Korea has put much effort into providing aid for fragile states in efficient and effective ways. As a part of such efforts, Korea established the Fragile States Assistance Strategy in 2017. However, there is still room for improvement in terms of the effectiveness of Korea’s Official Development Assistance (ODA) implementation under fragile and conflict-affected situations. Accordingly, the study aims to suggest policy suggestions for Korea’s development cooperation in fragile states by comparing and analyzing the current status, policies, and characteristics of aid to fragile states in major donor countries, including Germany, Australia, Denmark, and Japan. In addition, we review Korea’s case and draw following policy implications to tackle the remaining challenges. First, it is requisite for Korea to consolidate the whole-of-government approach and reciprocal coordination mechanisms to support for fragile states for overcoming fundamental causes of fragilites. Second, Korea should choose proper types of aid and sectoral aid allocation suitable for overcoming vulnerabilities and development challenges efficiently and effectively in fragile and conflict-affected states. Lastly, the Korean government should conduct a fragility analysis and manage projects systematically.
