I have 400 Georgian Lari In UAE (Dubai & sharjah). where I could exchange it for AED dihrams or any other currency?
Your problem here is that the Georgian Lari is a closed currency. As a result, you aren't meant to legally be able to buy or sell the currency outside of the country, as by law, the currency itself isn't meant to leave the country.
A representative from the Royal Bank of Scotland confirms this in another forum.
