The International Monetary Fund (IMF) has said that India's economic growth rate will accelerate to 6.5 per cent in 2010 on account of robust domestic demand and rising private investment. The regional economic outlook released by the IMF said, the normalisation of financial conditions is expected to support a rebound of private investment, sustaining demand even as the fiscal stimulus is withdrawn. The IMF said, emerging Asia, in particular China and India are rebounding much more quickly than the western world.
