China has no real bureaucracy (or any other structure for that matter) because at the end of the day, it's one guy who can do whatever he wants whenever he wants. For commoners and officials there is this faux bureaucracy, but for the elite at the top making decisions, there is zero.
If Xi doesn't want models exported, he's not having a legal delegation go to the supreme court of China to fight for his ruling. It just happens, regardless of whatever anyone else or any piece of paper in the country says, and there is zero recourse anyone who doesn't like it can pursue.
The Ten Eunuchs, if you want one example. Which is to say, their bureaucracies have always worked with single leaders who ostensibly had unilateral uncontested control for life. https://en.wikipedia.org/wiki/Ten_Attendants
