Law enforcement in China

Law enforcement in China consists of an extensive public security system and a variety of enforcement procedures used to maintain order in the country. Along with the courts and procuratorates, the country's judicial and public security agencies include the Ministry of Public Security (MPS) and the Ministry of State Security (MSS), with their descending hierarchy of departments, bureaus (, "Jú"), subbureaus (副局, "Fù jú"), and stations (, "Suǒ").

Hong Kong and Macau have separate law enforcement agencies, different legal systems and are classified as separate jurisdictions under the one country two systems framework. However, the Hong Kong Police Force (HKPF) and Public Security Police Force often cooperate with the mainland MPS on cases involving cross border crime.
