U.S. President Donald Trump has received a letter from North Korean leader Kim Jong-un this week,... in what may be the latest sign of top-level diplomacy on Pyongyang's denuclearization.
The White House also says the U.S. is open to a second Kim-Trump summit.
Lee Seung-jae reports.
The White House on Thursday confirmed that,... U.S. President Donald Trump received a letter from North Korean leader Kim Jong-un earlier this week.
White House press secretary Sarah Huckabee Sanders confirmed the news of the letter,... adding that "the ongoing correspondence between the two leaders is aimed at following up on their meeting in Singapore and advancing the commitments" made in their joint statement back in June.

"He did receive a letter, I believe he received it on August 1st. (cut) We have responded to Chairman Kim's letter, the president has, and that letter will be delivered shortly. Beyond that, I can't get into any further details. I can say that the letters addressed their commitment from their joint statement that was made at the Singapore summit and they're going to continue working towards complete and total denuclearization."

This comes as the U.S. leader mentioned the letter in a tweet earlier Thursday,...
thanking Kim for the (quote) "nice letter".
Trump also thanked the North Korean leader for sending home the remains of the American soldiers killed during the Korean War,... and added that he looks forward to seeing him soon.
Last Friday,... coinciding with the anniversary of the signing of Armistice Agreement,... North Korea returned the remains of 55 American soldiers.
While it's hoped that the repatriation will build momentum toward North Korea's nuclear disarmament,... many say the progress towards securing a firm commitment from Pyongyang has been slow.
Meanwhile, the U.S. says it is open to discussions about a second meeting between Trump and Kim,... although nothing has been planned yet.
In a regular press briefing on Thursday,... the White House press secretary said a second meeting has not been "currently locked in or finalized",... but added that the White House is open to that discussion.
Sanders also reaffirmed the U.S's firm commitment on the UN sanctions on North Korea,...
while mentioning that Trump will not be satisfied until a complete denuclearization.
Trump has previously said that he would be open to inviting Kim to Washington, while there is also talk of a possible meeting on the sidelines of the UN General Assembly in September.
