Background | 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. | First colonized by the Spanish, the islands came under British control in the early 19th century. The islands' sugar industry was hurt by the emancipation of the slaves in 1834. Manpower was replaced with the importation of contract laborers from India between 1845 and 1917, which boosted sugar production as well as the cocoa industry. The discovery of oil on Trinidad in 1910 added another important export. Independence was attained in 1962. The country is one of the most prosperous in the Caribbean thanks largely to petroleum and natural gas production and processing. Tourism, mostly in Tobago, is targeted for expansion and is growing. The government is coping with a rise in violent crime. |

Disputes - international | Southeast Asian states have enhanced border surveillance to check the spread of avian flu; talks continue on completion of demarcation with Thailand but disputes remain over several areas along Mekong River and Thai squatters; concern among Mekong Commission members that China's construction of dams on the Mekong River will affect water levels | in April 2006, the Permanent Court of Arbitration issued a decision that delimited a maritime boundary with Trinidad and Tobago and compelled Barbados to enter a fishing agreement that limited Barbadian fishermen's catches of flying fish in Trinidad and Tobago's exclusive economic zone; in 2005, Barbados and Trinidad and Tobago agreed to compulsory international arbitration under UNCLOS challenging whether the northern limit of Trinidad and Tobago's and Venezuela's maritime boundary extends into Barbadian waters; Guyana has also expressed its intention to include itself in the arbitration as the Trinidad and Tobago-Venezuela maritime boundary may extend into its waters as well |
Economic aid - recipient | $243 million (2001 est.) | $200,000 (2007 est.) |
Economy - overview | 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% in 1988-2004 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 food processing and mining. Construction will be another strong economic driver, especially as hydroelectric dam and road projects gain steam. In late 2004, Laos gained Normal Trade Relations status with the US, allowing Laos-based producers to face lower tariffs on exports. This new status may help spur growth. In addition, the European Union has agreed to provide $1 million to the Lao Government for technical assistance in preparations for WTO membership. If the avian flu worsens and spreads in the region, however, prospects for tourism could dim. | Trinidad and Tobago has earned a reputation as an excellent investment site for international businesses and has one of the highest growth rates and per capita incomes in Latin America. Recent growth has been fueled by investments in liquefied natural gas (LNG), petrochemicals, and steel. Additional petrochemical, aluminum, and plastics projects are in various stages of planning. Trinidad and Tobago is the leading Caribbean producer of oil and gas, and its economy is heavily dependent upon these resources but it also supplies manufactured goods, notably food and beverages, as well as cement to the Caribbean region. Oil and gas account for about 40% of GDP and 80% of exports, but only 5% of employment. The country is also a regional financial center, and tourism is a growing sector, although it is not proportionately as important as in many other Caribbean islands. The economy benefits from a growing trade surplus. Economic growth reached 12.6% in 2006 and 5.5% in 2007 as prices for oil, petrochemicals, and LNG remained high, and as foreign direct investment continued to grow to support expanded capacity in the energy sector. |
