Bahrain is a well-known offshore banking centre and international and regional inter-bank money market. Production of oil and natural gas and refinement of petroleum are also major economic activities in Bahrain. Industrialisation and private sector investment in sectors such as tourism are encouraged. The majority of Bahrain’s food is imported, but agriculture also contributes to the local food supply. Dates, bananas, mangoes, and vegetables are the main crops. The traditional industries of Bahrain are dhow (Arab sailboats) construction, fishing, pearling, and the manufacture of reed mats.
