It's a pretty elastic word these days, especially given China. And of course they do want overseas trade. The US embargo of using the power of the state to make it as difficult as possible for even non-US companies to trade with Cuba is hardly a pro-freedom one.

So far as I can tell it's this way because 95% of the US doesn't care one way or the other but there are Cuban exiles in Florida who care a lot about punishing Castro, and they're good at voting.

That's a proof their system was a lie. Che Guevara gave an speech about how Cuba would thrive without global trading, without private property. Well, the results speak for themselves. No communist regime could survive with its own production. It seems i triggered some communism fans.
