Nvidia pushed back Sunday in response to allegations from Chinese state media that its H20 artificial intelligence chips are a national security risk for China.

A media outlet affiliated with state broadcaster CCTV says the chips cannot be trusted because of ‘back-door’ concerns.

China has reportedly told firms to refrain from using Nvidia's H20 chips after the chipmaker received approval to resume shipments there.

Authorities press companies including ByteDance, TikTok’s parent company, to use domestic suppliers instead.
