The ‘Vance-Owen Plan’ may refer to the joint proposals developed by US Secretary of State Cyrus R Vance and British Foreign Secretary David Owen in the late 1970s to secure ‘one man, one vote’ rule in Rhodesia. An alternative ‘Vance-Owen Plan’ would be the peace plans developed by then-UN Special Envoy Vance and EC representative Lord Owen to secure peace between warring factions in Bosnia in the early 1990s.
