The Divergent Aid Ideas in North-East Asia:Comparing Japan and South Korea’s Asymmetric ODA toward ASEAN

Abstract

This study critically analyzes the Official Development Assistance (ODA) policies of Japan and the Republic of Korea (ROK) toward ASEAN (2010–2023). Challenging assumptions of aid homogeneity, the paper argues that the increasingly asymmetric ODA patterns are deeply rooted in their distinct, historically constructed ‘aid ideas’. A quantitative and ideational- institutional framework is used to map these policy divergences. While quantitative data (OECD DAC, QuODA) confirm ROK's superior alignment with international norms versus Japan's loan-centric economic infrastructure priority, the core of the divergence is ideational. Japan’s ODA ideology is founded on ‘self-help’ and explicitly seeks ‘national interest’ (2003 Charter), justifying its consistent deviation from DAC norms in favor of commercial and geopolitical returns. This shift was a political response to internal and external pressures post-Cold War. Conversely, ROK’s aid ideology is profoundly shaped by its unique history as the world’s first major recipient country to transition into a DAC donor. This narrative fuels a powerful domestic and international drive for institutional legitimation as an ‘advanced donor,’ resulting in the prioritization of universal international norms, as codified in the 2010 ‘Framework Act on International Development Cooperation.’ ROK's policy path is thus characterized by normative compliance, contrasting sharply with Japan's strategic mercantilism. The study concludes that Japan and ROK represent two distinct models, providing crucial policy implications. ASEAN can strategically navigate the complementary yet asymmetric nature of the aid—leveraging Japan for economic infrastructure and ROK for social development—to maximize its development outcomes.
