Under the GPA, a separate article regulates the special and differentiated treatment of developing countries, technical assistance and capacity building. For example, developing countries have the right to maintain specially negotiated clearing regimes in their contracting processes after they join the agreement. The special and differentiated treatment provisions were specified in the text tentatively agreed for a revised agreement and were expanded on some points to make the agreement more attractive and accessible to developing and least developed countries. In accordance with Article V of the revised GPA, specific and differentiated treatment of developing countries can be negotiated in the form of transitional measures such as offsets, tariff preference programmes, higher thresholds and the gradual introduction of enterprises by a developing candidate country in the accession process, subject to the agreement of the other parties and the development needs of the member.

The ministerial statement also stated that the negotiations were limited to transparency aspects and therefore did not restrict countries` flexibility in granting preferences to domestic deliveries and suppliers (9). The accession process begins with the submission of an application for membership and has two main aspects: negotiations between the member member and the parties to the GPA on the offer of coverage of the GPA and the verification of the compliance of the member`s contracting rules with the requirements of the GPA, for example in terms of transparency, procedural fairness for suppliers and national control.
