Bureau of Industry and Security — key-event: Implemented sweeping export controls on AI chips and semiconductor equipment to China

Note: The source directly confirms that the Bureau of Industry and Security implemented export controls on AI chips and semiconductor equipment in October 2022. The claim specifies 'as of 2022-10' (October 2022), which matches the source's statement 'First imposed in October 2022.' The source describes these as sweeping regulations targeting China, which aligns with the claim's characterization. The additional context mentioning 'October 7, 2022 rules' and 'new strategic approach' is consistent with the source's description of these as a departure from prior U.S. trade policy.
