I hope the responses from some of our Chinese members here are not indicative of how their leadership view things.
When the stakes are so high, as high as economic control of the world, one cannot underestimate even the smallest of threats, let alone an adversary as devious as the west is, a nation in China's current position can never be careful enough.
The main utility of wealth is 'control', so its control what matters, wealth is just 'one' of many means to it, if the only way to maintain 'control' is to accept grave damages in wealth, infrastructure, lives or any other aspect, the west will take it, because control is all that matters to the ruling class, whatever and whomever it is composed of.
This does not mean that any particular scenario suggested in here is how things will play out, but even a rapid look at western historical behavior will tell you that something is being cooked for China.
