While there is little doubt that the emerging economies present the best chances for economic growth, not all countries will prosper at the same rate, says the Wealth Report 2012 by Knight Frank & Citi Private Bank

The International Monetary Fund predicts emerging economies will expand by 5.4 per cent this year and 5.9 per cent next year.

While this certainly marks a significant downgrade from previous forecasts, it still outpaces the average GDP growth of 1.2 per cent and 1.9 per cent expected this year and next year in advanced economies.

Citi research shows that while China and India are likely to grow rapidly over the next 40 years, there are other key countries with promising chances for growth.
