Trade: Developing countries as a whole have increased their share of world trade–from 19 percent in 1971 to 29 percent in 1999. But Chart 2b shows great variation among the major regions. For instance, the newly industrialized economies (NIEs) of Asia have done well, while Africa as a whole has fared poorly. The composition of what countries export is also important. The strongest rise by far has been in the export of manufactured goods. The share of primary commodities in world exports—such as food and raw materials—that are often produced by the poorest countries, has declined.
