However, as the Agreement will now be concluded by the Council on behalf of the European Community and by the Commission on behalf of the European Coal and Steel Community only, certain corrections of errors in the text of the Agreement are necessary. These are set out in detail in the Annex to this letter, which forms an integral part of this letter.As
