why do countries such as South Korea and China have latin numbers and letters on their license plates when their language doesn’t use them?

Question

Edit: Latin letters and numbers might not be the right word. I meant letters such as AaBbCc and numbers such as 123.

Answer 1

The numerals we use are Arabic in origin (not Latin). The reason they use them is that they are universally understood. I lived in Korea for a decade and they use Arabic numerals everywhere they write numbers – not just on license plates.
