All the credible experts say that this virus is natural and that it may have jumped to humans years ago, and also that people in the relevant rural areas of China have antibodies for similar virii. And then there's also SARS, MERS, Ebola, etc.
There is a reason experts have been raising the alert for years about this: what has happened was inevitable.
But of course laying the blame at the feet of an "hostile" government can buy you political mileage, not least during an election year or when you're coming under criticism.

Basically a percentage of the people who live in areas close to large populations of bats in Southern China have antibodies for SARS/Covid-like bat viruses, suggesting natural, ongoing contacts.
That's probably how SARS, MERS, Covid-19 all started.
