<p dir="ltr">This article examines the parallel yet divergent histories of Indiaʼs and Chinaʼs Antarctic programmes, exploring their geopolitical, scientific, and cultural dimensions. Both nations, initially excluded from the Western-dominated Antarctic Treaty System (ATS), joined in the 1980s, marking a shift in their approach to the southern polar region. India, driven by post-colonial solidarity and environmental concerns, has focused on scientific research and conservation, while China has expanded its activities to include resource extraction and satellite surveillance, aligning with Russia to influence ATS policies. Both countries have leveraged their Antarctic presence to reinforce civilisational narratives—Indiaʼs Akhand Bharat and Chinaʼs tian xia—extending their cultural and geopolitical spheres. This article highlights their shared ambivalence towards ATS governance, their evolving strategies, and the role of Antarctica in their broader worldmaking projects. It argues that understanding these intertwined histories is crucial for addressing the conceptual clash between Global North-led environmental restrictions and Global South approaches to common resources, with implications for global climate and environmental governance.</p>
