Partition Treaty on the Status and Conditions of the Black Sea Fleet
The Partition Treaty on the Status and Conditions of the Black Sea Fleet consists of three bilateral agreements between Russia and Ukraine signed on 28 May 1997 whereby the two countries established two independent national fleets, divided armaments and bases between them, and set forth conditions for basing of the Russian Black Sea Fleet in Crimea. The treaty was supplemented by provisions in the Russian–Ukrainian Friendship Treaty, which was signed three days later.
