Failure to chart a viable reform path for the World Trade Organization at a meeting next week will nudge members to pursue other options to set rules and advance free trade, diplomats and officials told Reuters. The four-day gathering of WTO trade ministers in the Cameroon capital Yaounde comes at a critical moment for the 1995 successor body to the General Agreement on Tariffs on Trade (GATT) launched after World War Two to govern world trade. The talks will also take place in the shadow of the U.S.-Israeli war on Iran, which has disrupted global energy supplies and threatens to seriously damage the world economy.
