The United States has imposed sweeping new restrictions on exports to China, targeting critical technologies and materials vital to the country’s semiconductor, aviation, and industrial sectors. The move, confirmed by three sources familiar with the matter, adds a fresh layer of tension to the already strained U.S.-China trade relationship.
The U.S. Department of Commerce has ordered multiple American companies to halt shipments of key products to China unless they obtain new export licenses. Existing licenses for some suppliers have also been revoked, affecting industries ranging from semiconductor design to chemicals and machine tools.
The products under the new restrictions include electronic design automation (EDA) software used in chip development, specialty chemicals for semiconductor manufacturing, butane and ethane, advanced machine tools, and aviation components. These goods are considered strategic due to their importance in China’s high-tech and defense-related industries.
Companies that develop EDA software, including Cadence Design Systems, Synopsys, and Siemens EDA, were among those directly affected. Two sources indicated that Cadence and Synopsys received letters last Friday notifying them of the new licensing requirements. While Synopsys CEO Sassine Ghazi said the company had not yet received formal communication from the Commerce Department, the firm acknowledged awareness of the situation and reaffirmed its 2025 revenue forecast.
“This action targets real choke points,” said a former Commerce Department official, noting that curbs on EDA exports had been considered since the Trump administration but were previously deemed too aggressive. China depends heavily on U.S. EDA tools to design cutting-edge chips, and the latest measures could significantly disrupt the country’s chip development pipeline.
The Commerce Department stated it is reviewing exports “of strategic significance to China” and, in some cases, has suspended or modified license terms while that review is underway. However, officials clarified that requests to ship affected products to China will be evaluated on a case-by-case basis, suggesting the move stops short of a total export ban.
Financial markets reacted sharply to the news. Cadence shares dropped 10.7% and Synopsys shares fell 9.6% before both companies saw partial recoveries in after-hours trading.
The Biden administration has not clarified whether these new controls are part of a broader negotiating strategy amid the pause in escalating tariffs. The White House declined to comment on the developments.
As the global tech rivalry intensifies, the latest U.S. action underscores Washington’s resolve to curb China’s access to technologies critical to military and economic dominance. The long-term implications for U.S. tech firms and Chinese innovation efforts remain to be seen.
