On March 1, 2011, the Shanghai government started to enforce “Regulations for Comprehensive Management of Shanghai’s Public Security,” which, for the first time, included overseeing commercial and residential buildings and the Internet.
The Regulations subjected the owners of commercial buildings, companies providing affordable housing, and property management to neighborhood Comprehensive Management Committees (an agency at lowest level of China’s national system of social control) and local police authorities. The regulations provided that “public security authorities, state security agencies, and other government organs in economic and information technology, culture, radio, television, and communications shall strengthen their supervision over the Internet, establish and improve the comprehensive prevention and control system for network security, and stop and punish related illegalities and criminal activities.”
