US cancels joint marine drills with South Korea over Iran war-related force constraints

The US Marine Corps formally notified its South Korean counterpart in June that force availability would be constrained for the division-level exercise, known as Ssangyong.

The United States canceled a joint amphibious landing drill scheduled for next month with South Korea, Seoul's Marine Corps said on Monday, after Washington cited constraints on the availability of US forces due to the war in Iran.

The US Marine Corps formally notified its South Korean counterpart in June that force availability would be constrained for the division-level exercise, known as Ssangyong, a South Korean Marine Corps spokesperson told a press briefing.

The allies remain in close consultations on resuming the drills, the spokesperson said. He did not specify what measures might be taken to prevent future cancellations or to make up for lost training opportunities.

US Forces Korea did not immediately respond to a request for comment.

Rubio spoke with the South Korean foreign minister about a 'range of issues'

Later on Monday, the US State Department said that US Secretary of State Marco Rubio had spoken with South Korean Foreign Minister Cho Hyun about a "range of issues" in their alliance.

Rubio told his South Korean counterpart that Washington and Seoul need to remain in close coordination on matters integral to their alliance, according to a State Department statement.

The cancellation of the amphibious landing drill follows US President Donald Trump's surprise order to scale back a separate annual joint military exercise that ended last Friday, citing the cost and Seoul's refusal to take part in the Iran war.

Trump also wrote on his Truth Social platform that the Ulchi Freedom Shield drills sent "a signal that was totally inappropriate and hostile, to a Country that, as long as Donald J. Trump has been President, has been unthreatening and respectful." Despite the reduction of the exercises, Pyongyang fired 10 short-range ballistic missiles last week and issued a statement denouncing the exercises.

North Korea has long condemned such joint exercises as rehearsals for invasion.
