In the wake of reform in Vietnam and the end of the cold war, overseas Vietnamese are returning to their former homeland in increasing numbers. For most of the first generation in the diaspora, memories of wartime Saigon are now being augmented by a touristic experience of contemporary Saigon/Ho Chi Minh City. This essay asks how the co-presence of these differently spatialized and temporalized ways of knowing the city affects the production and consumption of images of Saigon in overseas Vietnamese communities in the West. Based on media ethnography carried out in Vietnamese households in Sydney, the paper argues that changes in the way Saigon is represented in overseas Vietnamese popular culture reflect a shift in the larger politics of diasporic identity. While narratives of exile and refugeehood remain potent forms of affective (if not instrumental) politics in overseas Vietnamese contexts, transnational forms of consciousness and identification are beginning to enter into diasporic public culture, albeit in a highly contested way.
