Bananas, cacao, pineapples, and tobacco are also grown. Tropical timber is exported. Peninsular Malaysia, Sarawak, and Sabah share more or less equally in this form of trade. Malaysia is one of the world's leading tin producers. Like most primary products, tin faces an uncertain future.
Quotas are in force to restrict production.
In 1993 Malaysia produced an estimated 10,000 tons of tin. Petroleum is a more recent industry with reserves estimated at more than 3 billion barrels. Production is almost entirely from offshore rigs that lie to the east of peninsular Malaysia and to the north of Sarawak and Sabah. Production of petroleum reached nearly 450,000 barrels per day in 1984 but was reduced in response to declining prices. The petroleum fields also contain vast reserves of natural gas that have been little exploited.
