Crises, bubbles and capital inflow

Reinhart and Rogoff assess the anatomy of a financial crisis.

“Systemic banking crises are typically preceded by asset price bubbles, large capital inflows and credit booms, in rich and poor countries alike”

The interest that I have is, how far is this explained by the inflow of capital from China and the commodity exporters? What I need to do is look at the evidence of capital inflow and compare this with what happened to the US, UK and others like Iceland.
