The Ministry of Public Security is a government ministry of the People's Republic of China responsible for public and political security. It oversees more than 1.9 million of the country's law enforcement officers and as such the vast majority of the People's Police. While the MPS is a nationwide police force, conducting counterintelligence and maintaining the political security of the Chinese Communist Party (CCP) remain its core functions.

The special administrative regions (SAR) of the People's Republic of China are one of four types of province-level divisions of the People's Republic of China directly under the control of its Central People's Government, being integral areas of the country. As a region, they possess the highest degree of autonomy from China's central government. However, despite the relative autonomy that the Central People's Government offers the special administrative regions, the National People's Congress and its Standing Committee remains capable of enforcing laws for the special administrative regions.
