Your link also mentions the word is used in Thai as Farang as well.

It's also in Hindi as Firangi as well.

Sort of reminds me of an anecdote I read somewhere in a book about medieval fashion - one theory is that those curvy-toed shoes you see in late medieval artwork originated in Tang dynasty China, and the fashion took ~500 years to slowly make its way west across Eurasia.
