A group of US lawmakers issued a warning Thursday over allowing tech giant Nvidia to sell advanced chips in China, alleging that its support to AI startup DeepSeek has helped boost Chinese military capabilities. "When Nvidia technology ends up powering China's military, that's not innovation; it's a security failure," the Select Committee on China said in an X post. "Nvidia's products were used by DeepSeek and ended up supporting an AI model used by the PLA," it said, referring to China's People's Liberation Army. Last year, a low-cost generative AI model from China's DeepSeek, on par with US rivals, upended assumptions of American dominance in the fast-moving field. But DeepSeek routes Americans' data to the Chinese government "through infrastructure tied to a US-designated Chinese military company," it said.
