Who was the leader of Vietnam who , in the aftermath of the war , ordered the government to embark on a mass campaign of collectivization of farms and factories ?
The cooperatives were divided into groups , such as " Associations of Land Cultivation " ( " Zrzeszenia Uprawy Ziemi " , " ZUZ " ) , which kept private ownership of tools and machines , and " Farmer ’s Cooperative Teams " ( " Rolnicze Zespoły Spółdzielcze " , " RZS " ) , in which both land and machines were collective .
