> Then why would block any investigation from outside the Chinese government? I can easily believe that the Chinese government, not exactly known for its openness, would be keen to block investigations into their bio research labs, regardless of what happened in Wuhan. The potential upsides are few - would any doubters be silenced if the investigation found nothing? I can also believe that even if they have no reason to believe that the lab leak theory is true and their internal investigations have turned up nothing, that they're not entirely convinced there is zero chance there wasn't a lab leak. Even if they think there's only a 1% chance there was a lab leak, then the idea of an outside investigation is clearly dangerous to them. Blocking an investigation is safer.
