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. Although independence was achieved in 1975, democratic reforms were not instituted until the late 1980s. Though 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 is likely to have a significant impact on the country's economy. | Britain conquered Burma over a period of 62 years (1824-86) 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; her supporters are routinely harassed or jailed. |

Economic aid - recipient | $200 million in December 2000 under the HIPC program | $99 million (FY98/99) |
Economy - overview | This small poor island economy has become increasingly dependent on cocoa since independence 28 years ago. Cocoa production has substantially declined in recent years because of drought and mismanagement, but strengthening prices brighten prospects for 2003. Sao Tome has to import all fuels, most manufactured goods, consumer goods, and a substantial amount of food. Over the years, it has been unable to service its external debt and has had to depend 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. Sao Tome's success in implementing structural reforms has been rewarded by international donors, who pledged increased assistance in 2001. 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 that substantial petroleum discoveries are forthcoming in its territorial waters in the oil-rich waters of the Gulf of Guinea; production could begin as early as 2004. | 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 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. |
