US president Donald Trump has said his planned summit with North Korean leader Kim Jong Un will take place in Hanoi, the capital of Vietnam.

The president tweeted the location on Friday, saying his representatives had just left North Korea after a “productive meeting” on the February 27-28 summit.

Mr Trump added: “I look forward to seeing Chairman Kim & advancing the cause of peace!”

The president had previously announced Vietnam as the summit location, but the city had not been identified.

While in Asia, Stephen Biegun, the US special representative for North Korea, is thought to have discussed specific disarmament steps that Pyongyang could promise at the Vietnam summit and what corresponding measures the United States is willing to take.
