They have also imposed several left-wing actions, like nationalization of oil companies (and your comparison is with Norway is again without merit as Chavez nationalized several industries - including oil - without significant compensation and put his incompetent cronies to run it, which means they don't produce as much as when they were privately run)
I imagine most people in Europe would consider their political position as left of the US. That doesn't make them communist.
So the argument that you are trying to make is that a state is communist when it nationalises industries (not only one industry) and those industries are not:
Oil (Norway, Saudi arabia, UK)
Aerospace (Canada, UK)
Cement (Pakistan)
Food (Zimbabwe, Croatia)
Mining (Sweden)
The only company Venezuela has nationalized that does not fit one of these criteria is a glass producing company. To be honest if I looked hard enough, I could probably find an example of such an action in another country.
However, the definition of communist is not 'a poorly run country'.
