Council Decision 94/800/EC ( 8 ) approved in particular the World Trade Organisation Agreement on Government Procurement (the ‘GPA’). The aim of the GPA is to establish a multilateral framework of balanced rights and obligations relating to public contracts with a view to achieving the liberalisation and expansion of world trade. For contracts covered by Annexes 1, 2, 4 and 5 and the General Notes to the European Union’s Appendix I to the GPA, as well as by other relevant international agreements by which the Union is bound, contracting authorities should fulfil the obligations under those agreements by applying this Directive to economic operators of third countries that are signatories to the agreements.
