I wouldn't be so sure. As we've seen with "the Big Guy" who gets his 10% cut of everything it seems, China does a damn' good job of buying people off or compromising them to guarantee that they (China) gets what it wants.
No matter who they bribe, there are technological impediments they can’t overcome. China simply doesn’t have the ability to make these kinds of chips on the same process (which means the physical size of the chip) that the big boys can.
Building competent CPU fabs is difficult and expensive and even when done right, the ‘spoilage’ from the process - which is to say the percentage of chips from each wafer that simply don’t work because of manufacturing defects - is reasonably high. Because of this, and other reasons, it’s simply not economically feasible to ‘fake’ one of these sophisticated chips.
