Analysis of President Xi’s Speech at the Extraordinary G20 Leaders’ Summit in light of Systemic Functional Grammar

Politics is a genre of language, and language is the manifestation of politics (Mazrui, 2008). Political discourse not only plays an important role in the process of national external communication but also conveys certain ideology and political intentions. Based on interpersonal function in Systemic Functional Grammar and using President Xi's speech at the Extraordinary G20 Leaders' Summit as the original data, this paper analyzes and explores how this speech can achieve discourse function through personal pronouns, mood, and modality. In addition, this paper reveals how various linguistic resources are used to realize interpersonal meaning in political discourse.
