This article reports on the emergence of trade agreements between the United States and countries in Africa. Though Africa accounts for barely 2% of world trade, Mr Zoellick (Robert Zoellick) is giving it some serious attention in his two-week world tour. Negotiations for a trade deal between America and the Southern African Customs Union (SACU, composed of South Africa, Botswana, Lesotho, Namibia and Swaziland) began a year ago, but start in earnest on February 23rd. Tariff-free exports of some 6,000 goods from Africa to the United States are boosting trade and investment in southern Africa. American drugs firms want to be part of the fast expansion in South Africa of production of anti-retroviral drugs, used against AIDS. But Mr Zoellick's greater concern is for multilateral trade talks that stalled in Cancún, Mexico, in September. So Mr Zoellick is trying to charm his African partner by agreeing to drop support for most of a group of issues (known as "Singapore" issues) that jammed up the talks at Cancún, and were opposed by poor countries. Even though America has treated Africa very shabbily on trade in the past, Mr Erwin (Alec Erwin) hints it is easier doing business with America than with Europe or Japan.
