Beijing hit back with its own tariffs and export restrictions after being subjected to levies by President Trump. Trade experts said China appeared to aim for minimal short-term harm while showing the range of its possible responses.

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%.

U.S. President Donald Trump on Friday signed an executive order delaying tariffs on de minimis, or low-cost, packages from China until the Commerce Department can confirm that procedures and systems are in place to process packages and collect tariff revenue.
