Abstract: The implementation of the “Belt and Road” international commercial dispute resolution mechanism and the ratification and entry into force of the “Singapore Mediation Convention” urgently require the establishment of a legislative system for commercial mediation. In weighing the strategic deployment of the Rule of Law and the urgent development needs of the reality, the commercial mediation legislative system should adopt a “three-step” progressive construction plan. Recently, the State Council first formulated the “Interim Regulations on Commercial Mediation” to quickly make up for urgent needs in reality. At the same time, the national legislature followed the principles of scientific legislation to integrate and modify the “People’s Mediation Law”, turning it into a comprehensive “Mediation Law”, and upgrading the provisions of the “Interim Regulations on Commercial Mediation” to Special chapter on commercial mediation. In the future codification of civil procedures, the conventional dispute resolution methods including mediation shall be established as an independent volume in the Code of Civil Procedure, all the provisions of the “Mediation Law” will be integrated into the special chapter of “Mediation”; under this chapter is special section of commercial mediation, including special provisions on commercial mediation.
