Assembly of the UN, in 1977, received a resolution from the 117th WFUNA Executive Committee meeting, which requested: "The Security Council of the UN to give urgent consideration to the taking of immediate steps to ensure that no State, multinational or other body or person be allowed to provide South Africa or Rhodesia with any equipment, technology or production of nuclear weapons of any kind". WFUNA facilitated high-level informal consultations on disarmament issues between key experts of the US and USSR during the Cold War. It organized a number of NGO Seminars on disarmament in cooperation with the UN, UNESCO and other NGOs. During its history, WFUNA has served as a forum for global dialogues on development. Several suggestions, like the establishment of an Economic Commission for Africa, were first adopted at the WFUNA Plenary Assemblies and then endorsed by governments. WFUNA has actively supported reform of the UN and its capacity to meet new tasks and challenges. WFUNA has continually received recognition from the highest ranks of the UN. The sentiments in this statement by UN Secretary-General, Dag Hammerskjöld, to WFUNA's 12th Plenary Assembly were shared by his successors: "I wish... to express my appreciation of your most essential service. At the same time, I wish to urge you to fresh endeavors. Over the years you have accomplished much and have acted with an ever increasing sense of your great responsibilities." For many years WFUNA conducted a fund raising program based on the sale of first day covers of UN stamps and lithographs produced by artists and celebrities, such as Picasso, Lou Zheng Jang, Miró, Salvador Dalí, Ruben Leyva, Al Hirschfeld and Andy Warhol to promote the ideals of the UN. This highly successful program ran for several decades during the 20th century. The UN General Assembly has adopted several resolutions expressing appreciation for WFUNA's efforts to support the values of the UN. In 1986 resolution 41/68 recognizes WFUNA as "the only non-profit that is entirely dedicated to mobilize popular support for the goals and principles of the United Nations" and asks for "all governments to help WFUNA" in its actions. In 2013, resolution 64/86 commends the World Federation of United Nations Associations and its United Nations associations for the valuable contributions they have made, and calls for continued collaboration between the World Federation and the Department of Public Information in support of their complementary objectives".
