U.S. President Donald Trump on Friday said he received a “beautiful” letter from North Korean leader Kim Jong Un, in which Kim also expressed dissatisfaction with joint U.S. – ROK military exercises.

Trump made the remarks during a 30-minute question and answer sessions on the White House south lawn, telling reporters Kim’s letter was hand-delivered to him on Thursday.

The U.S. president also indicated that he would be open to meeting with Kim again, which would be the fourth between the two leaders.

“I got a very beautiful letter from Kim Jong-un yesterday … I think we’ll have another meeting.
