The Collected Documents of The Group of 77 at the United Nations provides a chronological record of events and documents of the Group of 77 since its creation in 1963. This Fifth Volume assembles a selection of materials pertaining to the Perez-Guerrero Trust Fund for South-South Cooperation (PGTF) which was established by the United Nations General Assembly at the initiative of the Group of 77 in 1983 to provide financial support for projects in various fields of South-South cooperation. It is named after Dr. Manuel Perez-Guerrero (1911-1985) of Venezuela, who was Secretary-General of UNCTAD (1969-1974), and Chair of the Group of 77 in New York during 1980-1981. He promoted the development agenda (particularly South-South cooperation) on a global scale, which became a central feature of the development core mission of the United Nations system.
