The rhetorical “presence”of the diplomatic sentence pattern with Chinese characteristics is a unique rhetorical mode of diplomatic discourse. This paper integrates Cognitive Linguistics theories with New Rhetoric theories to explore the effect of rhetorical “presence”of the diplomatic sentence pattern with Chinese characteristics and its construal mechanism. The major findings are as follows:The diplomatic sentence pattern with Chinese characteristics achieves the effect of “presence”of diplomatic discourse through the “quantitative foregrounding”rhetorical strategy. Its rhetorical construal mechanism is that the discourse producer can promote the rhetorical “presence”by using antithetical or juxtaposed sentence patterns. The antithetical sentence is characterized by the pair mapping of the same form and the echo of the content, while the juxtaposed sentence is characterized by the repeated scanning of forms and the progressive progression of contents. Both can highlight “one world under heaven”,“peaceful development”, “win-win cooperation ” and other diplomatic philosophies containing Chinese characteristics to enhance the transmission and identification of China‘s diplomatic stance. The study of cognitive rhetoric of the diplomatic sentence pattern with Chinese characteristics contributes to the construction of the diplomatic discourse system of major country with Chinese characteristics in the new era and China’s image of major country.
