Because of its location in the path of major sea routes, Sri Lanka is a strategic naval link between West Asia and South East Asia, and has been a center of Buddhist religion and culture from ancient times. It became independent in 1948 and its name was changed to Sri Lanka in 1972. Although suffering a brutal civil war that began in 1983, Sri Lanka saw GDP growth average 4.5% in the last 10 years with the exception of a recession in 2001. In late December 2004, a major tsunami took about 31,000 lives, left more than 6,300 missing and 443,000 displaced, and destroyed an estimated $1.5 billion worth of property. Growth, partly spurred by reconstruction, reached 5% in 2005 and more than 6% in 2006. Sri Lanka's most dynamic sectors now are food processing, textiles and apparel, food and beverages, port construction, telecommunications, and insurance and banking. In 2005, plantation crops made up only about 15% of exports (compared with more than 90% in 1970), while textiles and garments accounted for more than 60%. About 800,000 Sri Lankans work abroad, 90% in the Middle East. They send home more than $1 billion a year. The struggle by the Tamil Tigers of the north and east for an independent homeland continues to cast a shadow over the economy.
