President Donald Trump said he's hopeful that a planned face-to-face meeting with North Korean leader Kim Jong Un will happen, but even if it doesn't the U.S. will be in "great shape."

North Korea threatened Tuesday to cancel the June 12 summit between Kim and Trump in Singapore. Pyongyang stated that it would not entertain a "a one-sided demand" from Trump for the country to give up its nuclear weapons.

The announcement came hours after North Korea canceled high-level talks with South Korea over Seoul's joint military exercises with the U.S.

White House Press Secretary Sarah Sanders said Wednesday that if the meeting doesn't materialize, Trump will continue his "maximum pressure campaign."

"My attitude is, whatever happens, happens. Either way, we're gonna be in great shape," Trump said at the White House on Thursday after meeting with NATO Secretary General Jens Stoltenberg.

He said that if Kim agrees to a deal that would denuclearize the Korean Peninsula, it would be great for Kim and the North Korean people.

"The best thing he could ever do is to make a deal."

He rejected the notion that the Trump administration is using Libya as the model for the talks. 

"We decimated that country. There was no deal to keep Qaddafi. ... This would be something where Kim Jong Un would be there, he'd be running his country. His country would be very rich," Trump explained.

He said China may be "influencing" Kim, noting his recent visit to see President Xi Jinping.
