STRING is the political cross-border partnership between Hamburg and Schleswig- Holstein in Germany, the Capital Region of Denmark and Region Zealand in Denmark, and Region Skåne in Sweden. The STRING partnership was founded in 1999 as an INTEREG A programme with the focus on establishing a new fixed link between Denmark and Germany. In 2008, Germany and Denmark signed a State Treaty, agreeing on the establishment of the fixed Fehmarn Belt link. In the light of this, the cooperation between the STRING Partners changed towards promoting regional development and green growth in the corridor stretching from the Öresund Region to Hamburg. In 2011 the partners agreed on establishing a permanent STRING secretariat to coordinate and promote the joint agenda of the partners, and implement the political decisions.
