EXPOs are one of the places for the negotiation of the concepts “Danish contribution to the Expo ” an, “co-branding” as a “Public-Private Partnership” (nation branding, organizational branding, corporate branding).This paper looks at the social / discursive construction of the mentioned concept/s (macro) by analyzing the retrospective evaluation (micro) of the event itself and the co-operation by different stakeholders. This relation between the conceptual level and the everyday enactment and (indirect) negotiation might be seen as a dichotomy; but the different levels might only be different places for negation of meaning, enactment and institutionalization of the concepts.
