Four major international peace plans were proposed before and during the Bosnian War by European Community (EC) and United Nations (UN) diplomats before the conflict was settled by the Dayton Agreement in 1995.
On 11 March 1992, the Assembly of the Serb People of Republika Srpska (the self-proclaimed parliament of the Bosnian Serbs) unanimously rejected the original peace plan,[citation needed] putting forth their own map which claimed almost two thirds of Bosnia's territory, with a series of ethnically split cities and isolated enclaves and leaving the Croats and Bosniaks with a disjointed strip of land in the centre of the republic.
However, he put forth a revised draft of the original which stated that the three constituent units would be "based on national principles and taking into account economic, geographic, and other criteria.
[3] On 28 March 1992, after a meeting with US ambassador to Yugoslavia Warren Zimmermann in Sarajevo, Izetbegović withdrew his signature and declared his opposition to any division of Bosnia.
[4][5] In early January 1993, the UN Special Envoy Cyrus Vance and EC representative Lord Owen began negotiating a peace proposal with the leaders of Bosnia's warring factions.
The proposal, which became known as the "Vance-Owen peace plan", involved the division of Bosnia into ten semi-autonomous regions and received the backing of the UN.
The Vance–Owen plan was a roughly sketched map, it did not establish the definitive outline of the 10 cantons and depended on final negotiations between the three ethnic groups taking place.
[4] Between February and October 1994, the Contact Group (U.S., Russia, France, Britain, and Germany) made steady progress towards a negotiated settlement of the conflict in Bosnia-Herzegovina.
