Nvidia has denied the existence of “backdoors” in its chips amidst China’s scrutiny over security concerns, particularly regarding its H20 AI processing units. The US tech giant confirmed it would resume H20 sales to China following the easing of export restrictions by Washington. However, China’s Cyberspace Administration has summoned Nvidia to address potential security vulnerabilities. This situation reflects broader US-China trade tensions, with China promoting its domestic 910C chip as an alternative, potentially undermining reliance on foreign technology. Ultimately, Nvidia’s commitment to serving China complicates the geopolitical landscape, especially as trade headwinds and economic challenges persist.
