ASEAN countries are promoting regionally balanced development in their policy in response to development disparity resulting from rapid urbanization. This study aims to draw strategic approaches for balanced development based on the current status of territorial development of the ASEAN countries. Through the lens of Korea’s territorial development experience, this study presents three strategic types for balanced territorial development and an analysis framework to connect the strategic types and the territorial conditions of ASEAN countries. This study analyzes the current status from five aspects: (1) the current status of urbanization and industrialization, (2) the size distribution of cities, (3) the spatial structure of the territories, (4) the state of regional development, and (5) balanced development visions and territorial policies. Based on the analysis results, this study categorizes the ASEAN countries that exhibit similar territorial development and applies the strategic types. This study derives policy measures suitable to each strategic type that will help the ASEAN countries to facilitate balanced development in accordance with their territorial state.
