They don't even care about IBM.
They could've bought IBM in one night.
Foxconn alone is 3 times the IBM in simple numbers and makes everything.
Huawei another company that makes the rest of what Foxconn does not make.
IBM is already sold many parts to the chinese, Lenovo being one of them, and the rest are sold here and there.
It's just the rule. They are so important, as a market, that they can even make IBM to obey every rule they want.
