I think it’s highly likely that the Chinese government downplayed it, hell our own government downplayed it, the American government downplayed it, the Russian government downplayed it, the Brazilian government downplayed etc. Most of these governments continue to downplay it.
Did the Chinese cover it up? To some extent no doubt. But then again we selectively report deaths so we’re covering it up, we lie in parliament about it so we’re covering it up, we have stats that one week that are important and the next irrelevant when they stop painting the “right” picture so we’re covering it up.
Let him without sin cast the first stone.
