You obviously don't have much experience with China. China is an authoritarian state and all companies are subject to secret control by the state, essentially branches of the military. There is no legal recourse or protection from such intervention. The government can mandate spy code be inserted and any data they want.
You're well intended here, but ignorant of how China operates. There is literally no way to enforce what you suggest.
