U.S. President Donald Trump on Friday said he received a "beautiful letter" from North Korean leader Kim Jong Un, following the regime's latest missile test to warn against joint military exercises between the United States and South Korea.

"I think we'll have another meeting," Trump told reporters outside the White House. "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 very positive."

North Korea had four rounds of weapons demonstrations in the past two weeks, though Trump dismissed the tests, saying Friday they were just for short-range missiles. He added that Kim wrote in the "very personal letter" that he is not happy with the U.S.-South Korea joint exercises.

"He wasn't happy with the tests, the war games. The war games on the other side with the United States. And as you know I've never liked it either," Trump said. "I don't like paying for it. We should be reimbursed for it, and I've told that to South Korea."

The missiles North Korea tested are able to strike U.S. allies South Korea and Japan as well as U.S. military bases there. But the president said Kim sees a "great future" for North Korea, "so we'll see how it all works out."

He pivoted to say the U.S. has routinely been taken advantage of by foreign countries, including its allies "in many cases more than anybody else." Earlier, he told reporters he hopes South Korea and Japan — which have been locked in an economic feud even during North Korea's weapons demonstrations — would "start getting along."

"You know, they are supposed to be allies. And it puts us in a very difficult position. South Korea and Japan are fighting all the time," Trump said.
