In 1995 mini Contact Group of foreign ambassadors in Zagreb drafted a comprehensive proposal to Croatian PresidentFranjo Tuđman and the leaders of the Republic of Serbian Krajina in Knin aimed at peaceful resolution of the Croatian War of Independence. The proposal was known as the Z-4 Plan and it proposed reintegration of Krajina to Croatian constitutional framework on the basis of a new Constitutional Agreement which defined Krajina as an autonomous region of Croatia. The plan did not envisage special autonomy for Eastern Slavonia but rather two years long transitional period. Krajina leaders in Knin refused to receive the draft proposal which subsequently led to Operation Flash and Operation Storm and complete military defeat of Krajina resulting in over 200,000 Croatian Serb refugees who left their homes. Rump and geographically separated territory of Eastern Slavonia, Baranja and Western Syrmia remained the only part of Croatia under Serb control. Contrary to Krajina, Eastern Slavonia shared a long border with the Republic of Serbia. It was also economically and socially dependent and politically much more closely aligned with authorities in Belgrade and Novi Sad than Krajina. This led international community to belief that Croatian intervention in Eastern Slavonia will trigger Yugoslav military reaction and will lead to the larger escalation of hostilities. At the same time military defeat of Krajina and signing of the Washington Agreement opened the space to resolve the armed conflict in Bosnia which US Administration wanted to use before the 1996 United States presidential election. Croatia conditioned its participation at the Dayton Peace Conference on the resolution of conflict in Eastern Slavonia, while international community insisted on avoidance of any new major escalation of Yugoslav crisis. This created conditions in which peaceful resolution was preferred or acceptable to all parties concerned.
United NationsTransitional Administration was requested to ensure the possibility for the return of refugees and displaced persons to their homes of origin. The same rights were to be enjoyed both to those who have left the region or those who have come to the region from other parts of Croatia.
Joint Implementation Committees formed both by local Croat and Serb communities assisted the UNTAES in governing the region. Local police forces were organized to have equal number of ethnic Croats and Ethnic Serbs plus additional smaller number from all the other communities in the region.
Minority rights provisions
The agreement itself and subsequent developments and commitments during the UNTAES mandate represent the basis on which numerous minority institutions operate today. Establishment of the Joint Council of Municipalities, with a Serbian majority population was one of explicit rights granted to the Serb community. Other institutions such as Serb National Council and weekly magazine Novosti were established at the same time, while some, such as Radio Borovo, were registered in accordance with Croatian laws. Agreement requires respect of the highest levels of internationally recognized human rights and fundamental freedoms.
International impact
Erdut Agreement was quoted as an precedent and comparable case by the Ukrainian diplomats for implementation of Minsk II package of measures agreed within the framework of Minsk Protocol aimed at halting the War in Donbass.
