From partners to allies: Finland and Norway in a new era

Finland’s decision to apply for NATO membership in 2022 altered Nordic security and defence dynamics. It also reset Finland’s relations with its neighbouring states – including longstanding NATO member Norway. In this policy brief, we discuss the evolving relationship between Finland and Norway. Despite their history as peaceful neighbours, divergent security arrangements generated political distance between Finland and Norway during the Cold War. After the end of the Cold War, their security policies gradually became more aligned, as evident also in heightened Nordic security cooperation, Finnish and Swedish participation in NATO exercises, and, more recently, the signing of a series of defence agreements with each other as well as with Sweden and the United States. Following Finland’s NATO accession, both states have anticipated a deepening of the Finnish-Norwegian alliance. We identify some areas where Finland and Norway may benefit from collaborating and exchanging perspectives in the coming years. This includes in the management of shared institutional frameworks, security concerns in the Arctic and Baltic Sea regions, the future relationship with the United States, and a more antagonistic Russia.
