How did the chinese communist revolution differ from the russian revolutions?

Russia realized that a balance needed to be maintained despite its opposition to democracy.  China during the early days wanted to pursue a more aggressive policy against democracy.  Later on, this led to a split between the Russians and the Chinese.  Ironically, to protect itself the Chinese opened relations with the United States when Nixon went to China.  Later on, China though communist started economic reforms that were capitalists in nature.  The USSR later collapse and Russia became a democratic country and adopted capitalist reforms.
