No longer the region of “high north, low tension,” the Arctic, specifically its security landscape, has undergone an immense transformation and is emerging at the forefront of strategic competition. Russia’s invasion of Ukraine imposed an inflection point in Arctic cooperation. As Western cooperation with Russia freezes, Russia is increasingly turning to China for the funding, support, and technology necessary to sustain economic development of the Russian Arctic Zone. Additionally, the accession of Finland and Sweden into the NATO has shifted the Alliance’s geographical center of gravity northward and reinvigorated NATO’s approach to the High North to ensure collective defense along its Northern Flank.
