Amid a fierce competition with China for AI dominance, the United States is grappling with critical vulnerabilities in its data center infrastructure due to heavy dependence on Chinese-made power equipment, raising national security concerns and supply chain risks.
- About 30-40% of key data center power hardware imports come from China.
- US President declared a national emergency over foreign threats to bulk-power equipment.
- Chinese firms dominate global optical transceiver component supply for data centers.
What happened
The United States is increasingly scrutinizing its reliance on Chinese power equipment in the data center sector as the country races to build AI infrastructure. Chinese companies supply a significant share of essential components such as transformers, switchgear, batteries, and optical technology crucial for powering and maintaining data center operations. These parts are pivotal for converting and managing electricity within the centers, ensuring uptime for AI workloads.
In response, US leadership has taken formal action. A recent executive order declared a national emergency concerning foreign threats posed by imports of bulk-power system equipment. This authorizes stricter controls and conditions on transactions involving these critical components. The move reflects growing concerns about the strategic risks in depending heavily on Chinese hardware amid ongoing US-China tensions over AI technology leadership.
Why it matters
Data centers are the backbone of AI development and advanced computing, requiring highly reliable and secure power infrastructure. The reliance on Chinese suppliers for key power components—including devices that control voltage, circuit safety, and backup power—exposes US AI infrastructure to risks of supply disruption or malicious interference. This vulnerability could affect national security and the broader technology ecosystem.
Additionally, China’s dominant position in supplying optical transceiver units used in data centers highlights another critical dependency in data transmission technology. As the US pushes forward with large-scale AI buildouts, any interruptions or increased costs due to supply chain constraints could impact deployment speed and operational reliability, posing significant challenges to maintaining leadership in AI innovation.
What to watch next
Washington’s implementation of the executive order and subsequent measures targeting Chinese imports of power equipment will be key indicators of how aggressively the US moves to reduce these dependencies. Observers should also track efforts by American companies and allies to develop domestic or alternative supply chains for transformers, switchgear, batteries, and optical components to mitigate risks.
China’s reaction and strategic adjustments to maintain its supply dominance will also be important. The geopolitical battle between the US and China over AI and critical technology supply chains is evolving rapidly, with implications for global tech cooperation, trade security, and national defense. Monitoring policy developments and trade restrictions related to bulk-power infrastructure in the coming months will provide crucial insight into the future landscape of AI infrastructure security.
