Return it to an Apple store? Apple knows who to contact.
These are the type of things that make it very hard for Apple to penetrate markets outside the US.
Some people are mentioning that if Apple is given the phone, Apple will also help (and that they'd prefer to not put that message in place as a result).

Can you explain how this is much worse than, say, Google or Samsung?
No, they will not. It is just a wish. And it makes little sense for Apple to be doing that.
If you bring a found iPhone to Apple, Apple will not tell you any information about the associated customer. They don't have any infrastructure to return it. The only thing they can and will do is take the device and recycle it.
