President Donald Trump has pushed into new trade law territory with an emergency sanctions law to justify punishing 25% tariffs on Canadian and Mexican imports and an extra 10% duty on Chinese goods to curb fentanyl and illegal immigration into the U.

Canadian Prime Minister Justin Trudeau and Mexican President Claudia Sheinbaum responded to Trump’s order on Saturday

Elected officials warned that building materials, fuel, kitchen appliances, and more could all be affected as the prospect of a trade war loomed.

The move likely will trigger retaliation and risk igniting a trade war that could cause broad economic disruption for all countries involved.

President Trump moved to impose stiff tariffs on Mexico and Canada, whose leaders swiftly responded with their own levies, and accused Trump of starting a trade war that would debilitate all three economies.

President Donald Trump signed an executive order Saturday imposing a 25% tariff on imports from Mexico and Canada and 10% on imported Chinese goods, according to multiple reports, reflecting his campaign promises to implement high tariffs, against the views of many economists who believe Trump’s plan would burden everyday consumers.

President Trump announced sweeping tariffs on goods imported from Mexico, Canada and China, sending shocks through the global supply chain and raising fears about consumer costs.
