Taiwan had something similar, found it it has to do with outdoor lighting (because many kids in both China and Taiwan stay indoors to study), and started a program to let kids play outside. Along with an early childhood intervention, myopia rates have been dropping.

One would need to control for brightness differences.

Light levels outdoors will generally be much higher. As a result, the pupillary diameter will be smaller (a higher f stop in camera terms) and the depth of field will be much deeper and allow higher spatial frequency “reading” with minimal physiological accommodation.
