In 1999 Angola exported a total of US$5 billion worth of goods and services and imported US$3 billion worth. Due to Angola's colonial past, its primary trading partner has historically been Portugal. Today, Portugal is still a primary trading partner from which 20 percent of Angola's commodities are imported. The United States and South Africa are other major sources of imports for Angola, providing 17 percent and 10 percent, respectively. However, the United States is the major source of Angolan exports with 63 percent of all exports; 9 percent of exports going to the Benelux countries (Belgium, the Netherlands, and Luxembourg), and China, Chile, and France are also important sources of exports.
