Both men walked to Trump's bullet-proof limousine, nicknamed " The Beast", and looked in at the rear seat, with Trump apparently showing Kim something inside. Moon Jae-in, South Korea's president, said after the meeting had started: "Perhaps the minds of our people are on Singapore".
"For long-time Korea-watchers, seeing the first-ever handshake and meeting between a sitting USA president and North Korean leader is already momentous".
The walkabout occurred less than 12 hours before Kim's potentially world-changing day of diplomacy, when he will become the first-ever North Korean leader to meet with a sitting US President.
Mr Trump's delegation at the luncheon included US National Security Adviser John Bolton, Secretary of State Mike Pompeo, White House Chief of Staff John Kelly and Press Secretary Sarah Huckabee Sanders. "I am hoping for denuclearization and a peace agreement, and also for North Korea's economy to open up".

The historic first meeting between a sitting USA president and and North Korea's leader will take place Tuesday at 9 a.m. when Trump and Kin will meet alone with only translators in the room. "We never knew much about the North Korean regime and it's hard to distinguish what's true and what's false".
But he added: "In the end, that doesn't matter".
"I think that very quickly I'll know that something good is going to happen", Trump said in Canada where we met leaders of other G7 economies.
South Korean news agency, Yonhap reported that Kim said in English, "Nice to meet you, Mr. President".
They shook hands for several seconds, Trump reaching out to touch the North Korean leader on his right shoulder.More news: Microsoft's E3 2018 conference shows that Xbox is (sort of) back

In a statement, the Ministry of Foreign Affairs (MFA) said Mr Trump had also accepted President Halimah Yacob's invitation to make a state visit to Singapore in November to attend the 6th Asean-US Summit and 13th East Asia Summit.
Pompeo spoke as top officials from the two countries continued negotiations in Singapore ahead of the meeting between Trump and Kim. Pompeo held firm to Trump's position that sanctions will remain in place until North Korea denuclearizes - and said they would even increase if diplomatic discussions did not progress positively.
"I've been to North Korea six times".
The two clasped hands for a long while as they posed for photos in front of a row of USA and North Korean flags.
