Haiti continues to suffer the consequences of the 1991 coup. The irresponsible economic and financial policies of "de facto" authorities greatly accelerated Haiti's economic decline. Following the coup, the United States adopted mandatory sanctions, and the OAS instituted voluntary sanctions aimed at restoring constitutional government. International sanctions culminated in the May 1994 United Nations embargo of all goods entering Haiti except humanitarian supplies, such as food and medicine. The assembly sector, heavily dependent on U.S. markets for its products, employed nearly 80,000 workers in the mid-1980s. During the embargo, employment fell from 33,000 workers in 1991 to 400 in October 1995. Private, domestic and foreign investment has been slow to return to Haiti. Since the return of constitutional rule, assembly sector employment has gradually recovered with over 20,000 now employed, but further growth has been stalled by investor concerns over safety and supply reliability.
