President Donald Trump said on Saturday morning, Aug. 10, that he plans to meet with North Korean leader Kim Jong Un “in the not too distant future,” hinting at a third possible summit between the two leaders to discuss denuclearization of the Korean Peninsula.

The president revealed that Kim Jong Un sent a long letter to his office on Thursday, as “a small apology for testing the short range missiles.”

“In a letter to me sent by Kim Jong Un, he stated, very nicely, that he would like to meet and start negotiations as soon as the joint U.S./South Korea joint exercises are over. It was a long letter, much of it complaining about the ridiculous and expensive exercises. It was also a small apology for testing the short range missiles, and that this testing would stop when the exercises end,” President Trump tweeted.

He added, “I look forward to seeing Kim Jong Un in the not too distant future! A nuclear free North Korea will lead to one of the most successful countries in the world!”

President Trump said on Friday, Aug. 9, he has got a “beautiful letter” from Kim Jong Un, touting his relationship with North Korean leader.

President Trump said Kim wrote in his letter that he was unhappy with the ongoing U.S.-South Korea military drills, but he also was not happy with their own missile tests.

After North Korea has conducted the recent missile launches, some news media and experts voiced concerns about the potential threat from Pyongyang, but President Trump dismissed the fears. He insisted that those tests did not violate the pledge made by Kim during a summit last year that North Korea would halt intercontinental- and medium-range missiles and nuclear weapons tests while negotiations between the two countries are underway.
