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".
Bosnian War
The Croat-Bosniak war ended with the signing of a ceasefire agreement between the HVO Chief of Staff, general Ante Roso, and the ARBiH Chief of Staff, general Rasim Delić, on 23 February 1994 in Zagreb. The agreement went into effect on 25 February. A peace agreement known as the Washington Agreement, mediated by the US, was concluded on 2 March by representatives of the Republic of Bosnia and Herzegovina, Croatia and Herzeg-Bosnia. The agreement was signed on 18 March 1994 in Washington. Under this agreement, the combined territory held by the HVO and the ARBiH was divided into autonomous cantons within the Federation of Bosnia and Herzegovina. Tuđman and Izetbegović also signed a preliminary agreement on a confederation between Croatia and the Federation of Bosnia and Herzegovina. The Croat-Bosniak alliance was renewed, although the issues dividing them were not resolved.
