The Political Bureau of the Communist Party of China Central Committee, the country's top decision-making body, pledged on Monday to launch a reform of its discipline inspection system.

The move, which came as the CPC announced the outcome of the internal investigation of retired senior military leader Xu Caihou, is an important part of deepening the nation's overall reforms, the top ruling body said in a statement issued after a meeting presided over by Party chief Xi Jinping.

Members of CPC committees at all levels are urged to live up to their responsibility to fight corruption and maintain clean governance.
