an investment in Vietnam

You want to make an investment in Vietnam since its booming economy  but you lack critical information necessary for an intelligent  investment decision, namely, what are the laws and legal system of  Vietnam like.  How will your investment profits be taxed, how will the  state protect your resources, will the state expropriate your  investment, and is there adequate enforcement of contracts?  Law is the  foundation of private enterprise in the modern nation because if law and  its enforcement are inadequate, the risks of doing business are too  great.
