Recurring pro-Kremlin narrative about Ukraine violating Russian territorial integrity in the Sea of Azov. The use of the Kerch strait and the Sea of Azov is regulated by a bilateral treaty between Russia and Ukraine, signed in 2003 and ratified by Russia in 2004. According to the document, the Sea of Azov is considered to be the “internal waters” of both Russia and Ukraine.
