Yes I'm well aware of the constantly reiterated technicality that Foxconn is a Taiwanese company.

They're a Chinese company. Period. If China believed differently, they wouldn't be allowed to do what they do in domestic China.

China is nationalistic first, concerned with money second. That has always been the case and will always be the case. There's no amount of money that can buy you a lot of segments in their country; there are countless monster companies locked out of China right now, who would willingly pay countless billions just to get proper access to their markets - China promotes their domestic giants first, always.
