China is starting to remind me a little like Japan economically. There was a time when the fear was that Japan was buying every company and building in the US that they could get their hands on.
Over stimulating their economy caused damage that is still being felt today. While certainly China is much larger, if their bubble pops, it is going to pop with a much larger bang.
Now that the Chinese people have gotten a small taste of freedom, they are going to be demanding more. There’s no telling what spark will set the people off. Being so vast, with so many ethnic regions, they are going to have a tough time controlling it all.
