In our country, it is an important duty of the peoples police to mediate certain types of disputes, which belongs to the “adjudication power” in the new police power. The theoretical basis of policeoriented mediation is the peoples character of police power, the expansion of police power and the polices credibility. The main types of policeoriented mediation are public security mediation and traffic police mediation. While exerting the irreplaceable function of preventing and dissolving social contradictions, the policeoriented mediation is confronted with different dilemma. Appropriate measures, such as stimulating the vitality of various kinds of administrative mediation and formulating a systematic and clear policy, should be taken so as to improve the policeoriented mediation.
