These "news" get recycled periodically. The Canadians and Spaniards both have long histories of dealing with Castro and his cronies. I am not aware that any of the deals have yielded happy results for the foreign partners (with the Cuban government), and there's a long line of prospective investors that've gone home with their tails closely tucked under.
While capitalists will exploit most any opportunity to make money, a major consideration has to be first how they're going to make it, followed by how they're going to repatriate it. In a country controlled by the brute force of men who believe that capitalists are at best "gusanos" and at worst degenerate, immoral exploiters of "the people", I wouldn't want to be doing the risk analysis for those deals.
And even if the Castro regime experiments with the Chinese model, the temperament and culture of the remaining population is unlikely to simultaneously hold capitalist ideals while marching to the tune of the Communist Party. No doubt that the expatriate community will have some say. Just like Israel cannot accept the rights of return of Palestinian refugees and survive as a Jewish state, neither can communist Cuba and golf course investors when legitimate claims are made on property forcibly taken by the communists.
The other thing to consider is that Cuba is a rather small place with an extremely poor population. How many courses can it sustain?
It is a beautiful island, one of many in the world. Once the "forbidden fruit" attraction wears off, what will it fall back upon? Gambling? Legal prostitution? Drugs? Vice? Been there, done that; enabling the intelligentsia to overthrow the government and force a 50 year experiment in deprivation and hardship on "the people". God only exiled his immoral, rebellious, faithless chosen people, the Jews, to wander the desert for 40 year! Surely no one here is suggesting that the new land of milk and honey is replete with neo-classical golf courses?
Let's pick somewhere else.
