Law enforcement in the People's Republic of China consists of an extensivepublic security system and a variety of enforcement procedures. Along with the courts andprocuratorates, the country's judicial and public security agencies include theMinistry of Public Security (MPS) and theMinistry of State Security (MSS), with their descending hierarchy of departments, bureaus (局, "Jú"), subbureaus (副局, "Fù jú"), and stations (所, "Suǒ").
Hong Kong andMacau have separate law enforcement agencies, different legal systems, and are classified as separate jurisdictions under theone country, two systems framework. However, theHong Kong Police Force (HKPF) andPublic Security Police Force often cooperate with the mainland MPS on cases involving cross border crime.
The national security system is made up of theMinistry of Public Security (MPS) and theMinistry of State Security (MSS), thePeople's Armed Police (PAP), thePeople's Liberation Army (PLA), and the state judicial, procuratorial, and penal systems. TheCentral Political and Legal Affairs Commission vets all law enforcement officers and legal officials for political reliability.[1]
TheMinistry of Public Security (MPS) oversees all domestic police activity in China. The ministry is responsible for police operations and detention centers and has dedicated departments for internal political, economic, and communications security. TheMinistry of State Security (MSS) was established in 1983 to ensure "the security of the state through effective measures against enemy agents, spies, and counterrevolutionary activities designed to sabotage or overthrow China's socialist system."[citation needed] TheMinistry of Justice maintains oversees the operation of prisons.[citation needed]
Police cars in the mainland are white with a dark blue swoosh painted on the side such asBYD e6.[11] China does not have a uniform fleet buying program so local departments typically buy from a variety of local dealerships.Volkswagen Santanas andVolkswagen Passats are the most common but other makes and models are present as well.[citation needed]
