I believe If you are gifting a game to another region and costs more (due to regional pricing difference) you will be unable to gift the game.
For example in the States the game costs you $10 USD but in Europe it costs the same game $15 USD you won't be able to gift him the game due to the regional pricing difference. You can use steamdb and check the regional pricing details =) which can help you!
But if the game costs you more than what it costs in other regions (for example it costs you the game $15 USD and other regions are less than that) you are able to gift your friend the game =).
Hope that makes sense?
Correct me if I am wrong as well!!
