China aims to establish a system to punish corrupt officials by the end of 2017, the Political Bureau of the Communist Party of China Central Committee said.

Supervision of how officials exercise power will be enhanced, and a punishment system, under which officials dare not take bribes, will be formed, according to a five-year work plan that the Political Bureau approved on Tuesday.

The work plan - made by the Central Commission for Discipline Inspection of the CPC, the country's top anti-graft agency - is the commission's second five-year plan targeting corruption.
