China's civil servant law, newly revised in December 2018, took effect Saturday.

The revised law clarifies systems of civil servant promotion and assessment, and includes statutes to improve rewards and benefits such as pension schemes.

It also tightens supervision over civil servants, keeping its statutes in line with the supervision law and disciplinary rules of the Communist Party of China.

The revised law bans civil servants from working as leaders of industry regulators or administrative departments in charge of supervising businesses run by their spouses, children or in-laws.

The civil servant law first took effect in 2006.
