1 Introduction

We discussed the need to re-examine China's foreign discourse system as it approaches the center of the world stage in the context of unprecedented changes in a century. The changing international environment requires China to have the ability to adapt to external discourse changes. It has become an important mission for China to express itself, construct international relations, and shape its identity through its own discourse system. The discourse theory under the postmodern trend provides tools to solve this problem. Foucault believed that discourse is a statement that arises in a specific historical stage and is closely related to social practice, and is an important component of social life. The discourse analysis school defines discourse from the perspective of social practice, believing that social practice includes three parts: forms of labor, identity confirmation, and presentation of the real world. Discourse is a form of social practice that forms a dialectical relationship with social practice.

Definition of China's External Discourse

Deeply explored the concept definition of "China's foreign discourse" and emphasized its close connection with the concept of "discourse". Discourse originated from linguistics and later expanded to the fields of philosophy and social sciences, involving linguistics, social psychology, and critical discourse schools. Discourse is seen as a social practice that reflects and constructs social reality and identity. Foreign discourse research has made progress in theory and practice, while domestic research focuses on the construction attribute of discourse and the construction of national identity, but mostly imitates foreign theories and lacks local innovation. Discourse research is closely related to ideology, rhetoric, linguistic philosophy, and social sciences. Critical discourse analysis is a widely applied paradigm that focuses on the relationship between discourse, power, and knowledge. China's foreign discourse is defined as the discourse mode, style and structure when China tells its own story. It is a part of the discourse system with Chinese characteristics, reflects the ideological and theoretical system and knowledge system formed by the CPC leading the people, has political characteristics, and is a reflection of confidence in the socialist road with Chinese characteristics.

The Contemporary Connotation and Manifestations of China's External Discourse

Explored the contemporary connotation and manifestation of China's foreign discourse system. The Chinese foreign discourse system has semiotic characteristics and is a representation of the theoretical system of Chinese characteristics. It answers the questions of "who are we" and "how do we express ourselves", that is, the construction and expression of Chinese national identity discourse. The discourse system is a representative of the predetermined relationship between the fixed signifier and signified, defining the social meaning of the object. The formation of China's foreign discourse system is related to its interaction with the international community, which is a competition of comprehensive factors such as economic strength, military power, political influence, and cultural attraction. Due to differences in culture, politics, history, geography, and other factors, different ethnic groups have their own unique "ways of speaking". The Chinese foreign discourse system constructs a specific social reality, provides a specific perspective for understanding society and the world, and regulates society. The discourse system is a force that constructs reality and influences society. There are two main types of Chinese foreign discourse: first, the discourse and its system about Chinese practice issued by the CPC, the government and its media; The second is the voices from the public, such as think tank experts, officials, translators, journalists, etc., telling various "stories" about China or the world. As China moves towards the center of the world stage, the international community is eager to hear China's views on international hotspots and issues. Chinese think tanks, scholars, and businessmen have also begun to step forward and voice China's opinions. China's foreign discourse needs diversified and three-dimensional content to more truthfully showcase China's reality, in order to win the trust and respect of the outside world for China.

4 Discourse Interaction Models of China's Foreign Discourse Construction

Proposed a discourse interaction model path for China's foreign discourse construction, emphasizing the maintenance of the socialist system with Chinese characteristics and national interests, while paying attention to the diversity of discourse characteristics. The specific content includes: 1) diverse discourse subjects, including non official entities such as political parties, governments, media, scholars, and think tanks; 2) The discourse content is diverse, covering topics such as politics, diplomacy, and humanistic sentiments; 3) Diversified discourse channels, using new Internet media and the international arena to convey the voice of China; 4) Diversified discourse styles, involving the construction and expression of national and ethnic identity discourse; 5) Targeting diverse international audiences for precise communication. In addition, it emphasizes the importance of discourse interaction, including the interaction between China's foreign discourse and international equivalent discourse, as well as the interaction between different international discourses under the same issue, to jointly promote discourse development and communication.

5 Conclusion

The mode of China's foreign discourse has undergone five changes in the context of the new era: subject relations, communication channels, international issues, international public opinion environment, and international audiences. China's model, economic development, comprehensive well-off society and the "the Belt and Road" initiative have enhanced China's international image. In the face of change, it is necessary to construct a dialogue discourse system that adapts to China's identity.
