Neither Russia nor China are all that strong. They both need to be careful in their actions or else their domestic situations will spiral out of control. And Europe, of course, is in trouble.

Simple math implies that a share of those accumulated surpluses worth more than 200% of Russia’s current national income has disappeared. Considering the steady annual returns that would likely have been earned on those investment, the economists put the total missing foreign wealth on the order 300% of Russia’s current national income, or more.
