President Donald Trump says the planned Singapore summit with North Korea’s Kim Jong Un could be delayed.
The event had been planned for 12 June but there have been concerns that Kim is not committed to denuclearisation.
The doubts about the session were raised in talks between Mr Trump and South Korean President Moon Jae-in, who came to Washington to urge the US president not to let a rare opportunity with reclusive North Korea get away.
As he addressed the media about the his meeting with Mr Moon, he said: “North Korea in this case is the big one.
“The big topic will be Singapore and the meetings. We’ll have to see what happens and whether or not it happens.
“If it does, that’ll be great. It’ll be great think for North Korea. If it doesn’t. that’s OK too. I think a lot of good things will happen.”
Mr Trump added: “If it doesn’t happen, maybe it will happen later. It may not work out for June 12.”
