First let me tell you that I speak from two years of experience on the ground in Vietnam....80% of it outside of Saigon...in the real Vn with real government officials, police chiefs, business peeps of all types and sizes. If you spend all you time in Saigon and think you kow VN then I suggest you reconsider your perspective. I should point out that I have been living abroad and have operated a business as a foreigner in a foreign country for years before coming to Vietnam. My ex was Vietnam born Vietnamese back in my home country so I have more than most of you in terms of an introduction into Vietnam culture. She warmed many years ago that the VN counld not be trusted....
If your entire expectation of VN is to enjoy an Asian country on the cheap and it's fun attributes then you can be a happy camper.
If though, and to the point of this post, you get the inspiration to 'make a life in vietnam as a foreigner' and you think that you can enter into investment and business ventures like any reasonable country in the modern world....then you should take heed of my warning.
Don't do it. You stand an 80% chance of getting reamed ....and I don't claim to be IMHO but in my learned opinion. I've personally met over 60 foreigners who have been through the ringer..some going back twenty years...and the stories are just endless of their friends, countrymen or foreginers of all kinds that have felt the weight lifted from heir wallets and bank accounts and egos. The deck is so stacked that you stand little chance of succeeding and no amount of 'American or British or French or ...whatever...stiff upper lip' will make a difference. The entire VN investment horizon is a mirage...a mirage of smiling friendly Vietnamese who will not stab you in the back with a physical knife... but instead will slice your wallet and good intentions into a bled carcass all the time say 'so sorry you have bad luck...cannot help you'.
There is nothing, statistically, fair about the playing field for foreigners trying to do biz in VN. It's rigged to fleece you...just take my advice and move on to another country.
You may hear of 'government registered contracts' or 'guaranteed compliance' or other terms they local government officials sell you to invest in their projects. I speak from personal experience...it means nothing because when the deal goes against you then you wil get the quick push out of town by the local police and lawyers will get the word not to take you on as a client in that area....and surprise the local judicial process always rules in the favor of the local who reamed you.
There is NO RULE OF LAW nor even in CONTRACT LAW...you are the rich foreigner and they are the poor VN and that is the only thing they care about...you must be fleeced....
