Territorial cooperation is assumed to bring added value to regional and local activities, contribute to balanced development across European regions, and increase integration between different parts of the European territory. Territorial cooperation can bring added value in terms of finding solutions to common problems, help to mobilise critical mass, contribute to learning, and build structures for future territorial cooperation. Cooperation across national borders has a long tradition in the Nordic Region. Cross-border cooperation committees (CBCCs) were established in various border areas as early as the 1960s. When the Interreg initiative was introduced in the Nordic Region in 1995 it brought additional funding and strengthened cross-border and transnational cooperation. The scope of this study is to explore the added value of Interreg programmes to the Nordic CBCCs. The priority areas of the cross-border programmes covering Nordic regions will be compared with the objectives of Nordic cross-border cooperation. Further, two examples will be highlighted to illustrate the two-way linkage between Interreg cross-border programmes and Nordic CBCCs.
