| After the era of reform and opening-up, China formulated reformational principles and polices about banking system, which changed the history of banking in China a lot. Originally China implemented unitary financial supervision, and People's Bank of China is the only supervision organization. As from June 1998 the monetary industry officially implemented separated business operation and supervision. The three major supervision organizations, People's Bank of China, China Securities Regulatory Commission and China Insurances Regulatory Commission, started to be responsible for the supervision of banking, securities and insurance affairs of China respectively. In April 2003, in accordance with the organization reforms of the State Council, China Banking Regulatory Commission was established to take over the supervision from People's Bank of China so as to reach the goal of separating banking supervision from monetary policy.
