The White House receives mail from Kim Jong Un

North Korea leader Kim Jong Un and U.S. President Donald Trump shake hands at the conclusion of their meetings at the Capella resort on Sentosa Island in Singapore.

The president of the United States, Donald Trump, received a "very positive" letter from the leader of North Korea in search of a second meeting, confirmed the White House.

"The president received the letter from Kim Jong Un. It was a very warm and very positive letter," White House spokeswoman Sarah Sanders told reporters, adding that the message showed "Pyongyang's continued commitment to focus on the denuclearization "on the Korean Peninsula.

"The main objective of the letter was to schedule another meeting with the president, to which we are open and we are already coordinating."

Trump and Kim had a historic summit in Singapore in June.
