The Chinese system is new, Xi said, also because it pools ideas and suggestions through institutional, procedural, and standardized arrangements and develops a scientific and democratic decision making mechanism.

It steers away from another weakness of the old-fashioned party system, in which decision making and governance, confined by interests of different political parties, classes, regions and groups, tears the society apart, he said.

Fitting China's reality and fine traditional culture, it is "a great contribution to political civilization of humanity," he said.

Xi said upholding the CPC leadership was not meant to do away with democracy.

Instead, it aims to create a form of democracy that is broader and more effective, he said.
