Economy Indonesia Economy Crude oil and natural gas are Indonesia's most valuable natural resources and its major source of export revenue. Nearly all of the country's oil and gas deposits are located on Sumatra. Horses and cattle are raised on some of the Lesser Sunda Islands.
Fish are abundant, both in the ocean and in inland ponds.
In natural-resource potential, Indonesia is one of the wealthiest countries in the world. Palm, rattan, and bamboo abound, and a great variety of forest products is produced. Indonesia is a major exporter of timber, accounting for nearly half of the world's tropical hardwood trade.

Tin, bauxite, nickel, coal, manganese, copper, gold, and silver are mined, and salt is available in large quantities from shallow enclosed seashore lagoons.
