Members of the World Trade Organization are poised to select Ngozi Okonjo-Iweala as their next director-general. If confirmed, the 66-year-old Nigerian developmental economist will become the first woman and the first African to lead the WTO. The development comes at a critical moment for the WTO, which is confronting the most turbulent period of its 26-year existence. Backed by the U.S., EU, Japan and China, world leaders hope Okonjo-Iweala can help steer the WTO out of its negotiating morass and make it fit to govern the modern global trading system.
