Abstract: Entering the new era, in the face of major changes unseen in a century and the overall strategy of the great rejuvenation of the Chinese nation, General Secretary Xi Jinping has emphasized on many important occasions that China should vigorously advocate peace, development, equity, justice, democracy and freedom, which are the common values of all mankind. The report to the 20th National Congress of the Communist Party of China further calls upon all countries to hold dear humanity's common values and jointly address various global challenges. As important common values of all mankind, the concepts of freedom and democracy, which integrate the Western concepts, Chinese culture and the connotations of the times, are the philosophical foundation of the practice of majorcountry diplomacy with Chinese characteristics. The democratization of international relations that centers on the ideas of sovereign equality, rationalization and fairness is a way to realize the common values of all mankind. Opposing all forms of hegemony, building a solid social foundation, and enhancing diplomatic practice in various fields are practical measures to build a new form of human civilization.

Key words: major-country diplomacy with Chinese characteristics, democracy, freedom, democratization of international relations, common values of all mankind
