Historically, the Kerch strait in Eastern Crimea has played a strategic role.
It constitutes a narrow maritime gateway which links the Black Sea via the Sea of Azov to Russia’s major waterways including the Don and the Volga.
It also ensures maritime transit from the Black Sea to Moscow not to mention the strategic maritime route between the Caspian Sea (via the Volga-Don Canal) to the Black Sea and the Mediterranean.
