Bureau of Industry and Security — key-event: Expanded chip export controls, closing loopholes exploited by Nvidia's A800/H800 China-specific chips

NoteThe source directly confirms the claim's key elements: (1) BIS issued expanded chip export controls in October 2023 (matching the 'as of 2023-10' timeframe); (2) the controls specifically addressed Nvidia's A800 and H800 China-specific chips as workarounds/loopholes; (3) the update involved 'updated performance thresholds' (the source states 'The update shifted technical thresholds from interconnect bandwidth to performance density and total processing performance'); (4) the controls expanded equipment restrictions. All core elements of the claim are confirmed by the source text.
