Croatia's accession to the EU will change the rules for regional cooperation beyond the Central European Free Trade Agreement (CEFTA). While some treaties involving EU competence will need to change or lapse, the underlying economic rationales for cooperation will remain. Regional cooperation was developed as part of the Stabilization and Association Process and brings political and economic benefits by increasing market size and addressing similar policy challenges. Going forward, "soft" cooperation initiatives can continue alongside strategies encompassing the Western Balkans. Businesses remain committed to cooperation while governments and businesses will need to better define new opportunities for small and medium enterprises.
