The two clasped hands for a long while as they posed for photos in front of a row of US and North Korean flags. According to Trump, it's a "very important" and "pretty comprehensive" document. "We're going to have a great discussion and I think ... it will be tremendously successful", he said. "Just means we get home a little later in the evening", Trump said.
"We may be able to recoup a little bit of that, but I think it is a cost that we're willing to pay and it's our contribution to an worldwide endeavor, which is in our profound interests", he added. "It was discussed at length outside of the nuclear situation".
Kim Jong-un appeared unwilling to use the American pen provided for him as he signed the historic denuclearisation deal with Donald Trump today.
Sanctions on North Korea would remain in place until that happened, Pompeo said on Monday.
After all the chumminess between the two leaders was over, Trump and Kim signed a document stating that Pyongyang would work toward "complete denuclearization" of the Korean peninsula.
Since the 1950-53 Korean War, South Korea has grown into one of the most prosperous countries in Asia, while the isolationist North has suffered a stagnant economy and alarmed its neighbours with its increasingly sophisticated nuclear weapons programme.
The agreement states that Secretary of State Mike Pompeo will be tasked with meeting with a high-level North Korean official "at the earliest possible date to implement the outcomes" of the summit.
It is the first time a sitting United States president has ever met a North Korean leader.
The president fielded questions for more than an hour in his first solo news conference since February of 2017.
"I believed in North Korea", Rodman said. "I may be over my head thinking, but then again." producer Timo Vuorensola said on Twitter. "The other alternative is not a good alternative".
The flamboyant former basketball star added that the Trump White House called to thank him for his unlikely diplomacy.
Rodman, who first traveled to North Korea in 2013 to meet with Kim, said he received death threats as a result of his outreach.
"People are going to be very impressed and people are going to be very happy and we are going to take care of a very unsafe problem for the world", stated Reuters quoting US President Trump. "Thank you very much".
