In this article we compare US and EU support for bilateral and
multilateral international trade law. We assess the support for international
law of both trading blocs by focusing on the following four dimensions:
leadership, consent, compliance and internalization. Although we find strong
support for international trade law from both the US and the EU in general, we
also witness some variation, most notably in relation to the design of
preferential trade agreements (PTAs) and compliance with World Trade
Organization (WTO) law. Turning to explaining these (moderate) differences, we
argue that outcomes in US trade policy can best be explained by a domestic
political factor, namely the direct influence of interest groups. Although the
involvement of societal interests also goes a long way in explaining EU
behavior, it does not tell the entire story. We posit that, in EU trade policy,
institutions are a particular conditioning factor that needs to be stressed.
Moreover, we suggest that foreign policy considerations in managing trade
relations have characterized EU’s support for international trade
law.
