US has its sanctions again Cuba for reasons they very clearly voiced for over half century - takeover of US property in Cuba after the revolution.
But to be honest, I think *every* country has the right to say "we don't trade with X because".
Since US has such a dominating position in world trade, its sanctions *are* quite severe.
But nothing prevents Cuba from buying any equipment they like from Russia or China, which both will happily provide.
