How does China exert control?

In China, the control exhibited over tech companies is considerable and politically driven. Marc Andreessen recounts an example where if you're the CEO of a Chinese tech company, you are assigned a political officer. This officer can pull you from meetings to study ideologies like Marxism and Xi Jinping's thoughts, and you are expected to pass tests on these subjects.

This is aligned with China's ambition to be the dominant global power 1.
