IMF has said the signs of revival in the global economy should not be confused with the financial crisis being over and the countries should be ready with policies to sustain the recovery. While releasing the World Economic Outlook in New Delhi on Friday, IMF Chief Economist, Olivier Blanchard said the current numbers should not fool governments into thinking that the crisis is over. He also asked countries around the world to coordinate policies to achieve a global rebalancing and sustain the recovery. Olivier's remarks assume importance in view of G-20 nations agreeing not to withdraw stimulus packages prematurely. IMF in its outlook for the global economy has said that global activity is now on the rise again. However, the world economic growth is expected to be in the negative zone of 1.1 per cent in 2009, according to IMF. The global economic growth is expected to reach 3 per cent by next year.
