AFAIU the crackdown in Hong Kong was predicated on a seemingly Mozi-like argument. From Wikipedia: "Some believe the best descriptor to be state consequentialism. According to this reading, Mohist ethics makes moral evaluations based on how well the action, statement, etc., in question contributes to the stability of a state. Such state-related goods include social order, material wealth, and population growth."

In other words, the protests were threatening not only the stability of the parent Chinese state, but in their duration and severity even the stability of Hong Kong itself. In doing so, the protesters were being selfish and indulgently individualistic. At least, that's the argument the Chinese leadership regularly put forth.
