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".
Accession of Serbia to the European Union
On 7 November 2007, Serbia initiated a Stabilisation and Association Agreement (SAA) with the European Union. This was a milestone in Serbia's accession negotiations and was executed following the advice of chief war crimes prosecutor Carla Del Ponte, who advised the EU that the country was complying with the tribunal but stipulated that Ratko Mladić must be in The Hague prior to any official signing. Mladić was subsequently arrested on 26 May 2011 and was extradited to the International Criminal Tribunal for the former Yugoslavia to stand trial. On 20 July 2011, Goran Hadžić became the last indicted fugitive to be arrested. After setbacks in the political field, on 7 December 2009 the EU unfroze the trade agreement with Serbia and the Schengen countries dropped the visa requirement for Serbian citizens on 19 December 2009.
