WASHINGTON — President Donald Trump said Wednesday the US hasn't been notified about the Democratic People's Republic of Korea's threat to cancel his planned summit with Kim Jong-un next month.

The DPRK threatened earlier in the day to scrap the historic summit next month between Trump and Kim, saying it has no interest in a "one-sided" affair meant to pressure the DPRK to abandon its nuclear weapons. Trump maintained that he'll still insist on the country's denuclearization should the summit go on.

"We haven't been notified at all" about the threat, Trump said as he welcomed the president of Uzbekistan to the White House.

He added: "We haven't seen anything. We haven't heard anything. We will see what happens."The warning from DPRK's first vice foreign minister came after the country abruptly canceled a high-level meeting with the Republic of Korea (ROK) to protest US-ROK military exercises that the DPRK has long claimed are an invasion rehearsal.

Press secretary Sarah Sanders said earlier Wednesday that preparations for the summit were ongoing despite the cancellation threat and that Trump is "hopeful" the meeting will still take place.

"If it doesn't we'll continue the maximum pressure campaign that's been ongoing," she told Fox & Friends.

Oregon Democratic Sen. Ron Wyden said he is concerned that talks are "really being oversimplified" by the White House.

"This is not a like condo deal where two people sit down and hash out a number of outstanding issues and then they say 'Well, some lawyers can write it up,'" he said.
