The U.S. government said it will tighten rules on selling American technology to China’s police and security forces. Officials found that U.S. companies had sold computer parts and software used to track and watch people in China, including in areas where human rights abuses have been reported. Lawmakers are calling for clear limits and stronger oversight to prevent American tools from being used for surveillance abroad. The new policy aims to keep sensitive technology out of foreign hands and ensure that U.S. products are used for safety, not control.
