This chapter first retraces the origins and evolution of the community of shared future for mankind (CSFM) terminology up to its incorporation in the preamble to the Chinese Constitution, while highlighting its centrality in XI Jinping’s ‘Thought on Socialism with Chinese Characteristics for a New Era’. The chapter then examines the main tenets of the CSFM, which is portrayed as a symbol of China’s commitment to fostering a ‘new development paradigm and pursuing mutual benefit and win–win cooperation’ on a global scale, on the basis of XI Jinping’s writings. In doing this, it pays particular attention to how the CSFM builds on some of the fundamental principles of international law and how it is furthermore being fleshed out through various international legal initiatives. To better illustrate this analysis, the chapter conceptually analyzes the nine core elements of the CSFM with the visual aid of the metaphoric architectural form of a ‘paifang’. The chapter concludes by pointing to some factors weighing in favour of China’s further deepening its legalist approach to international relations as the most fitting companion to its grand strategy of ‘peaceful/development rise’.
