United Nations Security Council Resolution 221, adopted on April 9, 1966, after recalling previous resolutions on the topic (including the provision for an oil embargo), the Council was gravely concerned that Southern Rhodesia might receive a large supply of oil as the Joanna V, an oil tanker, had already arrived at Beira. Resolution 221 was adopted by ten votes to none; the People's Republic of Bulgaria, France, Mali, the Soviet Union and Uruguay abstained from voting.
