The IMF maintained its forecasts for global growth for both 2011 and 2012 at 4.4% and 4.5%, respectively, saying the global recovery was strengthening even though downside risks have risen.The fastest growth was still coming from emerging economies, it said. China was expected to lead the way with growth of 9.6% this year, followed by India`s economy, which was projected to expand 8.2%.By contrast, the United States was forecast to grow at a sub-par 2.8% rate this year and 2.9% in 2012. The IMF expressed concerns that US plans to cut its budget deficit were backsliding and it urged Washington to tackle politically thorny Social Security and tax reforms.
