Read Donald Trump's Full Letter to Kim Jong Un Canceling North Korea Summit

President Donald Trump penned a full letter to North Korean leader Kim Jong Un Thursday canceling their expected summit in Singapore next month but leaving open the possibility of a meeting in the future.

Trump had planned to meet Kim on June 12, a showdown that would have marked the first time the leaders of the United States and North Korea had met face to face. But the president cited the North's recent comments that complete denuclearization of its regime was not going to part of negotiations.

Trump had previously set some conditions on the North, which included denuclearization talks as well as no new missile tests prior to the summit. Trump received some praise in many political circles for bringing the North so close to talks, but critics challenged Trump for possibly legitimizing Kim's power and questioned if the North was merely biding time to simply continue its nuclear and weapons program.

Trump also appeared to make an apparent threat about the U.S.'s nuclear stockpile, writing: "You talk about you nuclear capabilities, but ours are so massive and powerful that I pray to God they will never have to used." The rhetoric mirrored Trump's previous threats of "fire and fury" toward Kim after the North Korean leader suggested his weapons were capable of hitting the U.S. mainland.

Trump also thanked Kim for freeing three U.S. citizens earlier this month.

Here's the full text of the letter:

Dear Mr. Chairman:

We greatly appreciate your time, patience, and effort with respect to our recent negotiations and discussions relative to a summit long sought by both parties, which was scheduled to take place on June 12 in Singapore. We were informed that the meeting was requested by North Korea, but that to us is totally irrelevant. I was very much looking forward to being there with you. Sadly, based on the tremendous anger and open hostility displayed in your most recent statement, I feel it is inappropriate, at this time, to have this long-planned meeting. Therefore, please let this letter serve to represent that the Singapore summit, for the good of both parties, but to the detriment of the world, will not take place. You talk about your nuclear capabilities, but ours are so massive and powerful that I pray to God they will never have to be used.

I felt a wonderful dialogue was building up between you and me, and ultimately, it is only that dialogue that matters. Some day, I look very much forward to meeting you. In the meantime, I want to thank you for the release of the hostages who are now home with their families. That was a beautiful gesture and was very much appreciated.

If you change your mind having to do with this most important summit, please do not hesitate to call me or write. The world, and North Korea in particular, has lost a great opportunity for a lasting peace and great prosperity and wealth. This missed opportunity is a truly sad moment in history.

Sincerely yours,

Donald J. Trump

President of the United States of America
