SEOUL, Aug. 19 (UPI) — South Korea and the United States will significantly scale down their ongoing Ulchi Freedom Shield joint military exercise, Seoul’s Joint Chiefs of Staff said Wednesday, cutting it short by almost a week following an order by U.S. President Donald Trump.

“South Korea and the United States have agreed to make partial adjustments to the exercise period and scale at the suggestion of the U.S. side,” the JCS said in a statement.

“First, it was decided to adjust the duration of this UFS exercise to run from the 17th to the 21st,” the statement said. “Second, it was decided to conduct the combined field maneuver training on a reduced scale.”

The allies are discussing specific details of the field training reduction, the JCS added.

Ulchi Freedom Shield began Monday and was originally scheduled to run through Aug. 27.

The move comes after Trump called for the drills to be “substantially reduced” in a Truth Social post Sunday, saying they are expensive and “send a signal that is totally inappropriate and hostile” to North Korea.

South Korean Foreign Minister Cho Hyun said Wednesday morning that Seoul was not given advance notice of Trump’s directive.

“Neither our government nor officials within the U.S. government had any prior knowledge of what President Trump revealed on Truth Social,” Cho said at a parliamentary hearing. “Consequently, we were not notified beforehand.”

In his Sunday post, Trump said Pyongyang “has been unthreatening and respectful” while he has been in the White House.

Speaking to reporters in the Oval Office on Monday, Trump touted his personal relationship with North Korean leader Kim Jong Un, saying Kim had “always treated me with great respect.”

“I understand him. He understands me,” Trump said, adding that Kim had responded to his requests for talks but providing no further details.

The Wall Street Journal, citing U.S. officials, reported Tuesday that Trump is pushing aides to arrange a meeting with Kim as soon as this fall, although no official planning is underway. Trump has privately discussed holding talks during his next trip to Asia, which could come in November when world leaders gather for the Asia-Pacific Economic Cooperation summit in Shenzhen, China.

North Korea, meanwhile, has not publicly responded to Trump’s overture. In a commentary published earlier Wednesday, before Seoul announced the reduction, the state-run Korean Central News Agency criticized Ulchi Freedom Shield as “frantic exercises” pushing the Korean Peninsula to the “threshold of a war.”

The commentary threatened that Pyongyang would continue exercising its “right to self-defence” to counter what it called military threats from the allies.

North Korea frequently condemns U.S.-South Korean military drills as rehearsals for an invasion.

Trump similarly called for suspending or scaling back the exercises in his first term, when he pursued direct diplomacy with Kim that included summits in Singapore and Hanoi and a brief meeting at the DMZ.

After the 2018 Singapore summit, Trump surprised observers by announcing that the United States would halt what he called “provocative” joint military exercises with South Korea. That year’s Ulchi Freedom Guardian exercise was canceled, while several subsequent drills were reduced in scale.
