By "tech" I'm sort of vaguely handwaving at Silicon Valley et al. I agree that China has built up a massive manufacturing industry that the west depends on, but I don't think that "being a significant cog in the machine," so to speak, buys as much influence or bargaining power as being the maker or owner of the machine. It's better to have the Apples and Googles of the world than it is to have the SG Micros or BYD Electronics.
