You're the one making assumptions I'm afraid.
We don't know where Covid-19 came from. That is the outcome. It quite well could have come from China. We have no idea. What we do know is that it didn't spread globally from a wet market in Wuhan that happens to be near a virology research centre. Because that idea hangs entirely on it appearing there first in December.
Covid-19 could have started in China. Or Italy. Or anywhere. We don't know, and as a species we seem to be very reluctant to find out - we've just accepted bat soup or bioterrorism and just moved on. Meaning that we've learned absolutely nothing to prevent it happening again.
