North Korean leader Kim Jong-un has received a personal letter from US President Donald Trump, according to state media.
Mr. Kim praised the letter as "excellent" and said he would "seriously consider the interesting content," the news agency KCNA said.
He also praised Mr. Trump's "extraordinary courage."
Earlier this month, Mr. Trump said the North Korean leader had sent him a nice letter.
It was not disclosed when and how Mr. Trump's letter was sent to Mr. Kim. The White House has not commented.
Talks between the US and North Korea have come to a standstill after a meeting between Mr. Kim and Mr. Trump ended in February in Vietnam without agreement.
This is the first significant development between countries In the months since Mr Trump and Mr Kim failed to reach an agreement.
However, the two leaders have exchanged a number of letters. The US President described the latest dispatch from Pyongyang as beautiful.
The moment is also remarkable as Donald Trump will visit Seoul next week to hold talks with South Korean President Moon Jae-in.
The US had insisted that North Korea abandon its nuclear program, while Pyongyang demanded sanctions relief.
In recent months, however, Mr. Trump has talked at length about Mr. Kim.
Earlier this month, he told reporters that North Korea, under the leadership of Mr. Kim, had "tremendous potential."
And in May during a visit to Japan, Mr. Trump described Mr. Kim as a "very smart guy" and said he expected "many good things" from North Korea.
