The Adriatic Ionian Euroregion (AIE) is an international association established on the 30th of June 2006 in Pula (Croatia) for the promotion of trans-national and inter-regional cooperation between regions and local authorities of the Adriatic and Ionian basin. The association counts 33 members (Regional and Local authorities from Italy, Croatia, Greece, Bosnia and Herzegovina, Montenegro and Albania). All members are units of territorial self-governments and most of them are NUTS2 (the first level below State, in conformity with the European Community nomenclature NUTS, and with the administrative organization of each country). The total extension of the involved territories is about 200.000 square kilometers with an estimated population of around 20 Millions of inhabitants. The AIE represents a model for cross-border and interregional co-operation aimed to promote the coordinated and integrated development between regions of the area. Since 2006, the AIE has been targeting its efforts towards ensuring the interests of its members and towards the common development of the whole area. Furthermore the association supports the members, especially those in the European accession process, to create joint initiatives and to prepare the regional stakeholders to be qualified in the implementation of the cohesion policy and to deal with the European financial instruments.
