During this time, unsuccessful negotiations mediated by the UN were under way between the Croatian and RSK governments. The matters under discussion included opening the Serb-occupied part of the Zagreb–Slavonski Brod motorway near Okučani to transit traffic, as well as the putative status of Serbian-majority areas within Croatia. The motorway initially reopened at the end of 1994, but it was soon closed again due to security issues. Repeated failures to resolve the two disputes would serve as triggers for major Croatian offensives in 1995.
