If you are so keen on Laos then I suggest you come over for a month and look around and see for yourself.
As for doing any kind of business there you must be there 24/7 to keep an eye on things.
Don't even bother looking at investments online as they are usually a rip off.
Sorry to be so blunt but it is very easy to look at things through rose colored glasses and then the reality is that it is not always as you would expect it to be.
