The content of this paper is mainly divided into the following four parts: First, the development of the Quadrilateral Security Dialogue is sorted out; Secondly, explore the reasons for the resumption of the Quadrilateral Security Dialogue; Third, analyze the characteristics of the new Quadrilateral Security Dialogue. Finally, this paper believes that the United States, Japan, India and Australia have formed a Quadrilateral Security Dialogue mechanism based on their respective interests, but the resumption of this mechanism is not only from the continuous cooperation of the four countries, but also from the internal contradictions of the international system. The Quadrilateral Security Dialogue mechanism is deepening and the cooperation issues are also expanding. The containment and impact of Quad on China cannot be ignored.
