ROCCA DI PAPA, Italy (AFP) - The US economys return to growth is good news, IMF chief Dominique Strauss-Kahn said Friday, while predicting that unemployment will continue to rise for up to a year. Growth is coming back, but the delay between growth resuming and unemployment decreasing is something between 10 and 12 months depending on the country, Strauss-Kahn said at the International Labour Festival in Rocca di Papa, southeast of Rome. The US economy pulled out of recession in the third quarter, when output grew at a seasonally adjusted 3.5 percent annual rate. The strongest growth in two years has boosted confidence in a US and global economic recovery. But the head of the International Monetary Fund said Friday: Of course we have to rejoice at this good news, but we should not draw the conclusion we can go back to business as usual.... I dont believe we can declare victory before unemployment decreases. He added: On the contrary we absolutely need to pursue with the stimulus.
