Responding to a reporter's question on the subject, the secretary of state added that the U.S.is "prepared to take actions that will provide [North Korea] sufficient certainty that they can be comfortable that denuclearization isn't something that ends badly for them". Trump then directed Kim to walk down a hallway, where they briefly spoke. "I also think I'll know if it's going to happen fast - it may not, but I'll know pretty quickly whether or not in my opinion something positive will happen". "We will have a terrific relationship".
Rodman grew emotional in the interview as he recalled former President Barack Obama failing to take him seriously when he returned from Pyongyang with a message from Kim after one of his trips.
North Korea, however, has shown little appetite for surrendering nuclear weapons it considers vital to the survival of Kim's dynastic rule.
Mr Trump said the pair had made "a lot of progress".
The meeting marks the first ever meeting between a sitting North Korean leader and a USA president.
Professor John Hajek from the University of Melbourne's School of Languages and Linguistics said the US President was "doing all the talking" and had the "upper hand" when the two met for their historic meeting.
"We are hopeful this summit will have set the conditions for future successful talks", Pompeo said yesterday evening. "I believe this is a good prelude for peace". "And it's my honor to be involved".
The circus-like atmosphere might be amusing if the stakes weren't so high.
An American president and a North Korean dictator are meeting for the first time. -North Korea summit, is expected to pick up a considerable portion of North Korean leader Kim Jong-un's bills.
The US President is reportedly spending a bit more time with PM Lee today - two hours of talks and a working lunch together with government officials from respective countries, according to Channel NewsAsia.
"It's unbelievable, when I said those things, when I said those damn things, when I went back home I got so many death threats", a tearful Rodman told CNN's Chris Cuomo while wearing a "Make America Great Again" hat.
President Trump said during the signing ceremony that they have "developed a special bond".
But North Korea now deems itself "a nuclear state", and insists the US must end its "nuclear threats and blackmail" as a precondition for denuclearization, according to a statement last month from First Vice Minister of Foreign Affairs Kim Kye Gwan.
Though small, Singapore is also wealthy, and able to shoulder the cost of the historic summit, which would appeal to cash-strapped North Korea. According to Reuters, earlier this month Singapore's Defense Minister Ng Eng commented on Singapore paying for numerous expenses of the sit down between Trump and Kim.
