It seems NO.

In Soviet Union considerable part was in cooperation. And more in Stalin era then later.

Citing Russian wikipedia:

> By the end of the 1950s, there were more than 114 thousand workshops and other industrial enterprises in its system, where 1.8 million people worked. They produced 5.9 % of the gross industrial output, for example, up to 40 % of all furniture, up to 70 % of all metal utensils, more than a third of upper knitwear, almost all children's toys. The system of commercial cooperation included 100 design bureaus, 22 experimental laboratories and two research institutes.

China is capitalism all the way now.

IDK about North Korea but they don't seems like a "communist country" for me.
