Yes, there are certainly similarities between the USSR and China. But if we are to be objective and fact-oriented here, comparing China today to the USSR in the 80s and its response to this epidemic to the USSR's in Chernobyl, is a big stretch.
You are reading my comment in a shortsighted way. Note how the second part of the sentence mentions the US under GWBush - obviously I'm not arguing 2000s US and 2020s China are similar in political or economic structure. The point is how political consensus with fascist characteristics, that had looked unbreakable until then, can quickly be upended by crisis when the system is shown as uncapable to guarantee personal safety.
