Washington (CNN) President Donald Trump on Wednesday offered a non-committal response to North Korean threats to cancel his planned summit with Kim Jong Un, saying he hadn't received any information that would put the talks in jeopardy.

"We haven't been notified at all, we'll have to see," Trump told reporters in the Oval Office, where he was meeting his Uzbek counterpart. "We haven't seen anything, we haven't heard anything. We will see what happens."

But pressed whether he would still insist upon North Korea's denuclearization as a condition for the talks, Trump nodded yes.

Trump's aides were working Wednesday to determine whether overnight warnings from North Korea might scuttle the highly anticipated summit, even as some in the administration conceded the threats were an expected bump in any dealing with the unpredictable hermit regime.

The tough statements from Pyongyang ended the diplomatic warming that had been leading up to the June 12 encounter between the two men, slated to occur in Singapore. The US administration had no advance warning that a top North Korean official would threaten to call off the talks if joint military exercises with South Korea continue or if the US maintained its insistence that North Korea immediately dismantle its nuclear program.
