The idea of “a Community of a Shared Future for Mankind” in the new era is not only based on the common values of mankind, but also has rich and multi-dimensional connotations. Such dimensions include those from traditional Chinese culture, scientifc socialism, cross-cultural community, ecological community, and imaginary community. Exploring the significance and connotations of the thought of “a Community of a Shared Future for Mankind” from these five different perspectives helps deepen our appreciation of this thought. Furthermore, communicating the idea of “Building a Community of a Shared Future for Mankind” in the global contexts should be explored first and foremost from the perspectives of interracial/interethnic, intracultural, cross-cultural, comparative-cultural, intercultural, multicultural, transcultural and global communication and their subsequent transformations all in one. The form and content of “representation, transmission and transculturation” of this thought in different countries and cultures will inevitably both collide and merge with the language, society, and culture of a given country or culture, thus accruing a plurality of interpretations in addition to the mainstream political discourse. Especially, it may experience a continuous contingency in its integration into other national cultures and undergo a process of both deterritorialization and re-territorialization of the ideological terrain in different spatial-temporal contexts, which would be a trajectory for it to enhance global relevance and accelerate the trend of its universalization.
