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 Mr Kim is not committed to #denuclearisation .
The doubts about the session were raised in talks between Mr Trump and South Korean President #MoonJae-in , who came to #Washington to urge the US president not to let a rare opportunity with reclusive #NorthKorea get away.
As he addressed the media about 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, I think, for North Korea. If it doesn't, that's okay 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 12 June."
The warning came as a #UN monitoring group moved to enlist the help of the world's biggest #oil trading #companies to enforce sanctions against the rogue state.
There is a cap on the amount of oil North Korea can import and the coordinator of a panel of experts appointed by the UN Security Council said they were seeking support from the top traders to help implement sanctions
