FDI (Foreign Direct Investment) is a stable indicator of growth of an economy. Because it’s defined as long term investment. Foreign Direct Investors buy land and construct plants and offices or they buy shares of already existed foreign corporates to hold shares for a long term.

FDI volume indicates a confidence level of relevant country economy. Simply it depends on investors expectations. As I know China attracks most of FDI in the World. So, China is most rapidly growing economy in the World with about 10% annual growth rate. If we take population of China into account, it’s not hard to say that in one day China will be biggest economy of the World. All countries of the World see the success of China and struggle to increase their shares in the total FDI pie of the World.
