The full text of the revised GPA and the new annexes that list the public procurement covered by all parties to the GPA are available in amp-113. The WTO Public Procurement Agreement is a “multilateral” agreement that means it applies to a number of WTO members, but not all members. The WTO secretariat provides technical assistance to help WTO members from developing countries who wish to learn more about the GPA and/or GPA. If so, and desired by the candidate countries, other intergovernmental organizations (for example. B regional development banks) or governance institutions may also provide technical assistance for GPA membership. The following WTO members are parties to the 1994 agreement: The accession process begins with the submission of an application for membership and includes two main aspects: negotiations between the member and the GPA parties on the GPA hedging offer and verification of the compliance of the member`s contracting rules with the requirements of the MPA, MPA for example, transparency, procedural fairness for suppliers and national audit. The Review Body on Bid Challenges is an organization set up by party states that allows suppliers to challenge irregular government tenders.  These bodies are independent and strive to deal with each case quickly. The review body is also empowered to recommend rapid interim measures, which can be recommended within days, when an evaluation body finds a first-application case for an auction challenge.  In accordance with Revised GPA Article V, specific and differentiated treatment of developing countries can be negotiated in the form of transitional measures such as offsets, tariff preference programmes, higher thresholds initially and the gradual replacement of facilities by a developing candidate country in the accession process, subject to the agreement of other parties and the development needs of the accession member. GPA membership is limited to WTO members who have specifically signed or subsequently joined the GPA. WTO members are not required to join the GPA, but the United States urges all WTO members to participate in this important agreement.
Several countries, including China, Russia and the Kyrgyz Republic, are negotiating GPA membership. International intergovernmental organizations granted observer status to the AMP committee On 30 March 2012, the parties to the GPA adopted a review of the GPA. The revised agreement expands the markets covered by the GPA to provide U.S. products, services and suppliers with new opportunities to participate in centralized and sub-centralized procurement in other GPA parties. The revised agreement also provides for a substantial improvement in the text of the treaty by modernising the text to take into account current procurement practices and to clarify its commitments. The revised agreement came into force on 6 April 2014 following the tabling of the acceptance instrument by ten parties, two thirds of the parties to the agreement on that date.
