“Muntschick’s contribution is a valuable addition to the literature on (external) influences on regional organisations, and to ongoing debates among scholars and policymakers about theory building and empirical/case studies. He provides a substantial theoretical framework with which to analyse the role of external and internal actors on the crucial policy field of regional organisations, and offers insights into a still under-researched region.” (Mariel Reiss, South African Journal of International Affairs, October 31, 2018)
