A museum is a non-profit public organization with a mix of functions，including cultural heritage collection，academic research，public service，and foreign exchange. As global，cultural，and people-to-people exchanges grow，museums play an increasingly important role in cultural diplomacy and mutual learning between civilizations. By taking museums as a medium for international communication in the new era，this report examines developments in international communication for ten representative，prestigious museums in China. Then，based on the museum utility theory and the new situation of international communication in the new era，the report constructs a conceptual model for international communication capacity building of prestigious Chinese museums with five capacity indicators：collection curation，academic exchange，cultural services，mass communication，and interpersonal communication. Based on the said analysis，this paper provides a glimpse into the evolutionary path of international communication practices for prestigious Chinese museums：first，leveraging the regional differences and local knowledge of museums across China to piece together the unique landscape and rich identity of the Chinese culture；second，integrating exhibition curation，smart services，and social promotion functions to build “comprehensive digital museums” for cultural dialogues beyond time and space；third，incorporating Chinese expertise in the narrative vision of global history by establishing an academic dialogue and discourse system with international influence；fourth，transitioning from media to cultural discourse by promoting the innovative restructuring of the international power of discourse and harmonizing media-led mass communication with audience-engaged interpersonal communication.
