ADVERTISEMENT Trump told reporters as he left the White House for a fundraiser in the Hamptons that the two men could meet again in the future to discuss denuclearization.

"I think we'll have another meeting," Trump said. "He really wrote a beautiful, three-page -- I mean, right from top to bottom -- a really beautiful letter. And maybe I'll release the results of the letter, but it was a very positive letter."

Trump and Kim have held three face-to-face meetings that have yet to yield concrete plan to denuclearize the Korean Peninsula.

North Korea has in recent weeks launched several test missiles, which watchdogs say violates a United Nations treaty.

Trump has downplayed the tests, insisting he has a strong personal relationship with Kim.
