Trump threatens new tariffs on Canada, South Korea, and Iran's trading partners

Trump said the U.S. will decertify Canadian-made aircraft and threatened to impose a 50% tariff on them. He also threatened to raise tariffs on South Korean goods to 25% and announced a 25% tariff on countries that do business with Iran, a move that could affect China.

Canada's Prime Minister Carney called the threats bluster and said Canada has no plans for a trade deal with China, though other reports note Canada later agreed to cut tariffs on some Chinese electric vehicles. South Korean officials said they would negotiate with the U.S. and downplayed the immediate impact of the proposed chip tariffs. China announced a record $1.2 trillion trade surplus for 2025 and vowed to protect its interests after the Iran-related tariff threat.
