China is working very hard to convince people that Sars-CoV-2 did not originate in China.

It is foolish to politicize the place of origin of the virus. This campaign by China is foolish, just as the bullshitter's castigation of China because the virus originated there is foolish.

What China did wrong was to deny for a time that it had detected Sars-CoV-2. But that did not last very long. Many other countries have done much worse things in dealing with Covid-91, including the US.
