Am I to believe that China was working on weaponizing a virus without also concurrently researching a cure/vaccine?
Virus provenance is important. It’s not a blame game. If it escapes from a lab they owe the world every piece of research they have on it but we’ll never get there if everyone says “hey hey let’s not play the blame game here”
No, you are not to believe that, there is no evidence for it. But there is plenty of evidence that nation states in general have done research on the weaponizing of disease.
Note that that doesn't rule out that it wasn't the case, but it is to the best of my knowledge not something that we have even a shred of direct evidence for.
