If Xi Xingping can't find a better man than himself to take over China then he will probably try a second term in office. 

He probably hasn't been successful in completely rooting out corruption in government. 

Problem is the corruption could get worse if China were to assume a more democratic form of government like in Russia. 

Compare China's super economy to the poorer economy of more democratic Russia. A bad economy in China could lead to a downward spiral of revolution and civil war. Xi is a survivor of the disastrous Cultural Revolution that resulted from a French style grass roots revolution started Mao Tse Dung himself.

President Richard Nixon was right. We will make more progress to world peace by accepting the push of China to more stability for itself and the world.

In China they simply kill any corrupt government officials, traitors to their country, that they can find. Can't do that in a democracy. Probably thousands of corrupt officials have been killed so far.
