The meeting dedicated to the initiative that stemmed from the need to regulate the navigation regime on the section of the Kupa River, which forms the border between the Republic of Slovenia and the Republic of Croatia was held on August 28, 2018 on the premises of the Chamber of Commerce of Dolenjska and Bela Krajina in Novo Mesto. 

The main topic of the meeting was related to the initial proposal of the Sava Commission's Decision on the Vessel Traffic Regime on the joint sector of the Kupa as an example of a possible solution to the issue of the harmonization of the navigation regime and the documentation designed within the framework of the project "Common Approach to the Regulation of the Navigation Regime on the Kupa River".
