Abstract
The Ukraine crisis has led to tensions between Russia and the western states and the Arctic is one of the affected regions. Regional cooperation, institutions, and international law are essential for Arctic governance, and the crisis may thus have wide-ranging consequences for high north politics. The present article develops an interest-based model of Arctic conflict spill-over and examines its strength, based on a case-study of the first 18 months of the Ukraine crisis. Three hypotheses for Arctic conflict spill-over are developed: Arctic conflict spill-over will be less severe than spill-over in other regions, the western states will be more assertive than Russia, and the smaller Arctic states will be less assertive than the larger states. A review of the crisis confirms the bulk of these hypotheses with some exceptions, thus demonstrating that an interests-based model holds some merit, while also showing that a complete understanding of Arctic conflict spill-over necessitates a broader approach. The article concludes that conflict spillover is unlikely, but not impossible, in the Arctic.
