This paper reviews and re-assesses the contemporary state of research on Cham cultural heritage sites, which are associated with the pre-modern Champa civilization in Vietnam. For this purpose, architectural heritage, sculptures, and museums related to the potential of common interests are taken into consideration across the intersection of the local Cham community, the Vietnamese government, and international scholars. There are some conflicts between these interested parties, which have resulted from unequal dynamics, which occasionally result in lasting tensions and errors in judgement. Our research findings result in an actionable plan with systematic solutions, which we outline in this paper. We argue the proposed plan will improve the management, conservation, and promote Cham cultural heritage sites more sustainably.
