Chinese Lidar Maker Hesai Faces U.S. National Security Scrutiny
Hesai Technology, a Chinese lidar firm with Nvidia connections, was added to the Pentagon's military entity list in 2024 over cybersecurity concerns.
A Chinese manufacturer of lidar sensors has found itself at the center of an escalating U.S.-China technology security dispute. Hesai Technology, which has maintained ties to American chipmaking giant Nvidia, was designated a Chinese military entity by the U.S. Department of Defense in 2024, effectively blacklisting the company as a national security threat.
The Pentagon's designation places Hesai on a list typically reserved for companies the U.S. government believes contribute to China's military-industrial complex. Such listings can severely constrain a firm's ability to conduct business with American partners and suppliers, raising immediate questions about the durability of any existing commercial relationships with U.S. technology companies.

The accusation that Hesai poses a cyber risk to the United States adds a particularly pointed dimension to the case. Lidar technology — which uses laser pulses to map environments in three dimensions — is a cornerstone of autonomous vehicles, robotics, and advanced surveillance systems. Critics of Chinese lidar adoption in American infrastructure have long argued that embedded sensors could serve as data-collection vectors, a concern that the DoD designation now formally amplifies.
The Hesai case reflects a broader pattern in Washington's approach to Chinese technology firms operating in sensitive hardware sectors. Much as scrutiny of Huawei reshaped global telecommunications supply chains, pressure on lidar manufacturers could force American autonomous vehicle developers and other buyers to reconsider their sourcing strategies. The intersection of Nvidia's high-profile AI chip business with a now-blacklisted Chinese sensor maker is likely to draw further congressional and regulatory attention in the months ahead.
