Since Russia’s invasion of Ukraine in February 2022, the Arctic region has been the focus of many economic sanctions by Western countries, particularly the European Union. The consequences for the Russian economy are immediate, with the suspension of several hydrocarbon plant development projects, Arctic LNG2 in particular. The withdrawal of European companies from the project and the interruption of the supply of technologies essential to its operation could affect the Kremlin’s ambitions in its strategy for the development of the Arctic region. The same is true for the construction of the LNG ice-breaking tanker fleet, which was supposed to be in phase with the commissioning of Arctic LNG2. However, Vladimir Putin remains adamant on his Arctic policy and is pushing Russian industrialists to find and implement solutions to compensate for the defection of Western technologies. Russia’s absence from the Arctic Council, its escalation of security issues in the northern space, and the Kremlin’s desire to make the Northern Sea Route even more secure, all point to a resurgence of tension in this region, which until now has enjoyed an exceptional level of cooperation.
