The decision notes that, having considered threats to national security in the south and the east of Ukraine, in the waters of the Black and Azov Seas and the Kerch Strait, caused by Russian aggression, the NSDC confirmed the presence of conditions that could lead to critical destabilization of the economic, social and political situation, sea blockade of the coast of Ukraine.
