“RenleiMingyunGongtongti” is the core concept and a vital component of the discourse system of major-country diplomacy with Chinese characteristics. Its translation quality can have a crucial impact on the cross-cultural communication of China’s foreign policy and the construction of its speech rights on the international stage. Taking “a community with a shared future for humanity” as an example, this paper focuses on the translation of this phrase in 30 languages used by countries along the Belt and Road Initiative. It intends to conduct a comprehensive research on the multilingual and demassified “translation and communication” of the core discourse of major-country diplomacy with Chinese characteristics from the perspective of interdisciplinary studies such as international relations, communication, linguistics and translation studies and put forward the “Demassified Translation” strategy based on the framework of “Political Equivalence”.
