Trump has long proposed raising tariffs—or taxes on imported goods that the businesses importing them pay the U.S. government—before the election, and said in November he’ll impose a 25% tariff rate on all imports from Mexico and Canada on the first day of his presidency and will impose an additional 10% tariff rate on all imports from China on top of other tariffs.

Some of the purported concessions that led to a 30-day pause on the tariffs were things Canada and Mexico had already done before Trump’s threat, but it’s complicated.
