On 4 March 1970, Constant Schuurmans, Belgian Ambassador to Bonn, forwards to Karl Schiller, German Minister for the Economy, the decisions that Baron Snoy et d’Oppuers, in his capacity as President-in-Office of the Council of Ministers of the European Communities, would like to submit to the Council of Finance Ministers. These include a proposal for the establishment of an ad hoc group, chaired by Pierre Werner and tasked with devising a plan by stages for the creation of an economic and monetary union.
