FRANKFURT (AFX) - The danger of a recession in the U.S. still remains, International Monetary Fund chairman Horst Koehler said in an interview with German daily Frankfurter Allgemeine Zeitung. "Up until now we have been expecting a swift economic recovery, but this depends to a large extent on the development of investment activity over the next two months," Koehler said. The recent good U.S. GDP figures should be greeted with caution, since investment activity remains very weak, he said.
