I am not Chinese but I still find this comment hilariously offensive and tone-deaf. I can say almost without a doubt that the US has a "tremendous" issue with cult-of-personality right now. But I don't see Chinese or other countries attacking or trying to "contain" this.

The US is still treated as a nation, unified in its people and leaders, by even its adversaries. But when Americans deal with other countries, there is a tendency to say things to the effect of: "the people are fine, it is the X that must be suppressed", ignoring that this X is inherently or directly connected to people of this nation.
