While Korea strengthens its strategic approach for regional economic cooperation to expand its partnership with emerging countries and its Official Development Assistance (ODA) volume is highly concentrated in Asia region, Korea still focuses on cooperation with each country based on priority countries’ Country Partnership Strategy (CPS) without any integrated regional cooperation strategy. Strengthening inclusive partnerships would be a key to reduce the development gap in the region, by supporting regional programs such as the ASEAN Connectivity and Mekong Subregion development projects. To improve policy coherence and tackle the region-wide problems, Korea should adopt an integrated regional cooperation approach by reflecting the characteristics of Asia. This study analyzes changes in the socio-economic conditions and development environment in the Asia region and provides policy implications for preparing regional cooperation strategy for Asia.
