BERLIN (AP) — The World Trade Organization has sharply reduced its forecast for global trade growth this year, pointing to uneven economic growth in countries including China and the U.S.

The WTO said Tuesday that its economists are now predicting 3.1 percent growth in world trade this year, down from the 4.7 percent forecast in April. They also cut their outlook for 2015 to 4 percent from the previous 5.3 percent.
