State enterprises --- I guess command economies are better able to apply sanctions than market economies because they have a deeper control on the means of productions and the actors involved. For example, enterprises in key industries are often run by the State and these are the ones that do business with the outside world. So, any export restriction or investment withdrawal can be executed more easily, as long as it has the enough political support from the ruling elite.
