Angola is the second largest oil producer in Sub-Saharan Africa. The oil sector thrived over the years by escaping government nationalization and was shielded from the war because of the coastal location of most refineries. It is difficult to break into the oil sector. A handful of foreign companies control the oil industry. There is little reinvestment back into the Angolan economy.
Fishing is another profitable export.
The government exercises little or no control over foreign companies engaged in coastal fishing. The industry is closely guarded by current incumbents and is difficult to break into. Entering into diamond trade is another risky venture, unless safe trade routes and contact persons can be established. The government uses almost all of its revenues in defense and paying for imports, which are needed to sustain the country each year. Agriculture is a promising sector for investing in.
