Background | Discovered and claimed by Portugal in the late 15th century, the islands' sugar-based economy gave way to coffee and cocoa in the 19th century - all grown with plantation slave labor, a form of which lingered into the 20th century. While independence was achieved in 1975, democratic reforms were not instituted until the late 1980s. Although the first free elections were held in 1991, the political environment has been one of continued instability with frequent changes in leadership and coup attempts in 1995 and 2003. The recent discovery of oil in the Gulf of Guinea promises to have a significant impact on the country's economy. | Britain conquered Burma over a period of 62 years (1824-1886) and incorporated it into its Indian Empire. Burma was administered as a province of India until 1937 when it became a separate, self-governing colony; independence outside of the Commonwealth was attained in 1948. Gen. NE WIN dominated the government from 1962 to 1988, first as military ruler, then as president, and later as political kingmaker. Despite multiparty elections in 1990 that resulted in the main opposition party winning a decisive victory, the ruling military junta refused to hand over power. Key opposition leader and Nobel Peace Prize recipient AUNG SAN SUU KYI, under house arrest from 1989 to 1995, was again placed under house detention from September 2000 to May 2002 and again in May 2003; her supporters are routinely harassed or jailed. |

Economic aid - recipient | $31.9 million in December 2000 under the HIPC program (2005) | $99 million (FY98/99) |
Economy - overview | This small, poor island economy has become increasingly dependent on cocoa since independence in 1975. Cocoa production has substantially declined in recent years because of drought and mismanagement, but strengthening prices helped boost export earnings in 2003. Sao Tome has to import all fuels, most manufactured goods, consumer goods, and a substantial amount of food. Over the years, it has had difficulty servicing its external debt and has relied heavily on concessional aid and debt rescheduling. Sao Tome benefited from $200 million in debt relief in December 2000 under the Highly Indebted Poor Countries (HIPC) program, which helped bring down the country's $300 million debt burden. In August 2005, Sao Tome signed on to a new 3-year IMF Poverty Reduction and Growth Facility (PRGF) program worth $4.3 million. Considerable potential exists for development of a tourist industry, and the government has taken steps to expand facilities in recent years. The government also has attempted to reduce price controls and subsidies. Sao Tome is optimistic about the development of petroleum resources in its territorial waters in the oil-rich Gulf of Guinea, which are being jointly developed in a 60-40 split with Nigeria. The first production licenses were sold in 2004, though a dispute over licensing with Nigeria delayed Sao Tome's receipt of more than $20 million in signing bonuses for almost a year. Real GDP growth exceeded 4% in 2006, as a result of increases in public expenditures and oil-related capital investment. | Burma is a resource-rich country that suffers from abject rural poverty. The military regime took steps in the early 1990s to liberalize the economy after decades of failure under the "Burmese Way to Socialism", but those efforts have since stalled. Burma has been unable to achieve monetary or fiscal stability, resulting in an economy that suffers from serious macroeconomic imbalances - including a steep inflation rate and an official exchange rate that overvalues the Burmese kyat by more than 100 times the market rate. In addition, most overseas development assistance ceased after the junta suppressed the democracy movement in 1988 and subsequently ignored the results of the 1990 election. Burma is data poor, and official statistics are often dated and inaccurate. Published estimates of Burma's foreign trade are greatly understated because of the size of the black market and border trade - often estimated to be one to two times the official economy. |
