US President Donald Trump warned Tuesday his landmark summit with Kim Jong Un may be delayed, but insisted the North Korean leader is "serious" about denuclearisation.
Hosting South Korean President Moon Jae-in at the White House, Trump did little to quell speculation about the wavering prospects of a historic first summit between US and North Korean leaders.
"It may not work out for June 12," Trump said of the Singapore meeting, adding in a now familiar non-committal riff "if it does not happen, maybe it will happen later."
"There are certain conditions we want to happen. I think we'll get those conditions. And if we don't, we won't have the meeting."
Politically, Trump has invested heavily in the success of the meeting, and so privately most US officials, as well as outside observers, believe it will go ahead.
But as the date draws near, Trump's divergence from his top aides, the differences between the two sides and the astronomically high stakes are coming into sharp relief.
Success could lead to peace on the Korean peninsula and end the threat of nuclear war. Failure could all but destroy hopes of a peaceful solution to the crisis.
"You never know about deals," Trump said. "I've made a lot of deals. You never really know."
North Korea's willingness to denuclearise - the very basis for the talks - was recently plunged into doubt when the government denounced US demands for "unilateral nuclear abandonment."
