Canada and Mexico have announced retaliatory measures, while China is turning to the World Trade Organization (WTO), in response to US President Donald Trump’s decision to slap sweeping tariffs on the United States’ largest commercial partners.

Donald Trump says US tariffs on Canada, Mexico, and China are necessary after decades of being "ripped off" by trade partners. Canadian PM Trudeau warned of "real consequences" for American consumers.

Canada’s Prime Minister Justin Trudeau and Mexico’s President Claudia Sheinbaum swiftly hit back at US President Donald Trump’s tariffs with their own actions. Meanwhile, China has vowed to challenge Trump’s tariff move at the World Trade Organization as it 'seriously violates' international trade rules.
