Brunei is a country with a small, wealthy economy that is a mixture of foreign and domestic entrepreneurship, government regulation and welfare measures, and village tradition. It is almost totally supported by exports of crude oil and natural gas, with revenues from the petroleum sector accounting for over half of GDP. Per capita GDP is high, and substantial income from overseas investment supplements income from domestic production. The government provides for all medical services and subsidizes food and housing. The government has shown progress in its basic policy of diversifying the economy away from oil and gas.
