Honestly its rude to be invited by a country to meet their president who decided to respond to your criticisms of their administration only to not show up and go meet the opposition.
Being invided and then no showing shows complete disregard to basic diplomatic Etiquette since it was a mission to show solidarity against the embargo
Bonus socdems being cringe part 4.5: about another member that didnt show up to the presidential meeting
If I got to visit the actual fucking leader of Cuba then I would be there early and probably listen for the vast majority of the time; berating or asking sectarian questions would be almost at the bottom of my list. They're the people who have succeeded while we have failed, we have to listen to them
Goes to show how hilariously distant the Cuban government is from the cartoon of a totalitarian cartel regime US media paints them as that Canel even bothered to hear them out.
