Djibouti has a market-based, free-enterprise economy. The economy is based on service activities connected with the country's strategic location and status as a free trade zone in northeast Africa. Its economic development depends largely on foreign investment and aid. Djibouti's income originates from its port, railway terminus, government administration, airport and construction industry. It has few natural resources and little industry. The main exports are hides and skins, cattle, and coffee (transshipped from Ethiopia). Djibouti imports foods and beverages, transportation equipment, chemicals, and petroleum products. The main trading partners are Somalia, Ethiopia, Saudi Arabia, India, and China.
