China's Surveillance System Found Tracking Foreigners Including Utility Bills

A cybersecurity researcher has made a chance discovery revealing that China's surveillance apparatus extends significantly to foreign nationals within its borders. The system, which already monitors China's 1.4 billion citizens through cameras, phone signals, and national identity records, appears to track foreigners down to granular personal data such as gas bills. The finding highlights the broad scope of Beijing's digital monitoring infrastructure beyond its own citizenry. The discovery raises fresh concerns about the privacy and security of foreign residents and visitors in China.
