Background

Crimea is a peninsula on the northern coast of the Black Sea, connected to mainland Ukraine by a narrow isthmus. Russia annexed it in March 2014 following a disputed referendum held under military occupation, an act recognised by fewer than a dozen UN member states. Ukraine, the EU, and the United States consider the annexation illegal under international law.

The peninsula hosts Russia's Black Sea Fleet headquarters at Sevastopol, making it the cornerstone of Russian naval power projection into the Mediterranean. Since 2022, Ukrainian long-range strikes have repeatedly targeted the fleet and Crimean military infrastructure, sinking or damaging multiple warships and forcing Russia to relocate vessels to Novorossiysk. The Kerch Bridge connecting Crimea to mainland Russia was struck twice, in October 2022 and July 2023.

Crimea's status is a central obstacle in any peace negotiations. Russia considers the annexation non-negotiable; Ukraine insists on full territorial restoration. Western sanctions explicitly cite the annexation, and any normalisation of Crimea's status would require lifting sanctions regimes maintained by over 40 countries.
