Registers like Panama, Mongolia and Tanzania have been busy removing vessels that have visited Crimea, the former region of Ukraine annexed by Russia in 2014, new figures reveal.

Calling the area "temporarily occupied", Vitalii Moshkivskyi, the deputy permanent representative of Ukraine to the IMO, told TradeWinds that since 2017, 11 different flag states have kicked out 50 ships for violating UN and EU sanctions imposed on Russia for the "illegal" annexation.
