Background | Nauru's phosphate deposits began to be mined early in the 20th century by a German-British consortium; the island was occupied by Australian forces in World War I. Nauru achieved independence in 1968 and joined the UN in 1999. Nauru is the world's smallest independent republic. | Ancient Peru was the seat of several prominent Andean civilizations, most notably that of the Incas whose empire was captured by the Spanish conquistadores in 1533. Peruvian independence was declared in 1821, and remaining Spanish forces defeated in 1824. After a dozen years of military rule, Peru returned to democratic leadership in 1980, but experienced economic problems and the growth of a violent insurgency. President Alberto FUJIMORI's election in 1990 ushered in a decade that saw a dramatic turnaround in the economy and significant progress in curtailing guerrilla activity. Nevertheless, the president's increasing reliance on authoritarian measures and an economic slump in the late 1990s generated mounting dissatisfaction with his regime. FUJIMORI won reelection to a third term in the spring of 2000, but international pressure and corruption scandals led to his ouster by Congress in November of that year. A caretaker government oversaw new elections in the spring of 2001, which ushered in Alejandro TOLEDO as the new head of government. |

Economy - overview | Revenues of this tiny island have come from exports of phosphates, but reserves are expected to be exhausted within a few years. Phosphate production has declined since 1989, as demand has fallen in traditional markets and as the marginal cost of extracting the remaining phosphate increases, making it less internationally competitive. While phosphates have given Nauruans one of the highest per capita incomes in the Third World, few other resources exist with most necessities being imported, including fresh water from Australia. The rehabilitation of mined land and the replacement of income from phosphates are serious long-term problems. In anticipation of the exhaustion of Nauru's phosphate deposits, substantial amounts of phosphate income have been invested in trust funds to help cushion the transition and provide for Nauru's economic future. The government has been borrowing heavily from the trusts to finance fiscal deficits. To cut costs the government has called for a freeze on wages, a reduction of over-staffed public service departments, privatization of numerous government agencies, and closure of some overseas consulates. In recent years Nauru has encouraged the registration of offshore banks and corporations. Tens of billions of dollars have been channeled through their accounts. Few comprehensive statistics on the Nauru economy exist, with estimates of Nauru's per capita GDP varying widely. | Thanks to foreign investment and the cooperation between the government and the IMF and World Bank, growth was strong in 1994-97 and inflation was brought under control. In 1998, El Nino's impact on agriculture, the financial crisis in Asia, and instability in Brazilian markets undercut growth. The following year was again lean year for Peru, with the aftermath of El Nino and the Asian financial crisis working its way through the economy. Political instability resulting from the presidential election and FUJIMORI's subsequent departure from office limited growth in 2000. The downturn in the global economy further curtailed growth in 2001. President TOLEDO, who assumed the presidency in July 2001, has been working to reinvigorate the economy and reduce unemployment. Economic growth in 2002 is estimated at 4.8%, led by construction in the retail and gas sectors. |
