Real exports of developing economies more than doubled between 1998 and 2006,whereas those of the G-7 rose by less than 50 percent. Among the developing regions, East and South Asia were clearly the most successful in increasing exports (by volume), at rate of about 160 percent, despite a deterioration in their terms of trade. In other developing regions,export volumes grew at a more moderate pace,close to that of the G-7,but gains from the terms of trade boosted the purchasing power, and consequently their imports. Overall, the share of developing countries in global trade rose from 29 percent in 1996 to 37 percent in 2006.
