To refute him, Mr Hu Dehua cited Russian Communist Party leader Gennady Zyuganov's view that the Soviet Union collapsed because the CPSU had monopolised resources, political power and truth.
"If this was the case, then there was nothing to regret if the Soviet Union or the CPSU collapsed," he said.
Mr Hu Dehua then hinted that Mr Xi had misread the reason for the collapse of the CPSU. Mr Hu cited a CCP document of July 14, 1964, entitled On Khrushchov's Phoney Communism And Its Historical Lessons for the World, saying that there emerged in the Soviet Union a privileged class represented by the CPSU.
"The members of this pivileged stratum have converted the function of serving the masses into the privilege of dominating them. They are abusing their powers over the means of production and of livelihood for the private benefit of their small clique," the document said.
"The members of this privileged stratum appropriate the fruits of the Soviet people's labour and pocket incomes that are dozens or even a hundred times those of the average Soviet worker and peasant.
"They not only secure high incomes in the form of high salaries, high awards, high royalties and a great variety of personal subsidies, but also use their privileged position to appropriate public property by graft and bribery. Completely divorced from the working people of the Soviet Union, they live the parasitical and decadent life of the bourgeoisie," said the document.
Mr Hu Dehua pointed out that this was the real reason for the collapse of the Soviet Union.
