China has heightened security and surveillance in Beijing ahead of the 75th anniversary of the People's Republic, according to RFA. Authorities are restricting entry to the city and closely monitoring rights activists. Lawyer Li Wenzu was detained temporarily, and others, like journalist Gao Yu, have had communication blocked. These measures are part of China's "stability maintenance" efforts, aimed at preventing unrest during politically significant events. Some activists have been barred from Beijing or are under heavy surveillance, with reduced funds limiting the use of supervised detentions outside the city.
