While I have frequently visited those three countries - including spending a lot of time working in Vietnam, and know many people who live in them, they all live in cities or tourist areas. No doubt there are Westerners living in villages, but I'd imagine it would be tougher than it currently is here. I'd also look at communication and infrastructure as well as your points: Fibre optic internet coverage. Quality of mobile network. Ease of ordering items that you want online (Lazada etc) and having them delivered to your door. This includes food items, electronic and hobby equipment, and whatever else you may need to make your life simpler/more enjoyable/bearable. Because there's no way you'll be getting them locally. General road quality, and how easy to buy and drive your own (or a family member's) car - being able to drive yourself about when and as required, or the fancy takes you, is, in my opinion, essential when living in a rural area. Nearby medical services. Anywhere to meet and talk/drink with other Westerners. Not actually an issue with me, but many seem to need it. Reliability of electricity supply, or ease of purchase and installation of a solar system. No doubt others will have additional requirements to these ones. Note I said tougher than it currently is here, as many, including myself, lived in villages here before most of these things existed upcountry. However, back then the first three in particular didn't exist anywhere. Now that they do exist, it would be tougher to move somewhere where they still don't. (Some may differ on this point and be able to live in a cave with no communication with the outside world, but not me).

And the first two are Scottish person looking for their car.
