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".
Bosnia and Herzegovina–Serbia relations
The beginnings of formal cooperation can be traced to the Bosnian War; Republika Srpska got support from Serbia. At the Dayton Agreement, the President of the Republic of Serbia Slobodan Milošević represented the Bosnian Serb interests due to absence of Radovan Karadžić. Dayton Agreement ensure the right for entities in Bosnia and Herzegovina to establish special parallel relationships with neighboring countries consistent with sovereignty and territorial integrity of Bosnia and Herzegovina. Agreement on Special Parallel Relations is signed in February 28, 1997. The Agreement was implemented December 15, 2010. Until now was organized significant number of formal and informal meetings between representatives of two sides.
