Don't see much (anything?) posted from this country so here are a couple of quick snapshots from the Mergui Archipelago in that region.
Great scenery, 800+ islands, mostly uninhabited and towering limestone cliffs with jungle.
Entered via a sea border so can't really say about airports. I flow solely in the Mergui Archipelago so not over any towns or cities so best to check. We had a government minder living with us all week who had no issue with me using the drone but I'd strongly suggest asking a nearby official before flying just in case.
