Modern-day Laos has its roots in the ancient Lao kingdom of Lan Xang, established in the 14th century under King FA NGUM. For 300 years Lan Xang had influence reaching into present-day Cambodia and Thailand, as well as over all of what is now Laos. After centuries of gradual decline, Laos came under the domination 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, limited return to private enterprise and the liberalization of foreign investment laws began in 1988. Laos became a member of ASEAN in 1997 and the WTO in 2013.
The government of Laos, one of the few remaining one-party communist states, began decentralizing control and encouraging private enterprise in 1986. Economic growth averaged more than 6% per year in the period 1988-2008, and Laos' growth has more recently been amongst the fastest in Asia, averaging nearly 8% per year for most of the last decade. However, growth has declined over the past year and is expected to be about 6.8% in 2017, according to the IMF.Nevertheless, Laos remains a country with an underdeveloped infrastructure, particularly in rural areas. It has a basic, but improving, road system, and limited external and internal land-line telecommunications. Electricity is available to 83% of the population. Agriculture, dominated by rice cultivation in lowland areas, accounts for about 25% of GDP and 73% of total employment. Recently, the country has faced a persistent current account deficit, falling foreign currency reserves, and growing public debt, as slow recovery of the global economy, especially that of China, has driven down the prices of its mineral exports.Laos' economy is heavily dependent on capital-intensive natural resource exports. The economy has benefited from high-profile foreign direct investment in hydropower dams along the Mekong River, copper and gold mining, logging, and construction, although some projects in these industries have drawn criticism for their environmental impacts.Laos gained Normal Trade Relations status with the US in 2004 and applied for Generalized System of Preferences trade benefits in 2013 after being admitted to the World Trade Organization earlier in the year. Laos held the chairmanship of ASEAN in 2016. Laos is in the process of implementing a value-added tax system. The government appears committed to raising the country's profile among foreign investors and has developed special economic zones replete with generous tax incentives, but a limited labor pool, a small domestic market, and corruption remain impediments to investment. Laos also has ongoing problems with the business environment, including onerous registration requirements, a gap between legislation and implementation, and unclear or conflicting regulations.
