New York Times: “China monitors its 1.4 billion people on an unparalleled scale, with the help of cameras, cellphone signals and national IDs. The database Mr. Hofer found offered a rare window into how extensively the Chinese authorities also surveil foreigners, displaying entries about people categorized by nationality, with their birth date, sex, marital status, address and occupation, and sometimes their religion.”

“It also included instances when they were captured on camera at traffic intersections, markets, shopping malls or other locations, including a mosque.”
