Trump says talks with North Korea going well ahead of summit

US President Donald Trump said on Tuesday that North Korean leader Kim Jong Un had been "very honourable" and that discussions ahead of a planned meeting between the two leaders were going well.

"We have been told directly that they would like to have the meeting as soon as possible, and we think that's a great thing for the world," Trump told reporters during a meeting with French Prime Minister Emmanuel Macron at the White House.
