China’s newest restrictions on rare-earth materials would mark a nearly unprecedented export control that stands to disrupt the global economy and threaten the supply chain for semiconductors, writes The Wall Street Journal (Oct. 10, 2025). Chips are the lifeblood of the economy, powering phones, computers and data centers needed to train artificial-intelligence models. The rule also would affect cars, solar panels and the equipment for making chips and other products, limiting the ability of other countries to support their own industries. China produces roughly 90% of the world’s rare-earth materials.

Global companies that sell goods with certain rare-earth materials sourced from China accounting for 0.1% or more of the product’s value would need permission from Beijing, under the new rule. Tech companies will probably find it extremely difficult to show that their chips, the equipment needed to make them and other components fall below the 0.1% threshold.
“These rare-earth minerals and the ability to refine them are just the basis of modern civilization,” said one industry expert. “It’s an economic equivalent of nuclear war—an intent to destroy the American AI industry,” added a second. The U.S. and other countries are pouring hundreds of billions of dollars into data centers, making AI a key economic engine. China gaining control of the technology would potentially let it catch up in the AI race and upend the world order.
The semiconductor supply chain is vulnerable to actions like China’s because large chip plants require big capital investments from an ecosystem of companies providing specialized equipment, intricate technical processes and final packaging. Companies in the U.S., Taiwan, Japan and the Netherlands all collaborate with one another.
The Trump and Biden administrations have offered subsidies and other policies to aid the process, but domestic capacity generally remains in its infancy. Some analysts said the new rules will fuel new urgency for big tech companies to invest more in these areas.
