India's Taiwan Calculation: The Swing State That Watches Without Committing
India fought a border war with China in 1962, has had active military clashes with Chinese forces along the Line of Actual Control as recently as 2020, and maintains a territorial dispute with China that has never been formally resolved. It is a member of the Quad alongside the United States, Japan, and Australia. It has been deepening security cooperation with the United States, Japan, and Taiwan itself through informal technical and commercial channels. And yet India’s position on the Taiwan Strait remains studied ambiguity: it recognizes the People’s Republic of China, does not formally recognize Taiwan, and has consistently declined to make explicit statements about what it would do in a Taiwan contingency.
The ambiguity is rational and not simply inconsistent. India’s strategic situation is more complex than its Quad membership implies. It shares a disputed Himalayan border with China that requires ongoing military management. It maintains a relationship with Russia — its primary military supplier for decades — that it has been diversifying but cannot abandon overnight. It has a domestic political tradition of strategic autonomy that predates independence and that makes formal alliance commitments politically difficult regardless of which direction they point. And it has learned from its own history that explicit security commitments to distant theaters are not reliably honored by major powers when the political costs of honoring them are high.
The China threat, however, is the most powerful driver of India’s implicit alignment with the American position on the western Pacific. A China that has subjugated Taiwan and consolidated control over the South China Sea would be a China with dramatically improved strategic depth, a demonstrated ability to coerce neighbors at will, and a regional posture that would translate directly into increased pressure on India’s own territorial disputes and maritime interests. Indian strategic planners understand that the Taiwan question is not geographically remote from Indian interests. A Chinese victory in the strait reshapes the entire Indo-Pacific balance in ways that reduce India’s regional standing and increase its security burden.
The practical contribution that India could make to Taiwan’s defense — or more broadly to a coalition response to Chinese aggression in the strait — is indirect but real. India’s geographic position in the Indian Ocean gives it the ability to complicate Chinese maritime operations in the western Indian Ocean, threaten Chinese energy supply lines from the Gulf (which run through waters where Indian maritime forces have increasing presence), and deny China the strategic rear that a subdued Indian Ocean would provide. None of this requires India to declare a position on Taiwan. It requires India to maintain and develop the maritime and air capabilities that would give it leverage over Chinese strategic calculations about the costs of military adventurism.
The Taiwan semiconductor relationship adds a dimension to Indian calculations that is rarely discussed. Taiwan is the world’s most important chip producer, and India is embarked on an ambitious semiconductor self-sufficiency program that depends in part on knowledge transfer, equipment, and investment from Taiwanese companies. TSMC has declined to build fabs in India — the ecosystem requirements are not yet present — but Taiwanese companies with less leading-edge process requirements have invested. A Taiwan absorbed into China under hostile conditions would end this relationship and would put Indian technology development ambitions at the mercy of a geopolitical adversary.
India will not fight for Taiwan. It will not say so publicly. What it will do is continue developing capabilities and relationships that give it options in the Indo-Pacific competition, maintain enough strategic distance from Beijing to preserve those options, and watch the Taiwan situation with the attention of a country that knows the outcome will affect it regardless of whether it is at the table when the outcome is decided.
Strategic autonomy is India’s policy. In the Taiwan context, it is also its contribution to deterrence — by keeping China uncertain about what India might do if the strait is tested.
