A central concept in Global International Relations (IR) is ‘global’ or ‘globality,’ which has been commonly understood as the sum total of all geo-cultural parts of the world. This understanding underpins Global IR’s efforts to make IR more geo-epistemologically representative and inclusive, but it has been criticized for its essentialism trap and geo-epistemology. While many critics problematize Global IR’s conception of globality, few pay attention to an alternative form of existence of globality, namely, its embodiment within each of the ‘geo-cultural’ parts. This article aims to engage with this form of globality by drawing on the conceptual framework of quantum holography, which sees the whole as not just comprising its parts but also being encoded within them. The implications are that if global-local relationality is holographic in nature, globalizing IR should entail not only externally expanding IR’s geo-epistemological horizon but also discovering and appreciating the globality that always already exists within each locale. Thus, this approach may help us tackle the stubborn binary of global vs. local/national in the Global IR debate and mitigate its essentialism trap and geo-epistemology. To illustrate, we apply this framework to problematize ‘Chineseness’ in the Chinese School of IR theory.
