The Singapore summit was the first such meeting for a sitting US president/AFP
US President Donald Trump is to meet North Korean leader Kim Jong-un for a second summit by the end of February, the White House says.
The announcement came after Mr Trump met top North Korean negotiator Kim Yong-chol at the White House. He had been expected to deliver a letter from Kim Jong-un to Mr Trump.
Little progress has been made on denuclearisation since their historic summit in Singapore last June. No venue has been announced for the new summit. Speculation is mounting that it could be held in Vietnam, reports BBC.
Kim Yong-chol's visit to Washington is the first sign of movement in nuclear diplomacy with North Korea for months, BBC state department correspondent Barbara Plett Usher reports.
It is not clear what the reported letter from Kim Jong-un contained. But it was expected to lay the groundwork for another summit, our correspondent adds. President Trump said he was looking forward to the talks.
His press secretary Sarah Sanders said after the White House meeting that progress in the talks on denuclearisation continued, but added: "The United States is going to continue to keep pressure and sanctions on North Korea."
