New supervisory commissions will incorporate existing supervisory, corruption prevention and control agencies within the governments and procuratorates, under a decision made by the top legislature on Saturday.

The pilot project of reforming the supervision system, launched in Beijing, and Shanxi and Zhejiang provinces in January, will be expanded nationwide, the Standing Committee of the National People's Congress decided on Saturday at its bimonthly session, which was closed.

Supervisory commissions will be set up across the country by people's congresses at provincial, city and county-levels within their jurisdictions to supervise those exercising public power.
