President Donald Trump is on the verge of hitting America’s three biggest trading partners with sweeping tariffs, a far more aggressive use of his favorite economic weapon than anything he did during his first term.

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.

The president had promised action, though his team had been in negotiations over how to potentially dial back tariffs.
