700 Million Cameras: Inside China’s Foreigner Tracking System

China’s ruling Communist Party has quietly assembled one of the world’s most sophisticated digital drag-nets aimed squarely at foreign visitors. Drawing on an estimated 700 million cameras, facial-recognition software, and mobile data, the Dynamic Control Platform for Overseas Personnel constructs detailed dossiers on non-Chinese nationals. Each file reportedly includes passport details, employer information, and social graphs that reveal who meets whom and where. The platform singles out reporters and citizens from Australia, Canada, New Zealand, the United Kingdom, and the United States for heightened scrutiny at the neighborhood level. Analysts say the system can flag when two monitored individuals appear on the same street camera or share a residential block. The revelations coincide with Beijing’s continued refusal to grant visas to several Western journalists, underscoring the widening gulf between China and the international press corps.
