The Agreement on Government Procurement (GPA) requires that open, fair and transparent conditions of competition in public procurement be guaranteed. To this end, the text of the agreement sets out general principles and detailed procedural requirements that the parties to the GPA are required to apply in covered procurement activities. The GPA is a plurilateral agreement within the WTO, which means that not all WTO members are parties to the agreement. Currently, the agreement has 20 parties and 48 WTO members. 36 WTO members/observers participate as observers in the GPA Committee. Of these, 12 members are contributing to the agreement. Recognizing that the integrity and predictability of public procurement systems are essential for the efficient and effective management of public resources, the proper functioning of the economies of the Parties and the functioning of the multilateral trading system, recognizing the importance of using electronic means for the procurement facilities covered by this Agreement and promoting their use, The fundamental objective of the GPA is to open up public procurement between its parties. Following several rounds of negotiations, the GPA parties have opened procurement activities worth an estimated $1.7 trillion each year to international competition (i.e., to suppliers of GPA parties offering goods, services or construction services). Recognizing the need for an effective multilateral framework for government procurement in order to achieve greater liberalization and expansion of international trade and to improve the framework for conducting international trade, in order to ensure an open, fair and transparent playing field in government procurement, several WTO Members have adopted the Agreement on Government Procurement (GPA). Recognizing that measures in the field of government procurement should not be prepared, adopted or applied in such a way as to protect domestic suppliers, goods or services or to discriminate against foreign suppliers, goods or services; The procuring entity shall provide suppliers with tender documents containing all the information necessary for suppliers to prepare and submit responsive tenders. Unless already stated in the notice of intended procurement, those documents must contain a full description arising from a covered contract in which the supplier has or has had an interest. .
