This paper is an attempt to reassess the role of failure in policy mobilities. Empirically, this paper examines the various aftermaths of, and the continuing trans-local connections originating from, the prominent but un-materialized Sino-British Shanghai-Dongtan eco-city—with a particular consideration on its relation with a subsequently realized project—the Sino-Singapore Tianjin eco-city. The findings reveal that despite its apparent failure, Dongtan eco-city established a set of urban planning procedures adopted by many, including those who designed and delivered the Tianjin eco-city. Meanwhile, Dongtan’s failure to materialize motivated the Chinese government to pursue collaboration with the Singaporean government over the increased involvement of private Western partners. The intent to avoid association with Dongtan’s failure also fostered a new eco-urbanism model based on rebranding the planning practices of Singapore’s public housing. Parts of Dongtan eco-city have also lived on through the international circulation of a piece of planning software that was first developed for the failed project. This paper contributes to the policy mobilities literature by challenging its dominant focus on successful exemplars and exploring how a project fails in implementation yet parts of it remain mobile, influential and present in other developments. This paper also advances the understanding of contemporary urban sustainability by revealing how eco-urbanism models are co-produced in this globalizing era between the global North and South, as well as within the global South.
