The arbitration rule of CIETAC was vastly revised and was put in force on May 1, 2005. By its revision, China has improved its arbitration system. Chinese arbitration law had many problems when it was enacted in 1995, but the problems could not be avoided because of the poor surroundings for arbitration in China. As China has not had much experience in operating its legal system effectively, and also has little in the way of studies on legal theory that would allow it to deal with its laws in a flexible manner, authorities usually wait to revise a law until enough relevant experience has been accumulated. Therefore, during the 10 years since its enactment, China has resolved the problems within its arbitration law through revision of arbitration rule rather than by revision of the law itself. As this law is a basic one in ruling the arbitration system in China, there are some limitations as to how far the system can be developed through revision of arbitration rule alone. In spite of the limitations, the revision in 2005 contributed a great deal to resolving the existing problems within Chinese arbitration law. The biggest problem in the arbitration law is the Chinese arbitration law that restricts party autonomy. With the revision of the arbitration rule, many problems concerning party autonomy were circumvented. This occurred because the arbitration rule now provides parties the opportunity to choose arbitration rule other than the CIETAC arbitration rule, and even allows parties to agree to amend articles in the CIETAC arbitration rule -- a very important revision indeed. In addition to party autonomy, there are other improvements for example, there is an enhancement of the independent character of the CIETAC, clearing of jurisdiction, easing in the formation of arbitration agreement, improvement in the way arbitrators are chosen, and enhancement in the cultural neutrality of the arbiter. Problems still remain that can only be solved by revision of the arbitration law itself. These problems relate to the governing law of the arbitration agreement, the collection of evidence, custody of property, selection of chief arbiter, interlocutory awards, etc. In addition, some non-legal problems must also be resolved, like the actual judicial review of arbitration awards or difficulties of executing arbitration awards.
