It is only a few months since Donald Trump and Kim Jong-un were trading insults and threatening to launch World War Three, yet on Tuesday morning they laid aside the rhetoric and met for the first time.

In a major breakthrough, Mr Trump and Kim signed what the US president said was a "very important" and "pretty comprehensive" joint statement.

Kim declared the "world will see a major change" and that he and Mr Trump had "decided to leave the past behind" as they signed the document.

At a press conference later in the day, Mr Trump said Kim had told him North Korea was destroying a major engine-testing site used for missiles, but maintained international sanctions on Pyongyang would stay in place for now.

Mr Trump said joint military exercises with South Korea would be halted. He said the move would save Washington a tremendous amount of money and would not be revived "unless and until we see the future negotiation is not going along like it should".
