Chinese Democracy

In the past China was far from democratic, but more recently trends are changing. The people of China want a word in government and they care about policy. Communism is far less popular than before. But isn't government an evolutionary thing? Over the course of history for China political strife has hotly been an issue. With many internal uprisings against government and political upheavals the Chinese have been molding their selves politically and governmentally. Will true democracy even work in China? If so how can it be achieved and what role can the U.S play in it.
