US President Donald Trump has said a historic summit with North Korea’s Kim Jong-un next month may be delayed.
He was speaking as he received South Korea’s President Moon Jae-in at the White House to discuss the summit.
Mr Moon is “likely tell President Trump what to expect and what not to expect from Kim”, the South Korean news agency Yonhap reports.
Last week the North said it might cancel if the US insisted on it giving up nuclear weapons unilaterally.
“If it does not happen, maybe it will happen later,” Mr Trump was quoted as saying by AFP news agency at the start of his talks with Mr Moon.
According to Reuters news agency, he said there was a “substantial chance” the summit would not happen in June.
The historic 12 June summit is due to take place in Singapore. It follows a summit between Mr Kim and Mr Moon in April.
North Korea is expected to dismantle a nuclear test site this week as a good will gesture but the demolition may be delayed by bad weather.
