The improvement of Qianhai international commercial dispute resolution mechanism is not only the requirement of national strategy，but also the demand of practical development. In order to build an international commercial dispute resolution center，Qianhai has reformed the international commercial case trial mechanism，built an international commercial arbitration highland，and explored a new commercial mediation mechanism in line with international standards. Qianhai is facing challenges in the construction of international commercial dispute resolution mechanism. It is necessary for Qianhai to continue to give full play to the legislative advantages of the legislative power of the Special Administrative Region，standardize the supporting measures of commercial mediation，build an efficient cohesion mechanism，and build itself into the preferred place for international commercial dispute resolution.
