Defnitely not the official stance, but Lijian Zhao (China Spokesperson & Deputy Director General, Information Department, Foreign Ministry) tweeted "It might be US army who brought the epidemic to Wuhan."
I think it's clearly not a bioweapon, and there would be no benefit to China for releasing it, but it's exactly the sort of thing that lab was investigating, so part of me wonders if there wasn't a leak of a research sample. Even if it were so, I would never blame all Chinese people for it.
Occam's razor is for the obvious, it was a cross species jump of a disease from another animal (in this case a bat). Which happens somewhat regularly, and was already known to be a concern.
Maybe, but I somehow don't feel like their government would have fought to hide as much info about it unless they were embarrassed about something, so I feel like the razor cuts the other way. Can we really trust a government that hid things for so long? That said, I doubt we'll have any real proof one way or another.
He did it because Mike Pompeo keeps calling it the China or Wuhan virus, instead of Covid-19, and it irritates China. Now Trump calls it "China virus" consistently...
There's many ways to debunk Lijian Zhao's conspiracy theory including the fact that the people who participated in the Wuhan military games and admitted to the hospital for an "unknown respiratory illness" was confirmed to be malaria by the hospital itself.
He knows it, and anyone who did brief research knows (there are lots of Chinese who believe it, though...they are the Chinese equivalent to MAGA supporters).
