A social media account linked to China’s state broadcaster CCTV has claimed that Nvidia’s H20 chips are unsafe for the Chinese market.
The article, posted by Yuyuan Tantian on WeChat, said the chips could have “backdoor” functions, allowing actions such as remote shutdown.
The post also said the chips are not technologically advanced or environmentally friendly. “When a type of chip is neither environmentally friendly, nor advanced, nor safe, as consumers, we certainly have the option not to buy it,” the article concluded.
The H20 chips were designed for China after U.S. export restrictions on advanced AI chips in 2023. In April 2025, the Trump administration banned their sale to China but reversed the decision in July.
On July 31, China’s cyberspace watchdog summoned Nvidia to a meeting to address possible backdoor risks. Nvidia later said its products do not contain any such security flaws.
The latest criticism follows a recent commentary by state newspaper People’s Daily, which urged Nvidia to provide “convincing security proofs” to regain trust from Chinese users.
Nvidia has not responded to the new comments.
