WASHINGTON, May 22 (Xinhua) -- U.S. 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 during his meeting with visiting President of the Republic of Korea (ROK) Moon Jae-in, referring to the date of his planned meeting with Kim.

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 U.S.-ROK air drill, and urged the ROK to stop its joint military drills with the United States.

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