Background | Civil war has been the norm in Angola since independence from Portugal in 1975. A 1994 peace accord between the government and the National Union for the Total Independence of Angola (UNITA) provided for the integration of former UNITA insurgents into the government and armed forces. A national unity government was installed in April of 1997, but serious fighting resumed in late 1998, rendering hundreds of thousands of people homeless. Up to 1.5 million lives may have been lost in fighting over the past quarter century. The death of insurgent leader Jonas SAVIMBI in 2002 and a subsequent cease-fire with UNITA may bode well for the country. | In 1975, the Communist Pathet Lao took control of the government, ending a six-century-old monarchy. Initial closer ties to Vietnam and socialization were replaced with a gradual return to private enterprise, a liberalization of foreign investment laws, and the admission into ASEAN in 1997. |

Economy - overview | Angola has been an economy in disarray because of a quarter century of nearly continuous warfare. An apparently durable peace was established after the death of rebel leader Jonas SAVIMBI on February 22, 2002, but consequences from the conflict continue including the impact of wide-spread land mines. Subsistence agriculture provides the main livelihood for 85% of the population. Oil production and the supporting activities are vital to the economy, contributing about 45% to GDP and more than half of exports. Much of the country's food must still be imported. To fully take advantage of its rich natural resources - gold, diamonds, extensive forests, Atlantic fisheries, and large oil deposits - Angola will need to continue reforming government policies. While Angola made progress in bringing inflation down further, from 325% in 2000 to about 106% in 2002, the government has failed to make sufficient progress on reforms recommended by the IMF such as increasing foreign exchange reserves and promoting greater transparency in government spending. Increased oil production should bring about 6% GDP growth in 2003. | 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 7% in 1988-2001 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. Electricity is available in only a few urban areas. Subsistence agriculture accounts for half of GDP and provides 80% of total employment. The economy will continue to benefit from aid from the IMF and other international sources and from new foreign investment in food processing and mining. |
