-Kim summit
The White House said the daylong summit would also include a working lunch and a larger meeting involving aides to both leaders. It will take place after some tension, when the nations exchanged insults, and Trump famously called Kim " little rocket man ".
The meeting was Trump's only scheduled public event today.
Trump and Kim will meet on Tuesday at 9 a.m. for talks on denuclearization.
Mr Trump's supporters have floated the idea that forging such a treaty, which would need a sign-off from China and South Korea, would deserve the Nobel Peace Prize. "That's a tough position".
A Trump administration official, speaking on condition of anonymity, said the USA side was entering the talks with a sense of optimism and an equal dose of scepticism given North Korea's long history of developing nuclear weapons.
Under Kim, Pyongyang has made rapid progress in its weapons technology, carrying out by far its most powerful nuclear test to date previous year and launching missiles capable of reaching the USA mainland.
The White House has claimed credit for bringing Mr Kim to the table through a concerted campaign of tough economic sanctions, diplomatic efforts and the threat of military action.
It was reported that Kim planned to fly back to North Korea in the early afternoon on Thursday, leaving very little time for actual negotiations, although there is still considerable uncertainty about what a deal between the leaders would look like. Moon later proposed a tri-lateral meeting to put a formal end to the Korean war after the summit.
Victor Teo, professor at the University of Hong Kong, believes "North Koreans are upbeat, but careful at the same time".
Trump is also on his way to Singapore from Canada after attending the Group of Seven leaders' meeting in Quebec.
