US President Donald Trump says his second summit with North Korean leader Kim Jong-un will be held in the Vietnamese capital Hanoi.
The two men will meet on 27-28 February for talks expected to focus on persuading the communist state to give up its nuclear weapons programme.
Modern relations with Vietnam are seen as a model for US ties with the North.
A US envoy held “very productive” talks with the North to prepare for the new summit, Mr Trump said.
