China's Emergence in South Asia: A Strategic Stability Paradox of Economic, Military, and Nuclear Engagement

Abstract

This paper examines the emergence of China as a strategic actor in South Asia between 2013 and 2026, investigating whether its economic, military, and nuclear engagement in the region functions as a stabilizing or a destabilizing force. Existing scholarship has tended to analyze China's economic initiatives — principally the Belt and Road Initiative (BRI) and the China–Pakistan Economic Corridor (CPEC) — and its military and nuclear cooperation with Pakistan as separate and largely unconnected domains, leaving unresolved the question of how these dimensions interact to shape regional strategic stability. Employing a qualitative research design grounded in directed content analysis of secondary documentary evidence, the study applies an integrated theoretical framework combining Realist and Constructivist perspectives, extended through Snyder's stability-instability paradox to a trilateral China–India–Pakistan context. The findings demonstrate that China's engagement in South Asia cannot be reduced to a binary characterization of stabilizer or destabilizer, but instead produces what this study terms a hybrid paradox, in which the same instruments of economic investment, military cooperation, and nuclear assistance simultaneously generate stabilizing and destabilizing effects. China's economic engagement delivers genuine infrastructure development while generating structural debt dependency; its military cooperation strengthens Pakistani deterrence while intensifying India's threat perception; and its nuclear assistance sustains macro-level deterrence stability while enabling the operationalization of Pakistan's Full Spectrum Deterrence posture, thereby lowering the nuclear-use threshold. The paper concludes that regional responses to China's engagement diverge not through misperception but through each actor's distinct structural position within the regional security hierarchy, and it offers actor-differentiated policy recommendations for Pakistan, India, China, smaller South Asian states, regional organizations, and the international community.
