> What do you mean by that?
By that I mean that there's no need to trace ownership to the trade union and conclude that because independent trade unions aren't allowed, the company can't be independent either. You could just go straight to Article 17 of the Company Law of the People's Republic of China [1], which reads
"The grass-root organizations of the Communist Party of China in companies shall carry out their activities in accordance with the Constitution of the Communist Party of China."
So no Chinese company could possibly be independent, trade union or not. That's on paper anyway. In practice, Chinese companies undermine each other and government agencies all the time, instead of harmoniously cooperating to fulfill the CCP's grand plan. Similarly, membership in the ACFTU doesn't tell you anything about the actual power dynamics.
