In Vietnam, little has changed ...

... despite doi moi, it's still basically the same repressive communist police state - just like every other communist state that has ever existed.

When I lived there, it is a fact that our faxes and telexes (internet operations were in their infancy then), and probably our telephone calls, were all monitored and visitors to the homes of foreigners were likewise tabulated closely. Vietnamese citizens were subjected to far more obtrusive controls. Clearly, little has changed at root.
