Many countries with non-stan names in English have -stan names in their own languages, like Hindustan.

Also, lots of Mid East or central Asia town names end with -abad (https://en.wiktionary.org/wiki/%D8%A2%D8%A8%D8%A7%D8%AF#Pers...). Interestingly, so do some large American city names, I can't remember which.
