Europeanization literature has found that, in general, subnational authorities prefer to target the EU indirectly via member state channels. This article tests whether these findings hold in the non-legislative domain of the European Semester. With respect to the Belgian case, the article concludes that all Belgian subnational authorities indeed primarily use the cooperative intra-state channels as a response to the domestic division of competences and the EU decision-making procedures. It also finds that in addition especially Flanders invests substantially in extra-state strategies towards EU institutions. The article concludes that stronger time constraints, lower compliance pressure and the more politically salient issues of the European Semester trigger the most prosperous and identity prone region to adopt additional extra-state channels on top of the dominant intra-state channels.
