Most days, Marc Hofer, a cybersecurity researcher and journalist based in Amsterdam, trawls the internet for clues about how China surveils its citizens, a subject that has fascinated him since he worked there as a foreign correspondent. Mr. Hofer, 46, was doing his usual scan earlier this year when he came across something called “Dynamic Control Platform for Overseas Personnel.” It was a futuristic dashboard — like something from the movie “Minority Report” — that appeared to track foreigners in the northern Chinese city of Zhangjiakou, a popular skiing spot that co-hosted the 2022 Winter Olympics. The system’s dashboard said it tracked more than 700 foreign residents living in the city. In total, it had entries for nearly 12,000 people, which included fugitives, people from Hong Kong and Taiwan, as well as more than 300 foreign journalists. Some of them had not been to Zhangjiakou.
