The Maldives is a founding member of the South Asian Association for Regional Cooperation (SAARC). It is also a member of the United Nations, the Commonwealth of Nations, the Organization of Islamic Cooperation and the Non Aligned Movement. Along with Sri Lanka, the Maldives is one of two South Asian countries rated "high" on the Human Development Index (HDI). Its per capita income is the highest among SAARC nations.
The Maldivian economy is to a large degree based on tourism. The Maldives' largest industry is tourism, accounting for 28% of GDP and more than 60% of the Maldives' foreign exchange receipts. Fishing is the second leading sector. Agriculture and manufacturing continue to play a lesser role in the economy, constrained by the limited availability of cultivable land and the shortage of domestic labour. Tourism gave a major boost to the country's fledgling traditional cottage industries such as mat weaving, lacquer work, handicraft, and coir rope making. New industries that have since emerged include printing, production of PVC pipes, brick making, marine engine repairs, bottling of aerated water, and garment production.
