Ukrainian ports have lost $400 million in potential revenue from Russia’s seizure of Crimea and its chokehold on a key shipping passage with a bridge that connects the peninsula to mainland Russia, The Financial Times reported.

President Vladimir Putin inaugurated the $4 billion bridge on May 15, 2018, with a ceremonial truck ride across its 18-kilometer span. The United States and Europe, which recognize Crimea as legally Ukrainian territory, had condemned the Russian bridge for impeding the navigation of ships into Ukraine from the Sea of Azov.
