The rapidly urbanizing cities in Southeast Asia experience increasing flood impacts due to the consequences of climate change. In these cities, policy efforts to build flood resilience are gaining momentum. The aim of this paper is to understand and assess flood resilience policy development, particularly in cities in developing countries. Bangkok is one of the cities that participates in the 100 Resilient Cities Programme (100RC) - the international policy platform for building resilient cities. In 2017, the Bangkok Metropolitan Administration (BMA) launched the 'Bangkok Resilience Strategy' to translate the resilience concept to its urban context. A framing perspective is adopted to reconstruct the strategy, process and anticipated outcome of Bangkok's flood resilience policy. We studied data obtained from 'insiders' (involved policy makers, experts and consultants) and 'outsiders' (local communities, civil society organizations and news media). Findings indicate that the economic growth frame is prevailing in the development of Bangkok's flood resilience policy, prioritizing structural flood protection with little attention for flood adaptation measures and related social impacts among vulnerable communities. The role of local communities and civil society in the formulation of Bangkok's flood resilience policy is limited. This paper therefore recommends cities in developing countries and cities in the 100RC Programme to organize a more inclusive resilience building process for addressing social problems regarding urban poor communities along with increasing flood safety and protection.
