Counselor, Deputy Permanent Representative of Ukraine to the International Maritime Organization (IMO) Vitalii Moshkivskyi earlier said that Ukraine had expressed its protest at the IMO over the unauthorized expansion by the Novorossiysk NAVTEX station of its service area into the Sea of Azov and the Kerch Strait.

"Only the Berdiansk NAVTEX station of Ukraine has full responsibility for broadcasting MSI [Maritime Safety Information] into this service area. Called on the IMO to consider the unauthorized unilateral actions of the Russian Federation, which threaten the safety of navigation," he wrote on Facebook on January 17.
