Large landowner (ex aristocrat) or government, what difference does it make? The land is forever not yours.
You lease it for 50 years, but in the end you can sell the actual property to a citizen or sell it to a non-citizen who will get a 50 year lease.
Vietnam still is a communist country in that respect.
The government still owns all the land and is legally leasing it to its citizens and foreigners. In reality, now that Vietnam is increasingly open to the world economy the government has to treat property rights better or else it'll scare foreign investment away.
The lack of private property rights and the Vietnam's Communist Party stranglehold on the economy with their state owned enterprises is a huge drag on productivity and innovation.
Fortunately, it seems like things are improving.
Hell even Singapore limits property ownership of foreigners.
