AbstractThe European Union's role in international trade contains two signifi cant con tra dictions: fi rst, although its trade policy, with some notable exceptions, is generally fair ly liberal, it has been the respondent in a number of high-profi le trade disputes; second, al though a champion of multilateralism, the EU has had problems com ply ing with World Trade Organization (WTO) judgments. I argue that these contradictions in the EU's trading persona are due to the internal dy nam ics of European policy-mak ing, which create 'regulatory peaks' where the member governments' rules diverge, and render the resulting rules dif fi cult to alter.
