Since the 18th National Congress of the CPC, the complex international environment of "world multi-polarization, social informationization, and cultural diversity" has bred the culture "rejection reaction" which was advocated by some Western countries, and the wrong arguments such as "China threat theory" has been occurred from time to time. To these questions, we should actively engage in in-depth cultural exchanges with foreign countries. The exchange and mutual learning of human civilizations is an important driving force for promoting the progress of human civilization and world peace and development. By seeking common ground while reserving differences, strengthening communication and understanding, and mutually absorbing the excellent achievements of various civilizations, Chinese excellent civilization should explore its modernity genes to "go global" and "welcome in" foreign excellent civilizations, to jointly build a community with a shared future for mankind. For the exchange of civilizations between China and foreign countries in the new era, we should have a profound understanding of the inherent meaning of "the beauty of each other:transcending cultural barriers through cultural exchange; the beauty of believing that others are excellent:transcending cultural conflicts through mutual learning of civilizations; beautiful together:transcending cultural superiority through coexistence of civilizations". We should vigorously highlight the era value of the new era, that is, "realistic needs:promoting the Chinese path to modernization; meaning of the topic:helping to realize the great rejuvenation of the Chinese nation; appeal of the times:promoting the construction of a community with a shared future for mankind". We should actively promote the practice approach of "strengthening cultural communication to promote the integration of civilizations, always adhering to the main force of Chinese excellent traditional culture; carrying out people to people cooperation, developing common culture to promote cultural connectivity; practicing the "Belt and Road Initiative "to build a civilized road, carrying out people to people cooperation to promote diversified exchanges, adhering to the government's leading role in broadening communication channels and handling the relationship between the central ‘top-level design’ and the local ‘trial-and-error’" in the new era. On the basis of mutual equality, openness and inclusivity, we will continuously promote cultural exchanges and mutual learning with countries around the world, purposefully and systematically deepen cultural exchanges and cooperation with other countries, promote mutual learning between Chinese and foreign civilizations through exchanges, and promote development through mutual learning. This will promote the "going out" of Chinese civilization and the "welcoming in" of world excellent civilizations, and promote deep exchange and integration of civilizations from all over the world, let the consciousness of a community with a shared future for mankind take root in various countries around the world, and build a solid public opinion and social foundation for the exchange of civilizations between China and foreign countries.
