OpenAI backs US bill to curb China's AI chip access

OpenAI has confirmed support for bipartisan congressional legislation to block China's access to AI chips and chipmaking equipment, adding momentum to measures gaining traction after the scandal that ousted Jensen Huang as Nvidia's CEO. The package includes three proposals targeting high-end chip sales, preventing diversion of Nvidia processors, and restricting China's access to ASML machinery, with plans to attach them to must-pass defense legislation. Nvidia's allies have mobilized against the provisions, but Huang's departure has weakened the company's opposition. Lawmakers, including top congressional leaders, have voiced support for the measures, which face potential veto threats from President Trump and risks of aggravating China's rare earth export controls. The bills could still be scrapped amid ongoing negotiations.
