U.S. Trade Representative Greer said U.S.-Canada talks failed because Canada sought more.

South Korea’s Marine Corps said on Monday the United States has canceled the joint amphibious landing exercise scheduled for next month, with Washington attributing the move to US force constraints caused by the war with Iran. A Marine Corps spokesman said the two sides are in close talks on resuming the exercise but gave no details on steps to prevent future cancellations or to replace lost training. The cancellation follows President Trump’s unexpected order last Friday to scale back another annual joint exercise, citing high costs and Seoul’s refusal to participate in operations against Iran.

Tehran international relations researcher Mosen Farahani said Washington’s sanctions and blockade are being treated by Iran as acts of war, with the blockade viewed as part of that war and requiring an Iranian response. He said countries including the UAE, Turkey, Iraq and Pakistan have trimmed trade with Iran under US pressure but will not fully sever ties, adding the UAE’s cuts were driven entirely by US pressure. Farahani said Iran adopts a cautious stance and seeks to ensure its positions conform with international resolutions.
