Background | Burundi's first democratically elected president was assassinated in October 1993 after only four months in office. Since then, some 200,000 Burundians have perished in widespread, often intense ethnic violence between Hutu and Tutsi factions. Hundreds of thousands have been internally displaced or have become refugees in neighboring countries. Burundian troops, seeking to secure their borders, intervened in the conflict in the Democratic Republic of the Congo in 1998. More recently, many of these troops have been redeployed back to Burundi to deal with periodic upsurges in rebel activity. A new transitional government, inaugurated on 1 November 2001, was to be the first step towards holding national elections in three years. However, the unwillingness of the Hutu rebels to enact a cease fire with Bujumbura continues to obstruct prospects for a sustainable peace. | Modern-day Laos has its roots in the ancient Lao kingdom of Lan Xang, established in the 14th Century under King FA NGUM. For three hundred years Lan Xang included large parts of present-day Cambodia and Thailand, as well as all of what is now Laos. After centuries of gradual decline, Laos came under the control of Siam (Thailand) from the late 18th century until the late 19th century when it became part of French Indochina. The Franco-Siamese Treaty of 1907 defined the current Lao border with Thailand. In 1975, the Communist Pathet Lao took control of the government ending a six-century-old monarchy and instituting a strict socialist regime closely aligned to Vietnam. A gradual return to private enterprise and the liberalization of foreign investment laws began in 1986. Laos became a member of ASEAN in 1997. |

Economy - overview | Burundi is a landlocked, resource-poor country with an underdeveloped manufacturing sector. The economy is predominantly agricultural with roughly 90% of the population dependent on subsistence agriculture. Its economic health depends on the coffee crop, which accounts for 80% of foreign exchange earnings. The ability to pay for imports therefore rests largely on the vagaries of the climate and the international coffee market. Since October 1993 the nation has suffered from massive ethnic-based violence which has resulted in the death of more than 200,000 persons and the displacement of about 800,000 others. Only one in four children go to school, and more than one in ten adults has HIV/AIDS. Foods, medicines, and electricity remain in short supply. Doubts regarding the sustainability of peace continue to impede development. A Geneva donors' conference in November 2001 brought $800 million in pledges, and an IMF-staff-monitored program could lead to a further agreement in 2002. | The government of Laos, one of the few remaining official Communist states, began decentralizing control and encouraging private enterprise in 1986. The results, starting from an extremely low base, were striking - growth averaged 6% per year in 1988-2006 except during the short-lived drop caused by the Asian financial crisis beginning in 1997. Despite this high growth rate, Laos remains a country with a primitive infrastructure. It has no railroads, a rudimentary road system, and limited external and internal telecommunications, though the government is sponsoring major improvements in the road system with possible support from Japan. Electricity is available in only a few urban areas. Subsistence agriculture, dominated by rice, accounts for about half of GDP and provides 80% of total employment. The economy will continue to benefit from aid by the IMF and other international sources and from new foreign investment in hydropower and mining. Construction will be another strong economic driver, especially as hydroelectric dam and road projects gain steam. Several policy changes since 2004 may help spur growth. In late 2004, Laos gained Normal Trade Relations status with the US, allowing Laos-based producers to benefit from lower tariffs on exports. Laos is taking steps to join the World Trade Organization in the next few years; the resulting trade policy reforms will improve the business environment. On the fiscal side, a value-added tax (VAT) regime, slated to begin in 2008, will streamline the government's inefficient tax system. |
