The United States and South Korea have agreed to indefinitely suspend two exchange program training exercises, the Pentagon said on Friday, in the aftermath of the summit earlier this month between U.S. President Donald Trump and North Korean leader Kim Jong Un.

At a news conference after the meeting with Kim in Singapore, Trump announced that he would halt what he called very provocative and expensive regular Military Exercises that the United States holds with South Korea.

North Korea had long sought an end to the war games. Earlier this week, the United States and South Korea said they were suspending planning for August’s Freedom Guardian exercise. The decision to halt military exercises with South Korea baffled allies, military officials and lawmakers. The drills help keep U.S. forces at a state of readiness in one of the world’s most tense flashpoints.
