North Korean leader Kim Jong-un and US President Donald Trump have shaken hands at the venue for their historic summit on Singapore's Sentosa Island.
The two men shook hands before they met alone with a pair of interpreters for roughly 45 minutes while their entourages wait nearby.
Before a row of alternating US and North Korean flags, the leaders shook hands warmly at the island resort, creating an indelible image of two unorthodox leaders as they opened a conversation that could determine historic peace or raise the spectre of a growing nuclear threat.
Trump and Kim strode out from opposite sides onto a red carpet in front of the flags and after the handshake stood unsmiling in front of waiting photographers, their arms at their sides.
Trump patted Kim on the back as he led him away down a corridor for their one-on-one discussions.
Trump is predicting that he and Kim will have "a terrific relationship" as they meet face to face for the first time.
Trump said he was feeling "really great."
"We're going to have a great discussion and a terrific relationship," he said.
In brief remarks sitting next to Trump ahead of their one-on-one talks, Kim said: "Old practices and prejudices worked against us but we overcame all of them and we are here today."
A live interpreter translated the remarks, made in Korean, for the press.
It is the first-ever meeting of sitting US and North Korean leaders
After the meeting, they are scheduled to hold a larger meeting and working lunch.
Mr Trump's chief of staff, national security adviser and secretary of state are among those expected to join.
