The World Trade Organization reached deals on agricultural export subsidies, food aid and other issues on Saturday, capping a ministerial conference in the Kenyan capital where rich and poor countries had been split over the path of trade reform. Members said the Nairobi deal had drawn a line under years of stalemate over the direction of global trade negotiations. “Our work in Nairobi marks a turning point for the World Trade Organization,” U.S. Trade Representative Michael Froman said in a statement.
