WASHINGTON - US President Donald Trump said on Tuesday his scheduled meeting with the top leader of the Democratic People's Republic of Korea (DPRK) Kim Jong-un may be delayed.

"It may not work out for June 12," Trump told reporters at the White House, referring to the expected date for his meeting with Kim in Singapore.

The DPRK warned last week that Pyongyang would have to reconsider whether to attend the Singapore meeting if the United States "only wants to press the DPRK to abandon its nuclear arsenal."

Pyongyang suspended inter-Korean talks last Wednesday to protest a large-scale US-ROK air drill, and urged the ROK to stop its joint military drills with the United States.

Both the White House and the US State Department said last week that they will continue to prepare for the meeting between President Trump and the DPRK's top leader Kim.
