WASHINGTON — The United States and South Korea will suspend two large-scale joint military exercises this spring, two American officials said Friday, as part of President Trump’s efforts to maintain the truce he has struck with Kim Jong-un, the leader of North Korea.

A limited version of the training drills, however, are still expected to go forward, officials said. The United States and South Korea have long held large-scale exercises in the spring, known as Key Resolve and Foal Eagle — the latter of which usually includes thousands of ground, naval, air and special operations troops from both nations.

The decision to scale back the military exercises follows nuclear talks this week between Mr. Trump and Mr. Kim that ended without an agreement on how — or whether — to shut down North Korea’s nuclear weapons program. As the Trump administration continues to seek a resolution, a Defense Department official said, the high-profile missile exercises that Pyongyang views as provocative will be toned down.

The official said the decision to formally suspend the large-scale drills was expected to be announced by the United States and South Korea in the next few days. It was first reported by NBC News.
