An Associated Press investigation reveals that major U.S. tech companies, including IBM, Dell, NVIDIA, and Oracle, played a foundational role in building China’s vast digital surveillance state. For over two decades, these firms sold billions of dollars in hardware and software, including ‘predictive policing’ systems, directly to Chinese police and government entities. This technology enabled the creation of a ‘digital cage’ to monitor and control citizens, quash dissent, and facilitate the mass detention and persecution of ethnic minorities, particularly Uyghurs in the Xinjiang region. Despite repeated warnings, American firms marketed their products as tools for ‘stability maintenance.’ While sanctions have slowed the direct flood of technology, the infrastructure they established remains, and U.S. tech continues to support China’s surveillance apparatus through various channels, raising profound human rights and security concerns.
