The cat is out the bag. Most of the people in the world will be exposed to this virus and survive. China knows this. China also knows it's not possible to remain isolated from the virus and its effects. Even if that was possible, China's citizens would have to remain in virtual isolation until a vaccine was developed. Who knows when that will be or the knock on effects.
China went to extreme measure to lockdown and contain this. To believe the rubbish that they stopped testing is thrash. They contained it, aggressive testing, contact tracing and quarantine is what I have read from other sources they are using to keep it at bay with all new infections being from international travelers.
