No.
In fact the complete opposite, you (and us Europeans) need China to survive as economic powers. Probably 50% of our manufacturing is outsourced to China, it's the bulk of their economy and ours is reliant on it's produce to make our designs.
If one side or the other stops we're both well and truly fucked in economic terms, China will have nothing to sell, we will have nothing for them to make.
You don't have to like them, but it's the nature of world economics now that China, Europe, the US, far east Asia and India need each other's business to keep their respective economies running. Threat nothing, we need them.
As a different point American industry needs to change if it wants to stay a world power or suffer a UK seventies and eighties style slump. Your factories are over unionised and the technology is becoming extremely outdated. This is no more apparent than in US made cars, they've become synonymous with poor quality outdated and under engineered designs. But the massive chunks of dead industry that need to be hacked out are being held in place by Government funding and the threat of industrial action. Until that changes US industry is going to keep declining and hemoraging money. That's a bigger threat than China.
