We conduct this sort of research, and in fact the NIH funded gain of function research taking place at WIV. So first we could reinstate the moratorium that was lifted in 2017, and we can stop funding it elsewhere. If the ultimate conclusion is that this research is too dangerous, we can create something analogous to the Biological Weapons Convention, to which China has acceded. I see no reason China wouldn't sign and abide by such a treaty.
