China will pause exports of critical minerals to the United States in the country’s latest move to counteract President Donald Trump’s tariffs. Trump has set a tariff on China at a hefty 145%, which it has responded to with a 125% reciprocal tariff.

The U.S. granted tariff exemptions on laptops, smartphones, and other items. China called on the U.S. to “completely cancel” its tariffs, saying that the exemptions were a “small step” toward doing so.

However, the Trump administration said the new exemptions are a building block toward future tariffs. “So what [Trump is] doing is he’s saying they’re [high-tech products] exempt from the reciprocal tariffs, but they’re included in the semiconductor tariffs, which are coming in probably a month or two. So these are coming soon,” Commerce Secretary Howard Lutnick told ABC News.

The critical minerals and magnets exports have been halted to create a new regulatory system that could further limit what supplies American companies receive.
