The establishment of ISO/TC249 in 2009 have opened a new door for TCM international standardization. To learn about the current situation, locate problems of the development ISO/TC249 and support the decision-making, this paper tries to set up an evaluation index system for participation level of China in ISO TCM international standardization actives. The system includes four aspects: the participation level of TCM management, the level of experts’ registration, participation level of standards developing and the participation level of ISO member bodies in ISO/TC249. The results show that: 1) China had greatly engaged in the management of TCM; 2) It had a quantity advantage in registered experts, but still needs enlarge experts’ distribution and optimize expert’s structure in WG; 3) In terms of standards developing, China’s advantage was not as significant as participation level of management and the quality of experts; 4) Further contribution should be made to the level of ISO member bodies participated in ISO/TC249.
