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

Some countries like India use ARABIC (1234567890) as there are multiple languages spoken in the nation and Arabic Numerals are understood by all.

Hence Indian number plates use them.

Eg: A number plate ‘MH 01 AA 1234’ would have MH representing the state (Maharashtra), 01 representing the district, ‘AA’ representing the current series of plates and the 4 digit letter being unique to the plate.
