With states from Africa and Asia joining the United Nations, development issues became increasingly important, resulting in the expansion of the United Nations in the development area, including the establishment of the United Nations Development Programme (UNDP) in 1965 and negotiations on an International Economic Order (NIEO) as part of the North-South conflict in the 1970s. The 1980s were characterized by financial crisis and the retreat of the United States, which triggered a reform of the budgetary process and the downsizing of the Organization. With the end of the Cold War, the rediscovery of and renaissance of the United Nations were hailed; the first half of the 1990s saw a major expansion of the Organization and the reform associated with the Agenda for Peace launched by Secretary-General Boutros Boutros-Ghali.
