The president said he planned to impose tariffs on countries that tax U.S. products. He also paused an action against China, allowing its low-cost products to again enter the U.S. tariff free.

President Donald Trump made good on his promise to impose steep tariffs on America’s three largest trading partners — Canada, China and Mexico — citing a national emergency on the flow of fentanyl and undocumented immigrants into the United States.

Ending tariff exemptions on low-cost packages from China has broad bipartisan support in Washington, and Trump pulled the plug when he raised tariffs on Chinese goods by 10% earlier this week. Goods sent through duty-free packages became subject not only to existing tariffs — 25% for many Chinese products — but also the new 10%.
