In the context of a new globalization, the globalization of Chinese cities and the global communication of global cities in China have become new phenomena in the new era. Globalization and World Cities Study Group and Network (GaWC) at Loughborough University have continually upgraded the rank of Chinese cities in its reports. In the charts of The World According to GaWC 2018, there are 44 Chinese cities among 374 cities listed from ″alpha++″ to ″sufficiency″, accounting for 11.76%, compared with 2012 only 18 cities listed. The pattern is like sports competition, showing that the Chinese national team for urban agglomeration has entered the international arena, and has made a huge progress.  In the meanwhile, it is the thought of building ″a community of shared future for all humankind″ proposed by President Xi Jinping, which is an important part of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, with rich connotation, provides a new approach for urban global communication researches, and shows a new realm in global media studies. Starting from the question of global governance, this study pursues the theoretical concerns and value implications of the thought of building ″a community of shared future for all humankind″, which is a five-in-one thinking providing valuable theoretical enlightenments for the construction of a global media city from the perspective of New Cosmopolitanism. The main value is actually manifested in the city to build an open, inclusive, clean, and beautiful world that enjoys lasting peace, universal security, and common prosperity. To reach this goal, it is necessary to integrate domestic and foreign situations, achieve win-win cooperation through positive-sum game.  From the perspective of media geography, this study also examines the interaction between local and global factors in the following four categories: human interaction, media communication, government governance, and geographic representation in urban space, thus constructing a research model for urban global communication research against the background of new globalization. From the perspective of global communication, these four levels of factors usually have mutual competition, cooperation, mixed coexistence, harmonious symbiosis and future development between their locality and globality. How can Chinese cities better adapt to the tide of global communication and construct a global media city with a global vision and a Chinese style? The essence of this problem is to make the media scale of Chinese cities jump from the local to the global level, or to make the global scale and the Chinese native local scale coexist in a city. Within the urban space of China, many interesting cases or phenomena can be observed and explained by this model. For example, the Syrians in Yiwu, a city with fabulous e-commerce and small commodity market in China, which has no artillery but only business. In this case, it is a contrasting urban media global communication landscape, and it is also an organic tolerance and flexible transformation between locality and globality in a geographical media scale.  Under this model, this study clarifies the era orientation of global communication in Chinese cities, and proposes five strategies: 1) Following the tides of development; 2) Promoting the circulation by breaking through the blockage; 3) Rooting in local community; 4) Forming a local climate by gathering resources; 5) Warming people's heart and making their dreams come true. Through the discussion of urban media and global communication issues, it can be found that its theoretical framework is completed in the perspective of new cosmopolitanism. Finally, this study predicts that there will be more Chinese cities moving to the upper position of the global urban system, realizing the new cosmopolitan and the win-win situation, and realizing the ″world dream″ to build ″a community of shared future for all humankind″.
