The General Secretary's congratulatory letter fully reflects a high level of consciousness in preserving one's own cultural traditions and promoting mutual learning among civilizations, expresses earnest expectations for strengthening classical studies, and provides scientific guidance for continuing the historical context, enhancing dialogue between civilizations, and promoting the development and progress of human civilization.

Classical civilizations shine like a galaxy, serving as the pinnacle and eternal beacon of human civilization, continuously nourishing and inspiring future generations. Over two thousand years ago, the civilizations of China and Greece, located at opposite ends of the Eurasian continent, illuminated each other, making foundational contributions to the evolution of human civilization. This conference, jointly organized by China and Greece, is themed "Classical Civilizations and the Modern World." It aims to explore the origins of human thought, summarize historical wisdom, and uncover the traditions of human civilization from the perspective of classical studies, thereby strengthening the academic foundation for cultural exchange and mutual learning, providing wisdom for addressing modern world issues, and injecting intellectual momentum for the progress of human development.

A history of human development is also a history of the coexistence and progress of diverse civilizations. There are multiple countries and regions, numerous ethnic groups, and various religions in the world. Diversity brings about exchanges, exchanges foster integration, and integration leads to progress. The exchange and mutual learning of civilizations are significant driving forces for the advancement of human civilization and the peaceful development of the world.

This series of important concepts, crucial judgments, and major initiatives, from the perspective of the overall interests of all humanity, examines the relationships between nations, understands the recognition of value connotations in different civilizations with a broad mind, and demonstrates the noble spirit of "the world belongs to all" and the far-sighted wisdom of "beauty for all," pointing out the developmental logic and direction of human civilization. These ideas have increasingly gained traction in the international community, injecting profound and lasting cultural strength to propel human civilization along the correct path.

In today's world, the great transformation unseen in a century is accelerating, and the development of human society is marked by twists and turns. The two orientations of unity and division are intensifying each other, challenges and opportunities are intertwined, and there is a high degree of instability and uncertainty. To resolve the prominent contradictions and issues facing humanity, it is necessary to rely on material means to overcome difficulties, as well as spiritual strength to foster sincerity and integrity. In an era where the destinies of nations are closely intertwined, the inclusive coexistence and mutual learning of different civilizations are increasingly evident in their role in promoting the modernization of human society, bringing the essence of all civilizations to benefit the present and humanity.

Culture is like water, silently permeating; civilization is like a tide, resounding and expansive. The 20th Plenary Session of the 20th Central Committee of the Party, from the strategic height of building a strong nation and the rejuvenation of the nation, focuses on building a socialist cultural power, proposes significant tasks for deepening the reform of the cultural system and mechanisms, and emphasizes the establishment of a global civilization initiative implementation mechanism. On the new journey, we must uphold the stance of Chinese culture, continuously strengthen the study of classical scholarship, refine and showcase the spiritual symbols and cultural essence of Chinese civilization, and explain and promote to the world more excellent cultures that feature Chinese characteristics, embody the Chinese spirit, and contain Chinese wisdom; we must promote the construction of bilateral and multilateral cooperation mechanisms for cultural exchanges, implement the global dissemination project of Chinese civilization, actively participate in world civilization dialogues, expand international cultural and humanistic exchanges and cooperation, better promote Chinese culture to go global, allowing the driving force of development to flow unceasingly and the light of civilization to shine brilliantly.
