The government of Laos, one of the few remaining one-party 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 from 1988-2008 except during the short-lived drop caused by the Asian financial crisis that began in 1997. Despite this high growth rate, Laos remains a country with an underdeveloped infrastructure, particularly in rural areas. It has a rudimentary, but improving, road system, and limited external and internal telecommunications. China has signed a deal with the Lao to build a high speed rail system in the country. Construction on the $7 billion project is slated to begin in April 2011 and will take five years. Electricity is available in urban areas and in many rural districts. Subsistence agriculture, dominated by rice cultivation in lowland areas, accounts for about 30% of GDP and 75% of total employment. The government in FY09/10 received $586 million from international donors. Economic growth has reduced official poverty rates from 46% in 1992 to 26% in 2010. The economy has benefited from high foreign investment in hydropower, mining, and construction. Laos gained Normal Trade Relations status with the US in 2004, and is taking steps required to join the World Trade Organization, such as reforming import licensing. Related trade policy reforms will improve the business environment. On the fiscal side, Laos initiated a VAT tax system in 2010. Simplified investment procedures and expanded bank credits for small farmers and small entrepreneurs will improve Lao's economic prospects. The government appears committed to raising the country's profile among investors. The World Bank has declared that Laos's goal of graduating from the UN Development Program's list of least-developed countries by 2020 is achievable. According Laotian officials, the 7th Socio-Economic Development Plan for 2011-15 will outline efforts to achieve Millennium Development Goals.
