Trump orders cutting back military exercises with South Korea

US President Donald Trump on Sunday instructed the Pentagon to "substantially reduce" joint military exercises with long-term Asian ally South Korea, citing the cost of the drills and Seoul's refusal to take part in actions against Iran.

Hours before exercises were scheduled to begin, Trump said on his Truth Social site he was "not happy" that the U.S. had agreed to participate and highlighted his "very good relationship" with Kim Jong Un, the leader of nuclear-armed and heavily sanctioned North Korea.

"These exercises are not only costly... but send a signal that is totally inappropriate and hostile, to a Country that, as long as Donald J. Trump has been President, has been unthreatening and respectful," Trump wrote.

The annual Ulchi Freedom Shield joint military exercises are scheduled to run until August 27, with about 18,000 South Korean military personnel participating.

South Korea's Joint Chiefs of Staff told Reuters the drills started on Monday as scheduled. South Korea's presidential Blue House said it was reviewing Trump's post and "hopes that the friendly relationship between the U.S. and North Korean leaders will lead to meaningful dialogue between the two countries, opening discussions aimed at advancing peace and stability on the Korean Peninsula," it said.

The allies would continue coordinating on their combined defense posture and military exercises, it said.

Responding to Trump's claim that President Lee Jae Myung had refused to join U.S. efforts to denuclearise Iran, it said Seoul was discussing potential military contributions, while considering its defense readiness on the Korean Peninsula and domestic legal procedures. Reuters
