The cancelation 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.

The United States cancelled 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.
