On [October 19, China] posted positive economic growth for the second quarter in a row, underlining how speedily the world’s second-largest economy has recovered. That comes in the wake of an apparently successful experiment with allowing mass domestic travel, as millions of people criss-crossed China for the Golden Week national holiday.

China’s success in controlling the coronavirus is not so much a product of those early control measures — though these have been utilized effectively to halt regional flare-ups — but how the country handles things after people are allowed to move around again.

In particular, China’s ability to track and trace cases across the country whenever there is the suggestion of a new cluster of infections has enabled the government to respond quickly and bring local epidemics under control.

This has included a sophisticated color-sorted “health code” system to track people’s movements. A clear (green) bill of health and corresponding QR code is required to enter many businesses.
