China's growth is almost all but assured. The greatest risks to China come from within, however.
I have posted this before,but the current incarnation of the communist party's hold on power is somewhat tenacious and could potentially be lost if the people stop supporting them.. The replacement would be considerably more hard-line and in such an instance, I'd probably be happy with whatever of my money I could pull out of there before the value of my investment went to zero.
From a geo-political perspective, US-China business & investment relationships probably do more to prop up the current moderates allowing them to build new infrastructure ad housing with jobs for their population. There is a definate trickle-down effect as some savings is returned to the rural dwellers by their children
Finally, the new generation of party members are hardly idealogues, self-admittedly.
Which means that they are a lot like US..
