<P> Held between September 1 and September 14, 1981, in Paris, the first UN LDC Conference was organized to finalize the UN's "Substantial New Programme of Action" for the 1980s in Least Developed Countries . This program, which was unanimously adopted by the conference attendees, argued for internal reforms in LDCs (meant to encourage economic growth) to be complemented by strong international measures . However, despite the major economic and policy reforms initiated many of these LDCs, in addition to strong international aid, the economic situation of these countries worsened as a whole in the 1980s . This prompted the organization of a 2nd UN LDC conference almost a decade later . </P> <P> 2nd UN LDC Conference </P> <P> Held between September 3 and September 14, 1990, once again in Paris, the second UN LDC Conference was convened to measure the progress made by the LDCs towards fulfilling their development goals during the 1980s .

These new principles were embodied in the "Paris Declaration and Programme of Action for the Least Developed Countries for the 1990s". </P> <P> 4th UN LDC Conference </P>
