Trump receives new letter from Kim Jong Un

The White House said Thursday that President Donald Trump received a new letter from North Korean leader Kim Jong Un and responded quickly with a letter of his own. The correspondence, following up on their Singapore summit, came amid fresh concerns over Pyongyang’s commitment to denuclearization.

Trump early Thursday tweeted his thanks to the North Korean leader “for your nice letter — I look forward to seeing you soon!’’

The White House did not provide details on the specific content of the letter from Kim, received Wednesday, or of Trump’s reply. White House spokeswoman Sarah Huckabee Sanders said the letters addressed their commitment to work toward North Korea’s “complete denuclearization.’’

Sanders said no second meeting is “locked in’’ as a follow-up to the Singapore summit in June, but they remain open to discussions.

The Washington Post on Tuesday reported that U.S. intelligence officials suspect that North Korea is continuing to build new missiles in the same research facility that manufactured the country’s ballistic missiles capable of reaching the United States.

The Post also reported that North Korean officials have talked about how they plan to deceive the U.S. about the size of their arsenal of missiles and nuclear warheads and facilities.
