Surely Cubans want to export their sugar, tobacco, genetically engineered medicine, etc. to the USA & elsewhere. They need forex earned through exports to finance imports.
Even Jose Bove, a militant left-wing sheep farmer against "corporate globalization," wants to export Roquefort cheese. His trashing of McDonald's was in reaction to the punitive 100 percent tariff on some French products -- among them Roquefort cheese -- that the US government placed in retaliation against a French ban of unlabeled hormone-treated American beef.
The question is balance. No nation can afford to rely primarily on exports of such neocolonial products as minerals & agricultural produce to develop their productive forces.
