Last time I looked up the state of coronavirus origin research, the article I read said that China had stopped cooperating with outside researchers due to how the virus had become politicized, and that a lot of valuable time had been lost. It said that there was a pretty good chance that the origin was never going to be found at this point, and that even if could be, it would take at least a few years.
With the above in mind, I'm surprised an article like this even exists so soon, but having read the content of it, I think I understand why. When it comes to pandemic origin research, scientists don't just want to know where people first started getting infected since that's relatively easy, but where the virus itself came from. If the virus entered the market through an imported animal, scientists want to know from which region of China that animal came from, ideally the name of the town where that animal was first captured. If the virus entered the market through a lab leak, then scientists want to know from where that lab had collected the sample.
Generally, this is done by going out into the wild and comparing the genomes of the coronaviruses present in those animals with the one of our strain of interest. If we find a sufficiently similar match then we have our answer. As you can imagine, this takes a lot of time. Especially since China is so vast.
This article isn't interested in that though, all it wants to do is to shut down the lab leak conspiracy theory. Calling it pandemic origin research is an insult that hides the fact that China killed off any possibility of real pandemic origin research being done.
