The Governments of Denmark and Germany pointed out the provisions of the Bonn/Copenhagen Declarations of 1955, which were analysed above. In the view of the Governments, German unification did not change the status in international law of the Bonn/Copenhagen Declarations. For its part, the Government of the Federal Republic of Germany has said that the Bonn Declaration constituted a binding international obligation, which has been approved by the German Bundestag and can be amended or terminated only with the agreement of the Government of Denmark.

There are general references to concerns of economic and social rights. Examples are the provision (Article 2.2) that minorities should have the right to participate in economic life, and the somewhat vague provision (Article 4.3) that ’States should consider appropriate measures so that persons belonging to minorities may participate fully in the economic progress and development in their country’. It has been argued that certain provisions of the Declaration can be construed as recognizing basic subsistence rights, in that depriving a group of the basic economic resources necessary to sustain its existence would violate the principles of the Declaration.
