Arbitration Commission of the Peace Conference on Yugoslavia
On 20 November 1991 Lord Carrington asked: "Can the internal boundaries between Croatia and Serbia and between Bosnia and Herzegovina and Serbia be regarded as frontiers in terms of public international law?" Applying the principle of "uti possidetis juris", the commission concluded on 11 January 1992, "The boundaries between Croatia and Serbia, between Bosnia and Herzegovina and Serbia, and possibly other adjacent independent states may not be altered except by agreement freely arrived at... Except where otherwise agreed, the former boundaries become frontiers protected by international law".
Croat–Bosniak War
In February 1994, Boban and HVO hardliners were removed from power while "criminal elements" were dismissed from ARBiH. On 26 February talks began in Washington, D.C. between the Bosnian government leaders and Mate Granić, Croatian Minister of Foreign Affairs to discuss the possibilities of a permanent ceasefire and a confederation of Bosniak and Croat regions. By this time the amount of territory of Bosnia and Herzegovina controlled by the HVO had dropped from 20 percent to 10 percent. Under strong American pressure, a provisional agreement on a Croat-Bosniak Federation was reached in Washington on 1 March. On 18 March, at a ceremony hosted by US President Bill Clinton, Bosnian Prime Minister Haris Silajdžić, Croatian Foreign Minister Mate Granić and President of Herzeg-Bosnia Krešimir Zubak signed the ceasefire agreement. The agreement was also signed by Bosnian President Alija Izetbegović and Croatian President Franjo Tuđman. Under this agreement, the combined territory held by the Croat and Bosnian government forces was divided into ten autonomous cantons. It effectively ended the Croat–Bosniak War. According to Tuđman, Croatian support came only on the condition of American assurance of Croatia's territorial integrity, an international loan for reconstruction, membership into NATO's Partnership for Peace program, and membership into the Council of Europe. According to Western media, Tuđman received intense American pressure, including a threat of sanctions and isolation.
