Is Vietnam totalitarian

Indeed, it is very similar to The Peoples Republic of China, that is,

a totalitarian state that is unlimited constitutionally or by countervailing powers in society, such as by church, rural gentry, labor unions, or regional powers. It is not held responsible to the public by free, competitive elections, and employs its unlimited power to control most aspects of society, including the family, religion, education, and social relationships.

There are various degrees of business autonomy and the use of private property. Like fascist Italy and Germany, however, during WW2, there is powerful control by government over aspects of industry, and complete

control of free trade and currency, not unlike the United States.
