AFRICA South of the Sahara became so marginalised during the 1980s that its share of world trade fell from 3·8 per cent in 1960 to 1·05 per cent in 1989. And it has attracted relatively little foreign investment, with the exception of a few exporters of petroleum: only 2,000 million US dollars in 1995 corresponding to 2 per cent of the total for developing countries. Indeed, the continent's share (including North Africa) declined from 11 per cent in 1986–90 to 4 per cent in 1994.
