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".
Croatian War of Independence
A new UN-sponsored ceasefire, the fifteenth one in just six months, was agreed on January 2, 1992, and came into force the next day. This so-called Sarajevo Agreement became a lasting ceasefire. Croatia was officially recognized by the European Community on January 15, 1992. Even though the JNA began to withdraw from Croatia, including Krajina, the RSK clearly retained the upper hand in the occupied territories due to support from Serbia. By that time, the RSK encompassed of territory. The area size did not encompass another of occupied territory near Dubrovnik, as that area was not considered part of the RSK.
