Sorry, I may not have expressed myself clearly earlier, which led to some misunderstanding.
What I meant is that, according to rumors, the formal or possible charge is long-term leakage of classified information. This may not necessarily be the real reason. If I had to speculate, the underlying reason could be that the current leadership is not fully satisfied with the previous military-industrial modernization model associated with Yang Wei, or that Yang Wei’s continued presence and influence may now be hindering the kind of modernization the current leadership wants to pursue.
People at that level generally have little possibility of leaking secrets to hostile forces. Secondly, a chief designer is closer to being a project leader rather than a top technical specialist. At that level, the role is more about planning, exploring, and adjusting the path toward military-industrial modernization.
Perhaps there is no single, definitive model or path to modernization. Even a relatively successful model is constantly evolving and changing. The leaders who explore such a path would themselves have uncertainties and concerns about the future at the time.
In any case, what is more worth paying attention to and reflecting on is: what kind of military-industrial modernization is actually “good”? And what does “good” mean for different stakeholders? The interests of enterprises, the military, the party, and other actors are neither mutually exclusive nor completely aligned.
