This small, wealthy economy is a mixture of foreign and domestic entrepreneurship, government regulation, welfare measures, and village tradition. Crude oil and natural gas production account for about 90% of its GDP. Oil are produced every day, making Brunei the fourth-largest producer of oil in Southeast Asia.
Substantial income from overseas investment supplements income from domestic production. Most of these investments are made by the Brunei Investment Agency, an arm of the Ministry of Finance. The government provides for all medical services, and subsidises rice and housing.
Brunei depends heavily on imports such as agricultural products (e.g. rice, food products, livestock, etc.), motorcars and electrical products from other countries. Brunei imports 60% of its food requirements, of that amount, around 75% come from the ASEAN countries.
