China's anti-graft system will see a fundamental change as the top legislature is scheduled to review a draft amendment to the Constitution and the country's first law on supervision to give legal footing to a new national supervisory commission.

Some 2,980 deputies attending the first plenary session of the 13th National People's Congress, starting on Monday, will deliberate on the two draft measures, according to the agenda.

Only a plenary meeting of the NPC can adopt amendments to the Constitution and laws related to the country's fundamental systems.

A major change proposed to the Constitution is to list the supervisory commissions as a new type of State organ.

The proposal says supervisory organs will be listed together with administrative, judicial and procuratorial organs of the State, all of which are created by the people's congresses, to which they are responsible and by which they are supervised.

The supervisory commissions will independently exercise their power of oversight and not be subject to interference by any administrative organ, public organization or individual, the proposal says.

The draft supervision law, reviewed by the NPC Standing Committee twice, in June and December, details how the supervisory commissions work, as well as their duties and obligations.

The law applies to all public officers, including civil servants and those working for public schools and medical institutes, which means that the nation's fight against corruption covers every public corner, experts said.

To better study how to operate the system, pilot supervisory commissions were set up in Beijing and in Shanxi and Zhejiang provinces in 2016. In October, the test was extended across the country.

By Sunday, the nation's 31 provinces, municipalities and autonomous regions had elected directors of their supervisory commissions.

The commission at each level integrates forces to fight corruption in government authorities, including anti-graft bureaus in people's procuratorates, and then works together with local disciplinary authorities of the Communist Party of China.

Such joint efforts have brought more public officers under supervision. For instance, about 2 million public officers are now under supervision in Henan province, up from 908,000
