China's central leadership held a meeting on Friday, calling for more standardized law enforcement practices. President Xi Jinping presided over the meeting. According to a statement released after the meeting, in order to ensure that police power is used properly, the management of law enforcement should be "systematic" and procedures should be documented or recorded.

The statement also said authorities should strive to let the public feel social justice in every single law enforcement act and every single case. The call comes amid a series of cases that have occurred nationwide which involve allegations of abuse of police power.

The recent case of 29-year-old Lei Yang who died in police custody after a vice raid two weeks ago in Beijing, has prompted questions by the public about whether the police used excessive force. Prosecutors in Beijing are investigating the case to see if there was any police misconduct involved. So far, no conclusion has been reached.
