This absolutely shouldn't be China vs. USA, and it's deeply unfortunate that the Trump administration's early, characteristically unsupported rhetoric made it so. The WIV's safety was probably below American standards, but probably closer than a wet market is to American agricultural standards. So it's ridiculous to think a lab vs. natural origin makes it "more China's fault". If the CCP is currently covering up a lab accident, then they're probably quite unhappy that they've been "forced" to do so, and wishing in retrospect they'd instead decided a year ago to publicly blame the rogue, American-funded researcher.
Long before the pandemic, this was an obscure academic debate, between virologists who wanted to perform certain risky experiments and others who thought they presented an unacceptable risk:

With the possibility (absolutely not proven; but not disproven either) that such an experiment has just killed 2.9M people, that debate takes on a terrible new significance.
