Oh you’ve gone straight to the Chinese—I figured you were running off of the various English-language analyses floating around. Huawei’s ownership became a political football a while back, so there’s a fair bit of decent English content on it.

Huawei is a good example of how legal categories can be a little misleading—if Chinese lawyers are anything like English ones, they’ll use whatever legal structure gives the most advantage. For instance, I can’t tell which category SAIC would fall under. On one hand, Wikipedia calls it a state-owned entity, and the state asset commission has a controlling stake. On the other hand, it’s a limited liability company, it’s a joint-stock corporation, and it has multiple joint-venture subsidiaries.

The follow up question, of course, would be why structures other than cooperatives would be preferred, and it’s not one I’ve read widely enough to be able to answer.
