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, reports BBC.

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, BBC reported.
