The Rise of China has made the Taiwan question more complicated than ever within international security. Previous research has often analyzed it through Western frameworks of power, state interests, and security, but rarely from within China’s own philosophical framework. At the same time, the absence of moral and civilizational interpretation, as a result, leaves the CCP’s Taiwan discourse only partially understood. This thesis applies Thematic Analysis to 48 official speeches in the People’s Daily delivered under Xi Jinping’s leadership, covering the period from 2013–2025. It identifies six dominant themes that trace China’s rhetorical evolution from defensive sovereignty to moral legitimacy. This shift leaves just a little room for compromise. Guided by the PRC’s Global International Relations theory, particularly Relational Theory, Moral Realism, and the Tianxia System - a traditional Chinese concept of world order, the study argues that the CCP presents the unification of Taiwan not only as a moral duty but also as part of a broader civilizational vision for restoring harmony in the changing modern world order. What stands out most clearly is the paradox of the Chinese Tianxia vision. A view that shows an aspiration toward harmony, yet one that is constantly negotiated through power politics and the ongoing pursuit of legitimacy as a modern iteration of the Mandate of Heaven.
