Global Norm Diffusion in East Asia: How China and Japan Implement the Responsibility to Protect

This article addresses the problem of global norm diffusion in international relations with particular reference to the implementation of 'the responsibility to protect' (R2P) in East Asia. Exposing the limits of previous work on norm localization, we develop the framework of the norm diffusion loop. Rather than understanding norm diffusion as a linear top-down process, we demonstrate that the reception of R2P has evolved in a far more dynamic way that can best be described as a feedback loop. We first look into the processes and causal mechanisms that helped to construct R2P as an emerging transnational soft norm; then we analyse the challenges of diffusing R2P from the global to the regional and domestic levels; and, finally, we examine the variation of norm effects within the same region across states, investigating in particular how R2P has shaped Chinese and Japanese policy responses respectively.
