Recent years have seen increased academic attention in urban studies on the flows of city artefacts and images. Conceptualised as ‘immutable mobiles’, the Macao Pavilion and its associated objects on show at Shanghai Expo 2010 are examined for the ways they encouraged and regulated uniformed flows of people and city images. Specifically, these immutable mobiles projected Macao’s lofty dreams of paradoxical affinity to and difference from mainland China—the city is a steadfast Special Administrative Region of China, but the immigration flow of Chinese citizens has been tightly regulated. This paper unpacks the ways in which urban actants articulate and perform such contradictory imaginings of the (im)mobilities of this postcolonial territory. Accordingly, it provides a basis for further study of post-colonial conditions in Macao, and adds to post-colonial research on mobilities in and of Chinese urban spaces.
