As I see things, China has the ability to fix its own problems through its own unified fiscal and monetary approach.
Europe has major problems and does not have a unified fiscal approach that is being actively implemented by all Eurozone countries. Germany will have to backstop and supply monetary support in some fashion if it truly wants to see all countries remain in the Euro. Otherwise, countries who do not wish to continue under the European Stability Mechanism (ESM) rules will leave the Euro…simple as that.
