The U.S. government has set out plans about canceling a rule that lets companies like Samsung, SK Hynix, and TSMC send special chip-making machines to China without asking for permission each time.

Officials in Washington say they are worried that China is using advanced chips to grow its military and spy systems. They want tighter control over what kind of technology gets into China’s hands. If the U.S. removes the waivers, companies would have to ask for permission for every shipment.

This idea is causing concern in South Korea and Taiwan, where some of the world’s top chip companies are based. They say it could hurt their business and cause delays. These countries want the U.S. to think carefully before making any final decision.

If the rule is changed, companies might have to look for new suppliers or shift parts of their business elsewhere. Some experts believe this move could lead to even more tension between China and the U.S.

For now, the U.S. has not made a final decision, but it’s clear that tech exports will remain a big issue in international business.
