In China, most civil disputes are resolved simply and promptly through alternative dispute resolution methods such as reconciliation between the parties and people's mediation. However, there are a small number of cases in which civil disputes cannot be resolved properly and escalate to the point of "acts violating public security administration". At that time, if the public security organ determines that mediation is possible for the incident, it may initiate "public security mediation". The purpose of this paper is to clarify the background, history, current situation, and achievements of China's public security mediation, and to show how administrative ADR and public security mediation systems should be improved in the future.
