The Dominican Republic is based on agriculture. Although the country has long been viewed primarily as an exporter of sugar, coffee, and tobacco, in recent years the service sector has overtaken agriculture as the economy's largest employer, due to growth in tourism and free trade zones. There are deposits of nickel, bauxite, gold, silver, and other minerals, and mining is of growing economic importance. The country exports free-trade-zone manufactured products (garments, medical devices, etc.), nickel, sugar, coffee, cacao, and tobacco. It imports petroleum, industrial raw materials, capital goods, and foodstuffs.
