Global Forum for Associations of Regions (FOGAR)
From the FOGAR web site:
Because Regions are closer to their citizens, their voice should be heard at all levels of decision-making. This is the role of Regions United / FOGAR: bringing together Regions around the world and being their ambassador within international organisations promoting a global policy of balanced development and territorial cohesion.
Thus, Regions United / FOGAR is the unique representative body of Regions seeking their recognition as major players of global governance.
