President Donald Trump announced a trade agreement with Japan on Tuesday, making it the largest U.S. trade partner to broker an accord as the White House threatens to impose tariffs on dozens of countries within days.

“Mexico will continue to pay a 25% Fentanyl Tariff, 25% Tariff on Cars, and 50% Tariff on Steel, Aluminum, and Copper. Additionally, Mexico has agreed to immediately terminate its Non Tariff Trade Barriers, of which there were many,” Trump wrote. He did not provide specifics.
