In the globalization 3.0 era ushered in by new media，“all to all” communications have unleashed tremendous social power and innovative sources. In the context of China’s active participation in global governance and the ensuing new round of development of economic globalization，China has appeared the world’s spotlight and put up “friend circle” and partnership networks around the world. In the meantime，political parties，governments，political figures and public service agencies in the world have in recent years registered on the world’s largest Chinese social media，Weibo，the only “Network China” for them to directly connect with all social strata in the Chinese society，converge the ecology of different professional clusters，and interact with multiple public opinions and strengthen exchanges，dialogue and cooperation between China and Chinese in the rest of the world. Weibo has become a more direct and more effective means of communications in international public relations and political communications and a practical need for foreign governments to get an insight into Chinese public sentiment，interact with Chinese popular will and get to know China’s development. Over the nearly nine years in the development of foreign administrative Weibo in China，foreign agencies have been blended with Chinese netizens in cultural interaction，with consensus and conflict，opportunities and challenges coexisting. Either way，Weibo has allowed the tradition-based “head-of-state diplomacy” to transit and upgrade to personalized “public socializing of governments.”
