Strategic Waterway: The Kerch Straits
Russia now formally controls a much larger portion of the Black Sea, which includes the entire coastline of the Crimean peninsula. The Eastern part of Crimea –including the Kerch straits– are now under Russia’s jurisdiction control. On the Eastern side of the Kerch straits is Russia’s Krasnodar region and extending southwards are the port cities of Novorossiysk and Sochi.
Novorossiysk is also strategic. It is Russia’s largest commercial port on the Black Sea, at the cross-roads of major oil and gas pipelines between the Black Sea and Caspian sea.
