The policy in China is 1-2 years behind. Everyone else has realized that with Omicron a zero Covid policy is no longer feasible (and, where vaccination rates are high, not needed either), but that hasn't yet gotten through to Xi (or it has, but he thinks reversing the policy will somehow cause him to "lose face").

Not just policy, but immunity. Barring mass covid parties, it'll take China 1-2 years to get immunity on par with the rest of the world.
