How do trade agreements interact with agreements on human rights or the environment? In case of conflict, which agreement should prevail? Must trade disputes be examined only from he angle of trade rules or should account be taken also of non-trade values? Pauwelyn considers these questions here, providing a framework for how the different rules of international law interact, and procedural guidelines in the event of conflict between them. This book will interest trade diplomats, international civil servants, lawyers, NGOs and scholars of public international law and international trade law.
