Trump said he had formed a "very special bond" with Kim and that relationship with North Korea would be very different. "Kim must not see American weakness". He continued to tweet angrily at Trudeau from Singapore, saying Monday "Fair Trade is now to be called Fool Trade if it is not Reciprocal".
USA and North Korean officials huddled throughout Monday at the Ritz-Carlton hotel, outlining specific goals for what the leaders should try to accomplish and multiple scenarios for resolving key issues, a senior U.S official said, adding that the meetings were also an ice breaker of sorts, allowing the teams to get better acquainted after decades of minimal contact between their nations. U.S. officials have already established a contingency plan for a two-day summit should the two leaders agree to an immediate second-round of talks.
While the U.S.is ultimately hoping to make progress on denuclearization, North Korea is reportedly looking to gain security assurances, something U.S. Secretary of State Mike Pompeo told reporters on Monday the administration is open to giving them - under the right conditions.
Trump said earlier the Tuesday summit with Kim on a Singapore resort island could "work out very nicely" as officials from both countries sought to narrow differences on how to end a nuclear stand-off on the Korean peninsula. But U.S. officials have since avoided such lofty declarations.
Asked whether he would invite Kim to the White House, Trump said: "Absolutely, I will". One of the diplomats interrupted me politely and said: "You miss the point".
The discussions between the United States and North Korea are ongoing and have moved more quickly than expected.
His abrupt change of schedule will see him leave Singapore about 8pm on Tuesday (local time) after a full day of meetings with Kim, nearly 15 hours earlier than previously anticipated.
Michael Kovrig, a senior adviser for northeast Asia at the International Crisis Group, said Pompeo's comment that Trump "recognised Chairman Kim's desire for security" signalled that the U.S. may offer formal security guarantees to Pyongyang in exchange for nuclear disarmament.

The former Conservative prime minister said that while he believes the dispute is serious, that doesn't make it "lethal". Tagging President Trump , he tweeted: Others just took the opportunity to laugh.
Kim apparently takes a portable toilet with him everywhere he goes, preferring not to use public restrooms. The meetings also served as an ice breaker of sorts as the teams worked to get better acquainted after decades of minimal U.S.
Now, Trump plans to hold his first meeting with Kim alone save for a pair of interpreters, heightening concerns he will stray from the approach United States officials hope the President will follow.
Trump responded to such commentary on Twitter, saying: "The fact that I am having a meeting is a major loss for the USA, say the haters & losers".
Such treats are unheard of for most North Koreans, even for government officials, who have seen their chances of overseas travel wither in recent years as their country's isolation has increased under sanctions imposed over its nuclear and missile programs.
Kim has offered to deal away his nuclear arsenal but doubts remain over whether he is truly willing to give up his nukes or is using the summit to weaken US -led sanctions against his country.
In a tweet on June 1, the scholar said, "This is the only way to advance if we are to avoid catastrophic failure of diplomacy or catastrophic success, ie, offering up too much to get a deal in Singapore".
"I think we should take some optimism from that reporting", a White House official told ABC News.
