The handshake lasted about 12 seconds.
"China is also the main party that has helped the Trump-Kim summit overcome various issues, allowing it to be finally held", it added. He also said Kim agreed to destroy a "major" missile testing site, but did not offer specific details.
During a brief walk, Trump guided Kim over to his custom Cadillac limousine and gave him a peek inside.
"An unsuccessful summit would be one in which talks break down, leading to renewed and heightened tensions, possibly similar to what was seen in 2017 with harsh words and bellicose actions by both sides".
"It was not easy to get here", Kim said, according to a translator.
The White House said preparatory negotiations had "moved more quickly than expected" and Donald Trump would leave on Tuesday evening after his talks with Kim Jong-un, ruling out the possibility the unprecedented tete-a-tete would run to two days.

The Trump administration seeks a "complete, verifiable and irreversible" dismantlement of Pyongyang's vast nuclear weapons program, which has produced up to 60 nuclear warheads housed across the country, according to U.S. intelligence estimates, as well as a sophisticated program for their delivery worldwide. Kim toured Singapore by night on Monday, enjoying his third known trip out of his country since taking over the regime in 2011. Kudlow's wife, Judy, told the Washington Post that "he's doing fine".
He called Kim "very smart" and a "very worthy, very hard negotiator".
