WHO is UN body charged for medical activity. So case of Wuhan lab is done and over by UN.The Ukrainian labs, maybe. It will depend on the evidence collected by Russia.
But not other bio labs, in particular those in the US. If China did bring it up, in a counter measure, the US could demand UN inspection on the Wuhan Virology Institute. Not that China is hiding anything, it's about dignity and sovereignty. Neither side would cave in. Such motion in the UN would not go anywhere.
China allowed the visit by WHO. That's it.
