Tourism, petroleum refining, and offshore finance are the mainstays of the Netherlands Antillean economy, which is closely tied to the outside world. The islands enjoy a high per capita income and a well-developed infrastructure as compared with other countries in the region. Almost all consumer and capital goods are imported, with Venezuela, the US, and Mexico being the major suppliers. Poor soils and inadequate water supplies hamper the development of agriculture. The Netherlands provides financial aid to support its economy.
