The difference between European Germanic and Latin peoples feels exactly like this in East Asia

‌
Northern European Germanic = Northern China, Koreans, Mainland Japanese
Germanic Germans = Central China, Okinawa, Japan
French/Northern Italian Latin = Southern China, Taiwanese
Spanish, Portuguese, Southern Italian Latin = Northern Vietnamese
Comparing them, the difference seems to be right around this level
It is really hard to distinguish between the Germanic, French, and Northern Italian groups
But if you compare them to the Spanish, Portuguese, and Southern Italian groups, you can tell them apart easily
However, a small number of people in Northern Spain and Madrid are somewhat similar to the Germanic groups
Just as a small number of people in Northern Vietnam are almost identical to Northeast Asians
