Trump Administration Plans Ban on New Chinese Data Center Devices
WASHINGTON — August 4, 2026
The Trump administration is preparing a proposal that would block imports of new Chinese-made data center components into the United States as part of a broader effort to strengthen the security of infrastructure supporting artificial intelligence (AI).
The proposed measure focuses on new models of Chinese optical transceivers, devices that transfer data through fiber-optic cables inside data centers. Officials involved in the discussions hope to publish the rule before the end of the year, although the proposal could still be changed or withdrawn before it is finalized.
The planned restriction is intended to reduce security risks linked to critical digital infrastructure. U.S. officials are concerned that foreign-made networking equipment could be used to collect sensitive data, install malicious software, or disrupt services that support AI systems and cloud computing.
If approved, the rule would become another step in Washington's wider strategy to reduce dependence on Chinese technology in sectors considered important to national security. Policymakers have increasingly focused on securing supply chains before foreign technology becomes deeply integrated into U.S. infrastructure.
The proposal is expected to affect Chinese manufacturer Zhongji Innolight, one of the world's largest suppliers of optical transceivers. The company was added to a U.S. defense-related list earlier this year that identifies firms alleged to have links to China's military. The company has not publicly responded to the proposed restriction.
The announcement also influenced financial markets. Shares of several U.S. optical networking companies, including Coherent, Lumentum, and Applied Optoelectronics, rose after reports of the proposed ban, as investors anticipated increased demand for domestic suppliers.
China criticized the reported plans, urging the United States to stop targeting Chinese companies. Officials at the Chinese embassy in Washington said Beijing would take necessary measures if its interests were significantly harmed.
Industry experts note that replacing Chinese suppliers may not be straightforward. Chinese manufacturers currently hold a significant share of the global transceiver market, while U.S. competitors may need time to expand production capacity. As a result, major cloud service providers could face higher equipment costs during any transition.
The proposal follows earlier U.S. restrictions on Chinese products including telecommunications equipment, drones, routers, robots, and power inverters. Regulators have argued that these measures are intended to reduce potential national security risks associated with critical infrastructure.
The administration has previously taken action against Chinese technology companies over concerns involving intellectual property protection and cybersecurity. Although trade tensions between Washington and Beijing eased in some areas over the past year, technology and national security remain major areas of disagreement.
The proposed restriction has not yet been finalized, and authorities have not confirmed the final scope or implementation timeline.
