The Biden administration is reportedly considering imposing restrictions on China's access to advanced AI models in an effort to protect U.S. AI technology. The Department of Commerce is exploring regulating the export of proprietary or closed source AI models. This move would complement previous measures aimed at preventing the export of sophisticated AI chips to China. However, the rapidly evolving nature of the AI industry poses a challenge for regulators. The proposed restrictions have been criticized by the Chinese Embassy as "economic coercion." Concerns are raised about the potential misuse of AI models by U.S. adversaries for cyber attacks or the development of biological weapons. The regulatory proposal is still under discussion, highlighting U.S. efforts to address China's AI ambitions.
