WASHINGTON, U.S. President Donald Trump on Thursday expressed optimism about ongoing negotiations to dismantle North Korea's nuclear weapons program, citing a halt in the regime's testing of nukes and ballistic missiles.

Trump's remarks came at a press conference in Brussels, where he attended a summit of North Atlantic Treaty Organization members, as skepticism persists about the implementation of his denuclearization deal with North Korean leader Kim Jong-un.

"That was an amazing, really an amazing meeting, I thought," he said of his summit with Kim in Singapore last month. "And I really think that we established very good relationships.

"We'll see where it all ends, but there have been no missile tests, there have been no research where there has been. They have blown up a site. I hear they're blowing up another -- missile site," he said.
