Is there any requirement that airports have reasonably distinct names from each other?

I've known about SYD versus YQY for a while, but I've just read that there's two airports mentioning Genghis Khan: ULN in Mongolia and NZL in Inner Mongolia in the PRC.


There's no requirement for names. Location codes can't be the same though.
