Arbitrator appointment system mainly involves two issues: qualification and list of arbitrators. The underlying logic of both issues is the same, that is, the law maker does not believe that the parties can reasonably choose arbitrators. The limitation of the right to choose arbitrators is contrary to the current mainstream international commercial arbitration system and does not accord with the demand of current practice. Therefore, the way to improve Chinese arbitrator appointment system is to learn from the mainstream commercial arbitration system and to adopt a more open attitude to arbitration, and to consider the development and characteristics of Chinese own arbitration system. Setting up a negative list of arbitrators’legal qualification and adopting a recommended list of arbitrators are the right way for China to modify the arbitration law.
