Introduction
The semiconductor war between the U.S. and China is intensifying. In the latest move, China has accused the United States of misusing export controls measures to target its semiconductor chip sector. The tension comes as the Trump administration doubles down on restrictions that directly impact China’s access to critical AI and semiconductor technologies.
This shift could escalate the long-running trade war into a more complex battle over technological dominance.

Background: A Trade War Evolves into a Tech War
The U.S. and China have clashed over trade for years. In 2019, former President Donald Trump blocked Huawei from accessing American chip technology.
This forced the Chinese telecom giant to build its own chip solutions. The Biden administration expanded these restrictions in 2022, targeting advanced AI chips from Nvidia and AMD.
Now, under Trump’s return to office, the U.S. is tightening rules again—this time even banning AI design software sales to China.
China Responds to Latest U.S. Measures
On May 30, 2025, China called out the United States for what it termed “abusive and discriminatory” semiconductor export policies.
Liu Pengyu, spokesperson for China’s U.S. embassy, told NBC News, “China urges the U.S. to stop its erroneous actions and respect the Geneva trade consensus.”
China was responding to Trump’s earlier claim that Beijing had broken a 90-day trade truce signed on May 12, 2025, in Geneva. The truce paused most tariffs between the two countries.
The AI Chip Battle: Huawei and Nvidia in Focus
The new U.S. restrictions block American firms from importing or using Huawei’s AI chips. The U.S. Commerce Department also ordered chip software leaders Synopsys and Cadence to halt sales to Chinese firms.
Nvidia, the world’s top AI chipmaker, revealed this week that the ban on its H20 chip—originally designed to meet 2022 export rules—would result in an $8 billion revenue hit this quarter. The company also disclosed $4.5 billion in unsellable inventory due to the restrictions.
“The U.S. assumed China couldn’t make AI chips. That assumption was wrong,” said Nvidia CEO Jensen Huang on the Q1 earnings call.
Expert Reactions and Market Impact
Economists and analysts are warning that the chip controls may backfire. Restricting China’s access may push it to speed up domestic chip innovation.
China has already invested over $150 billion into building its own semiconductor supply chain.
| Company | Impact of U.S. Controls |
|---|---|
| Nvidia | $8B lost revenue; $4.5B idle stock |
| Huawei | U.S. bans AI chips; focus on domestic design |
| Synopsys & Cadence | Blocked from selling to China |
| AMD | Impacted by previous AI chip limits |
Will This Escalate the U.S.-China Tech War?
Trade experts believe this is no longer just about tariffs or economic imbalance. It’s now about AI supremacy, national security, and global chip leadership.
The U.S. wants to limit China’s access to cutting-edge AI tools. China wants to stop relying on U.S. tech.
A full decoupling of the semiconductor ecosystem would hurt both countries—and global tech firms.

Conclusion
Semiconductor export controls have become a new flashpoint in U.S.-China tensions. With both nations doubling down on chip sovereignty, the world may see a divided tech future.
As AI and semiconductors power everything from smartphones to national defense systems, this chip war could define the next decade of geopolitics.
