Doesn't really matter WHERE they are located. So long as it is owned and controlled by Chinese , then China will still have control over it.
Why? Because these owners will likely have interests/properties/businesses IN China. Heck, if it is for the country, and the pressure is high enough, well.
When I worked as an interpreter with big Chinese companies (thousands of workers, just in case), the groups that we were negotiating with always had some guy sticking around them, who didn't participate in discussions and business negotiations, but nevertheless was always present at these meetings. When we asked in private who was that guy and what he was doing there, we were told that he is "representing the government". Between ourselves we concluded that he was actually an agent of some government security service supervising the company deals and contacts. I guess you strongly underestimate the level of government participation in businesses across China
