According to Humberto Calderon Berti and Jose Toro Hardy, more than 100,000 barrels of crude oil are being shipped every day to Cuba from Venezuela.
In exchange, Cuba was to provide thousands of doctors, nurses and healthcare services.
But the experts argue that the healthcare services have failed to meet expectations, while the subsidised oil from Venezuela has helped the Castro regime remain afloat economically.
In fact, it seems that Castro now owes Venezuela the equivalent of over $US2 billion.
And the chances of this money ever being repaid are zilch.
Which raises two pertinent questions: how do Cubans feel about becoming an economic colony of the Venezuelans? And what is in this seemingly lopsided deal for Chavez?
