Driven by global economic and cultural competition, Asian megacities seek future-oriented local and global self-representation using cutting-edge museums of contemporary art. This article analyzes the embedding of two vanguard museum projects, the “Museum+” in Hong Kong, China, and the new Museum of Modern and Contemporary Art in Seoul, South Korea, into long-term urban planning strategies and concepts. In order to understand the intended purpose and process of how the new museums of contemporary art are devised as public spaces of cultural selfrepresentation and urban identity building, the study monitors the complete design process from the city government’s urban and institutional planning strategies over architectural design to the museum’s mission statement and collection strategy. By comparatively tracing the museum projects in Hong Kong and Seoul, the evidence shows that, although they share a common global cities agenda, their pathways of urban place-making and community-building vary greatly. These variations depend on the historical role and current geopolitical repositioning of each city.
