For the 22 years since the establishment of the CICA mechanism，certain progress has been achieved in the two aspects of idea innovation and mechanism construction. However，as there are a large number of CICA member states，there exist apparent differences among them in terms of economic development，political system，social culture，willingness of participation，and expectation. With the restriction and disturbance of the internal and external factors，there might be a centrifugal tendency from the CICA mechanism among the member states. In addition，the function and positioning of the CICA is not explicitly clarified；its operation efficiency and effectiveness should be improved；and there has the leadership deficiency from the big powers in the construction of the CICA mechanism. The above factors have posed challenges to and become the bottleneck of the development of the CICA mechanism. The successful holding of the fourth CICA Leaders’ Summit in Shanghai 2014 marked the new historical stage for the development of the CICA. As the initiating state of the “Asian Security Concept” and the new Chair state of the CICA mechanism，China will play an irreplaceable role in the promotion of the development of the CICA mechanism.The Conference on Interaction and Confidence-Building Measures in Asia（CICA）was proposed by Kazakh President，Nursultan Nazarbayev，on the 47th UN General Assembly in 1992. Since then，the scale of the CICA has been growing continuously. There are currently 26 member states，and 11 observers（countries and organizations）. CICA has become “one of few important cross-civilization and cross-region platform for the discussion of regional security and cooperation issues in Asia”CICA：the Important Platform of Dialogue，Trust，and Interaction in Asia，speech at Lanting Forum by Mr. Chen Guoping，Deputy Minister，Foreign Affairs Ministry of China.
