President Donald Trump's long-anticipated trade tariffs — which include new import taxes on goods from China, Canada, and Mexico — were made official on Saturday, according to the White House. Trump told reporters earlier in the week that he planned to impose a 25% tariff on goods from Canada and Mexico to strengthen border policy and a 10% tariff on China to crack down on drug imports.

Mr. Trump is trying use tariffs to force Mexico to better guard its border with the United States, but Mexican officials say the tariffs will only hurt both countries.
