Chinese democracy is not a lie, it is simply different from what many of us take to imply a democratic process. It is, perhaps in our perspective, a less... evolved form of democracy but casting dispersions on their form of legal government simply to be a decry them as somehow less adapted then ourselves is arrogant and ignorant.
Cuban socialism, for better or worse, saw the country through some very turbulent times and played a large role in the continued solidarity of Cuba as an independent nation. Adding democratic elections to the already demonstrated form of rule could be a very good thing for Cubans. And it was modeled on an at-least partially successful template, so the question I have is; how will a "better form of socialism" manifest itself alongside a "more democratic society"?
