During the following months , international efforts mainly concerned the largely unsuccessful United Nations Safe Areas set up in Bosnia and Herzegovina and trying to set up a more lasting ceasefire in Croatia . The two issues virtually merged by July 1995 when a number of the safe areas in eastern Bosnia and Herzegovina were overrun and one in Bihać was threatened .

These developments and the Washington Agreement , a ceasefire signed in the Bosnian theater , led to another meeting of presidents of Croatia and Bosnia and Herzegovina on 22 July , when the Split Agreement was adopted . In it , Bosnia and Herzegovina invited Croatia to provide military and other assistance , particularly in the Bihać area . Croatia accepted , committing itself to an armed intervention
