The overwhelming majority of the population is engaged in subsistence agriculture, although only about 3% of the land is under cultivation. Manioc, yams, millet, corn, and bananas are the main food crops. The principal cash crops and agricultural exports are cotton, coffee, and tobacco; cocoa, rubber, and palm products are raised in the southwest. Timber is also an important export product. Cattle are raised in the western portion of the country.
Diamonds (the leading export), uranium, and gold are mined. Industry is limited to mineral, timber, and food processing and to the production of light consumer goods. Inadequate transportation has been a major obstacle to the country's economic development. Food, textiles, petroleum products, machinery, electrical equipment, motor vehicles, chemicals, and pharmaceuticals are imported. The Central African Republic's chief trading partners are Belgium, France, and the United States. Most exports are shipped via Pointe-Noire, in Congo (Brazzaville), more than 1,100 mi (1,770 km) away.
