The author offers a survey of recent studies on the role of the European Union in world affairs. While some theoretical and conceptual progress has been made since the 1970s and 1980s, a good deal of the current work is still largely descriptive. Only a small number of studies take factors such as culture, norms, or ideas sufficiently into account. Referring to such variables, however, promises a value added for the explanation of certain phenomena in EU external relations. With reference to IR Theory, an institutionalist approach that conceptualises ideas as an intervening variable is therefore proposed.
