This is just a speculation. Not a statement.
Top covid scientists in PRC and CCP have mentioned the gradual opening of borders at 85% vaccination rate. And about gradually living with virus in society. Aforementioned are stated in their State Controlled Media, not Financial Times. Why would the Chinese release such statements repeatedly about eventually opening borders in multiple sources? If by then the whole rest of the world has developed some sort of immunity and she is still closed up to the world, who will be the laughing stock in the end?
