"We'll have to see," the president told reporters, answering the question whether the meeting with Kim was still on.
Trump noted that North Korea had not notified the US about the cancellation of the Washington-Pyongyang summit slated for June 12.
"No decision, we haven't been notified at all. … We haven't seen anything, we haven't heard anything," he said.
Earlier in the day, White House spokeswoman Sarah Sanders said that Trump's administration was still hopeful that the Singapore summit between the US president and North Korean leader would go ahead as planned on June 12.
Meanwhile, Pyongyang stressed that it was not interested in unilateral demands from the US on denuclearization and would negotiate with Trump only if he is seeking to improve bilateral relations.
