Whakaotihia te rerenga e whai ake nei: Ko Eastern Slavonia, Baranja, me Western Syrmia i hangaia mai i te waahanga anake o te Republic of Serbian Krajina (RSK) i whakaekehia e nga ope kawanatanga o Croatia i Akuhata 1995. Whai muri i te Operation Storm i Akuhata 1995, i whakahokia ai te nuinga o te Republic of Serbian Krajina ki te mana o Croatia, ko Eastern Slavonia, Baranja me Western Syrmia i noho hei rohe "de facto" motuhake. I muri tonu i te otinga o
Operation Storm, i kii te Perehitini o Amerika a Bill Clinton, i roto i te anga o te kaupapa ki te whakamutu i te pakanga i Bosnia, me " "... he mahere mo te wa roa mo te otinga pumau ki te ahuatanga i Eastern Slavonia... i runga i te mana o Croatia me nga kaupapa i whakaahuatia i te mahere Z-4". I roto i tenei wa i ruarua a Croatia i waenga i te otinga taapori, hoia ranei, engari na te kaha o te akiaki a te hapori o te ao, i whakakahoretia te ahei o te urutau hoia. I te Whiringa-a-rangi 1995, i hainatia e nga kaiarahi Serb o te rohe te Whakaaetanga Erdut, i whakaaetia ai te whakauru ano o tenei rohe ki Croatia. I tutuki te whakaaetanga Erdut hei wāhanga o ngā whiriwhiringa i te huihuinga o te Whakaaetanga Dayton. Heoi, mai i te 2007, kaore i whakaaetia e te roopu whakawhitiwhiti korero a Croatia te mahere Z-4 i whakaarohia e te Perehitini Bill Clinton hei turanga mo nga whakawhitiwhitinga korero.
