When the leaders walked towards each other at Sentosa's Capella Singapore hotel's outdoor courtyard, US President Donald Trump was the first to extend his arm to North Korean leader Kim Jong Un, something a host would normally do, said Mr Praveen Nair, a psychologist and senior consultant at Raven Counselling and Consultancy.
Pompeo also held talks with his South Korean and Japanese counterparts Kang Kyung-wha and Taro Kono respectively to further discuss the details of the Singapore summit.
Trump and Kim certainly repeated the broad goals of the United States offering "security guarantees" to North Korea-i.e., promising we won't invade, which we weren't going to do anyway-in exchange for North Korea committing to "denuclearization", meaning getting rid of the nuclear weapons they built after making previous agreements not to build them.
Pompeo says Trump was referring to the fact that for the first time in history, a U.S. president sat down with a North Korean leader.
A statement on Destiny Pictures" website also makes it clear that the firm "Had No Involvement In President Trump NK Summit Video'. "When you take over a country, a tough country, tough people and you take it over from your father - I don't care who you are, what you are, how much of an advantage you have - if you can do that at 27 years old, that's one in 10,000 that could do that. No longer - sleep well tonight!"
It calls for the two countries to jointly work on efforts to build a lasting peace on the Korean Peninsula, to establish new U.S.
But he also said he would love to bring the USA military out of South Korea because of the cost, adding that while it was not now part of the discussion, "at the appropriate time, it will be".
Tokyo has reacted with concern at Trump's plans to cancel military exercises with South Korea, saying such drills are vital for East Asian security.More news: Netflix is dabbling in adding games to its streaming service

Several reporters asked whether Mr Trump had raised the issue of human rights with Mr Kim, who runs a totalitarian regime with extreme censorship and forced-labour camps. "North Korea has great potential for the future!"
He said Pyongyang was committed to giving up its nuclear programme.
Despite Pompeo's insistence that sanctions would hold until denuclearization occurred, he offered few details on how the complex process of complete, verifiable and irreversible denuclearization would be implemented.
Pompeo is expected to meet later with Chinese President Xi Jinping before heading back to Washington.
He says Trump and Kim Jong Un had a "blunt conversation" about changes needed for North Korea to rejoin the world community.
Moon has championed engagement with the North, and the agreement's language on North Korea's nuclear program was similar to what the leaders of North and South Korea came up with at their own summit in April.
Trump also drew criticism for announcing he was ending joint "war games" with South Korea, embracing the frequent North Korean criticism that the exercises are "very provocative". He told reporters that if the US concludes they no longer are, the freeze "will no longer be in effect".
Pompeo agreed, saying "We've seen power when China and the USA work together and don't treat the relationship as a zero sum". The next military exercise is scheduled for August, and in years past, has drawn thousands of troops from the U.S., South Korea and other countries. He said he planned to continue sharing the view with Washington and Seoul.
