This study is mostly based on previous research, which includes Sub-national actor’s attitudes and regional action towards the European Union. The purpose of the study is to investigate if four Swedish municipalities in Värmland operate internationally towards the European Union and deepen an understanding of their actions. The main research question is:   - How can we increase our understanding of municipal action against the European Union?   The research questions of this study are answered through qualitative method and semi-structured interviews were conducted. Eight key informants in position either as politicians or official workers were selected for interviews whose position is either politicians or official workers. The results were then analysed based on theories such as Fusion and regional action. The study shows that the four Swedish municipalities in Sweden operate internationally in varied form. The actions of smaller municipalities seem to be dictated to large extend by the available resources.
