AlQa'dah 25, 1433, Oct 11, 2012, SPA -- The head of the International Monetary Fund Thursday called for action to dispel the uncertainty over policy implementation that is hampering global recovery, UPI reported. Addressing a news conference in Tokyo, the venue of the annual meetings of the World Bank and the IMF, Christine Lagarde said the uncertainty concerned whether policymakers would be able to move forward with their policy commitments. Speaking in the wake of the IMF's downward revision of its forecast for world economic growth, Lagarde said many good decisions have been taken to secure global recovery, but they remain to be put in force. "We need action to lift the veil of uncertainty," she said. "Many of us have debated what actions are needed, many of us understand what needs to be done, but it actually needs to happen." Stressing the need for cooperation, the former finance minister of France said the task of securing sustained recovery has become more complex, involving multiple players. She said new players are emerging on the world scene even as the traditional ones assume different roles. "We really need to go through what needs to be done to make sure that recovery is not just a little bounce but is really here for the longer term and is sustainable'" she urged. On the IMF's forecast revision, Lagarde said development of larger global ripple effects have spread the slowdown to emerging markets, particularly those in Asia. "My message today: Countries need to take courageous and cooperative action to spur a lasting recovery," Lagarde said.
