No, western pressure could certainly stop the CCP, but there's no political will for it. Especially not when the west is too busy self-flagellating itself over its own real and imagined wrongdoings.
Ask a Uighur how much good "western pressure" has done for the concentration camps in Xinjiang. If we're not going to war over literal concentration camps (which is acceptable; we're in too many wars already), we're not going to war over antibiotics policy.
