To ease the tensions, the two governments signed an interim treaty, establishing a joint Russo-Ukrainian Black Sea Fleet under bilateral command (and Soviet Navy flag) until a full-scale partition agreement could be reached. Formally, the Fleet's Commander was to be appointed by a joint order of the two countries' Presidents. However, Russia still dominated the Fleet unofficially, and a Russian admiral was appointed as Commander; the majority of the fleet personnel adopted Russian citizenship. Minor tensions between the Fleet and the new Ukrainian Navy (such as electricity cut-offs and sailors' street-fighting) continued.
