- Economy Overview: The Indian Ocean provides a major transportation highway for the movement of petroleum products from the Middle East to Europe and North and South American countries. Fish from the ocean are of growing economic importance to many of the bordering countries as a source of both food and exports. Fishing fleets from the USSR, Japan, Korea, and Taiwan also exploit the Indian Ocean for mostly shrimp and tuna. Large reserves of hydrocarbons are being tapped in the offshore areas of Saudi Arabia, Iran, India, and Western Australia. An estimated 40% of the world's offshore oil production comes from the Indian Ocean. Beach sands rich in heavy minerals and offshore placer deposits are actively exploited by bordering countries, particularly India, South Africa, Indonesia, Sri Lanka, and Thailand.
Industries: based on exploitation of natural resources, particularly marine life, minerals, oil and gas production, fishing, sand and gravel aggregates, placer deposits
