Chinese prosecutors will improve supervision of criminal investigations by the police authorities to ensure better due course of the law and human rights.

Procurator-General Cao Jianming told chief prosecutors at a national meeting on Saturday that the Criminal Procedure Law should be properly implemented and all procuratorial agencies should improve the supervision of the recording, investigation, trial and law enforcement of criminal cases.

Prosecutors were also told to play a greater role in the supervision of death penalty reviews.

China will begin to pilot a program whereby prosecutors are stationed at police stations downtown, the city outskirts and areas with high incidences of crimes, the meeting was told.

Implementation of supervisory system reform measures were stressed to fight corruption.

As procuratorial agencies in relevant pilot regions should properly carry out the reform measures, those in other regions were urged to ensure no weakening in the countercorruption campaign and no change in the "zero tolerance" stance against corruption.
