A Comparative Study of the 1962 and 2020 Sino-Indian Military Conflicts through the Lens of Sun Tzu's The Art of War

The Sino-Indian border dispute is a key variable shaping the geopolitical landscape of Asia. This paper aims to explore, through a comparative analysis of the 1962 Sino-Indian border war and the 2020 Galwan Valley conflict, how classical strategic thought from Sun Tzu's *The Art of War* provides an analytical framework for understanding modern limited warfare and gray-zone competition in different temporal and spatial contexts. This paper employs a qualitative comparative case study method, selecting core concepts from *The Art of War* such as "strategic planning," "preferring non-military means," "the situation," "deception and asymmetry," and "knowing the enemy and knowing yourself" (intelligence and cognition) to systematically analyze the strategic logic, escalation dynamics, and conflict management models of the two conflicts. The study finds that the 1962 war embodies a typical limited warfare model that uses "military aggression" to achieve political objectives, and its characteristics of "swift victory" and "proactive withdrawal" highly align with Sun Tzu's caution regarding the costs of war. In contrast, the 2020 conflict demonstrated a modern translation of the idea of "subduing the enemy without fighting" into "gray zone competition" within the context of nuclear deterrence, with the conflict itself becoming a long-term process of shaping "momentum." The study also points out that misjudgment of "knowing the enemy" was a key catalyst for escalation in both conflicts. This paper concludes that *The Art of War* not only provides a historical perspective for understanding Chinese strategic culture, but its inherent cost-benefit analysis, emphasis on information asymmetry, and focus on non-military means make it an effective theoretical tool for analyzing strategic competition among major powers.
