President Trump will not participate in a June 12 summit with North Korean leader Kim Jong Un, the White House announced Thursday, citing recent public remarks from the authoritarian nation’s leaders.

“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,” Trump wrote in an open letter to Kim. “Therefore, please let this letter serve to represent that the Singapore summit, for the good of both parties, but to the detriment of the word, will not take place.”
