This small, wealthy economy encompasses a mixture of foreign and domestic entrepreneurship, government regulation, welfare measures, and village tradition. Crude oil and natural gas production account for nearly half of GDP. Per capita GDP is far above most other Third World countries, and substantial income from overseas investment supplements income from domestic production. The government provides for all medical services and subsidizes rice and housing. Brunei's leaders are concerned that steadily increased integration in the world economy will undermine internal social cohesion, although it became a more prominent player by serving as chairman for the 2000 APEC (Asian Pacific Economic Cooperation) forum. Plans for the future include upgrading the labor force, reducing unemployment, strengthening the banking and tourist sectors, and, in general, further widening the economic base beyond oil and gas.
