This chapter analyses the history of and legislation process of the Chinese police system and police power. After describing the development of Chinese police from 1949, the emergence and improvement of the relevant law have always been important in shaping the policy mechanism of the police. Since 1976, a reform agenda has been implemented. Chinese police officers were given more responsibility to promote new regulations and laws and were given the role of guardian. With the rapid growth of the global economy and technology, China's internal and external security situation has changed considerably, and non-traditional security issues are regarded as a threat to society. Hence, the Police Law of 1995 requires further modification and improvement. In the acknowledgement that continuous legal reform will be necessary in the future, an amendment of the People's Police Law was would be placed on the legislative planning list.
