Current membership includes seven LDCs.2 The GSTP recognizes the special needs of the participating LDCs, including, among other things, the need to extend concrete preferential treatment measures and concessions. In the past, only a limited number of offers of nonreciprocal trade concessions were extended to LDCs under the GSTP.3 In 2004, at the eleventh session of UNCTAD (UNCTAD XI) held in Sao Paulo, Brazil, GSTP participants agreed to convene a third round of negotiations to improve preferential tariffs and expand trade ties among signatory developing countries. In addition to the seven LDCs that participate in the GSTP (identified in italics), Burkina Faso, Burundi, Haiti, Madagascar, Mauritania, Rwanda and Uganda have applied for accession to the GSTP.
