President Donald Trump imposed tariffs on the United States’s neighbors along with one of its top adversaries and has teased additional tariffs on other countries in a bid to push for action on the fentanyl crisis.

On Saturday, Trump announced his administration would enact 25% tariffs on all products imported from Canada and Mexico — with the exception of Canadian oil, which received a 10% tariff — along with a 10% tariff on imports from China, as the president followed through on months of threats.
