This has nothing to do with lab leak theory. This is what China actually did. They think in terms of comparison with other countries and they didn’t want to be the only country with covid, regardless of the origin.

Maybe they’ll do the same thing as China. Leaving their international airports functional while locking down their cities, intentionally infecting as many places as possible. And then legit Xi goes on air to scold other nations telling them they need to learn how to do international cooperation.

Everything was closed in Wuhan except outbound international flights.
