Like pretending it was an unknown disease that showed no sign of person-to-person spread when they'd already sequenced its entire RNA and found cases of it spreading within the community. Like having to be pressured into revealing what little details they did. Like, as I recall, only admitting that it was spreading person-to-person when another country spotted this. That kind of not sharing information.
When people dislike a certain government or person, they jump to the worst conclusions about them rather quickly. This is extremely dangerous. Imagine a sensitive situation develops where there's weak evidence the victim of your dislike did something that might endanger you or your country... if you immediately jump to conclusions, which you are very likely to do as this thread shows, then the situation would easily develop into a confrontation... this is not hypothetical. With Americans and Chinese (and Russians, Iranians) coming face-to-face in more and more sensitive situations around the world, it's only a matter of time until the mutual distrust will cause one side to pull the trigger under unreasonable circumstances.
