This book places international trade law within an economic, political and sociological context, contending that globalisation is characterised by both homogeneity and diversity. The book focuses on the US and the EC, analysing different institutional and substantive aspects of unfair trade instruments, such as anti-dumping and countervailing measures and market access instruments. The book considers political action prescribed by formal constitutions in a wider socio-economic context, rejecting the a-historical and structurally blind normative idea of free trade.
