India holds great promise, at a time when advanced economies are struggling with low growth and deflation, but growth in the country is “not inevitable”, he said. “When we grew at nine plus per cent before the global financial crisis from 2003 to 2008, there was very high investment. Again, after the crisis, growth dropped because investment dropped. Today, there is no investment taking place. So, unless investment is jacked up, it is difficult to accelerate growth,” Rao said at a meeting here on Monday.
