Strengthening democratic participation in community governance and improving the socialization，legalization，intelligence，and professionalization of community governance are the important directions for the construction of social governance proposed by the Party’s Nineteenth Congress，and are also an important part of China’s political development. The international community is the most challenging and forward-looking special section in current community governance field. It focuses on the core issue of how to rationally distribute governance power between government，social，and professional organizations. Diversified international community building practices have important pilot values and features. Through strengthening democratic participation in community governance，and building a co-construction responsibility mechanism for the community，the grass-roots party organizations and residents’ committees will be better focused on political functions，and at the same time，the risk sharing and co-governance mechanism between the government and social professionals will be widely established. China’s experience in building an international community is instructive for the broader meaning of China’s national governance system and the optimization of the Party’s political power.
