BEIJING, Aug 10 (Reuters) - Nvidia's ( NVDA ) H20 chips

pose security concerns for China, a social media account

affiliated with China's state media said on Sunday, after

Beijing raised concerns over backdoor access in those chips.

The H20 chips are also not technologically advanced or

environmentally friendly, the account, Yuyuan Tantian, which is

affiliated with state broadcaster CCTV, said in an article

published on WeChat.

"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.

Nvidia ( NVDA ) did not immediately respond to a request for

comment.

H20 artificial intelligence chips were developed by Nvidia ( NVDA ) for

the Chinese market after the U.S. imposed export restrictions on

advanced AI chips in late 2023. The administration of U.S.

President Donald Trump banned their sales in April amid

escalating trade tensions with China, but reversed the ban in

July.

China's cyberspace watchdog said on July 31 that it had summoned

Nvidia ( NVDA ) to a meeting, asking the U.S. chipmaker to explain

whether its H20 chips had any backdoor security risks - a hidden

method of bypassing normal authentication or security controls.

Nvidia ( NVDA ) later said its products had no "backdoors" that would

allow remote access or control.

In its article, Yuyuan Tantian said Nvidia ( NVDA ) chips could

achieve functions including "remote shutdown" through a hardware

"backdoor."

Yuyuan Tantian's comment followed criticism against Nvidia ( NVDA )

by People's Daily, another Chinese state media outlet.

In a commentary earlier this month, People's Daily said Nvidia ( NVDA )

must produce "convincing security proofs" to eliminate Chinese

users' worries over security risks in its chips and regain

market trust.
