North Korean leader Kim Jong-un and US president Donald Trump are to meet in person by May, it has been announced, an extraordinary overture after months of mutual hostility.
News of the meeting was delivered by South Korean officials after talks with Mr Trump at the White House.
They passed a verbal message from Mr Kim, saying the North Korean leader was “committed to denuclearisation”.
Mr Trump hailed “great progress” but said sanctions would remain in place.
South Korea’s President Moon Jae-in said the news “came like a miracle”.
“If President Trump and Chairman Kim meet following an inter-Korean summit, complete denuclearisation of the Korean Peninsula will be put on the right track in earnest,” he said.
China has welcomed the development, saying the Korean Peninsula issue was “heading in the right direction” and calling for “political courage”.
However, correspondents say the north has halted missile and nuclear tests during previous talks, only to resume them when it lost patience or felt it was not getting what it demanded.
The latest announcement came days after the South Korean delegation met Mr Kim in Pyongyang.
