evidence: Moreover, in view of the Crimea annexation, Russia now proceeds from the fact that the Sea of Azov is no longer just an inland sea of Ukraine and Russia, but actually a Russian sea. After all, one of the positions on how the borders of Ukraine and Russia in the Azov Sea could be determined was to see them as a continuation of land borderlines. Accordingly, before the annexation of Crimea, Russia's share in the Azov Sea was rather small, which apparently was not what the Kremlin sought. Now, of course, Russia believes that if Crimea is Russian, and, according to the approach mentioned, much of the Azov Sea is now Russian. [...] It is also necessary to consider the possibility of denouncing the agreement with Russia on the use of the Sea of Azov, which says that this is an inland sea, and proceeding from the fact that it is an international sea, we need to start unilaterally applying international maritime law there. Then it will clearly define both our territorial waters and our economic zone and will in fact enable us to ban Russia from setting up such provocations as, for example, the closure of Ukrainian territorial waters of the Sea of Azov for live fire drills of their navy or the illegal detention of Ukrainian ships, or obstruction of Ukraine's implementation of lawful navigation.
