Chinese are developing their skill to fight a pandemic using pretty mild Covid as a training tool

The skill includes classical control of the pandemic and pretty high tech (PCR test for many millions of people in just days, anyone?). When next Black Death will show up, as it inevitably will,  that skill might be very handy. Then the rest of the world would have a lot of cheap assets, including land, wouldn't it? Guess who would buy all the assets?
