US tech firm Nvidia said in a statement to China Daily on Friday that cybersecurity is critically important to it and Nvidia does not have “backdoors” in its chips that would give anyone a remote way to access or control them.

China's cyberspace regulator on Thursday summoned Nvidia over security risks concerning its H20 AI chip sold to China.

The company was asked to give explanations and submit relevant supporting materials on this issue. This is aimed at safeguarding cyberspace and data security for Chinese users per laws on network and data security and personal information protection, according to the Cyberspace Administration of China (CAC).

Recently, Nvidia's artificial intelligence chips have been alleged to pose serious security risks, and some US lawmakers have called for advanced chips exported abroad to be equipped with "tracking and positioning" functions.
