"The INTERREG initiative must include eligible areas with special emphasis on border areas, islands and both mountain and non-mountain areas, such as the prefecture of Arta in Greece, whose omission from Annex I of the Commission' s communication is ill-considered."
Il est impératif que l'initiative Interreg inclue des régions éligibles tout en privilégiant en particulier les régions frontalières, insulaires, montagneuses et non montagneuses, comme le département Arta en Grèce, qui, à tort, est exclu de l' Annexe I de la communication de la Commission.
