The tracing of historical origins and disciplinary trajectories enables us to reveal that international communication, as a specific manifestation of global information flow and media evolution, is primarily influenced by the interplay of three societal factors: the roots of political conflicts, the catalytic role of economic and technological developments, and the reshaping of values into distinct blocs. These factors intertwine with the awareness of external exploration across different historical periods. Traditional knowledge production in international communication has evolved along two main lines: political economy and cultural studies. These paths have given rise to three major paradigms—propaganda, global communication, and intercultural communication—each stemming from differing core units of analysis. Together, they have constructed a multifaceted interpretive framework for understanding self-identity and the relationship between self and the external world in the information age since the beginning of the 20th century. This paper argues that on the new journey in the new era, efforts should be made to weaken the attributes of hierarchical control and power conflict derived from the practices of Western industrial societies and the Cold War. In the context of an era marked by the fusion of “new subjects, new networks, new media, and new values,” there is a need to return to the original purpose of communication: the sharing of information and the collective responsibility it entails. This will enable the construction of a new paradigm driven by Chinese modernization for the exchange and mutual learning of civilizations. Such a paradigm aims to unify humanity around shared values, foster the building of a human community with a shared future, and create new forms of human advancement.
