This dissertation looks at Northeast Asia as a region composed of China, Japan and South Korea in order to understand the regional dimension of international cooperation. It takes the Tripartite Environment Ministers’ Meeting and the China-Japan-Korea Meeting on<p>Information and Telecommunication Standards cases for comparative analysis. Its aim is to<p>examine cooperation and decision-making under uncertainty and to explore how they affect<p>institutional development and enhanced regional cooperation. Analysis of current cooperation activities as well as development of chosen cases illustrates interactions between individuals, organizations and states. Risks associated with decision-making affect<p>behaviors of actors and self-reinforcement mechanisms of institutions creating path<p>dependence. / Doctorat en Sciences politiques et sociales / info:eu-repo/semantics/nonPublished
