Most national averages are highly regional.
In China, for example, there are ethnic tribes with higher percentages.
So are in Japan (the Ainu).
This is why, in the name of keeping it real, it is sometimes better to have honest estimates rather than opinionated conclusions.
Here is more:
RH negative blood, compared with the common A, B and O types, is a variety highly unusual in China. With only 0.1% to 0.3% of the population having this blood running through their veins, it is therefore referred to as “panda blood.” Rare as the blood type is, people with RH negative blood must not be ignored. A dozen thousand women with this blood type get pregnant in China every year. Local RH negative blood banks are often in urgent need of supplies.
