American Strategy and Sino-Indian Détente

Introduction

The Trump administration seeks to cement a hub-and-spokes system in which U.S. superiority is maximised through bilateral leverage, with foreign competitors as equidistant from one another as spokes-on-a-wheel. The risk is that, faced with impending U.S. pressure, erstwhile allies and partners will be forced to counterweight U.S. leverage by seeking deeper relations with the PRC. This establishes a trend of détente that is beginning to characterise the Sino-Indian relationship, as both states seek to accelerate a departure from U.S. unipolarity. Whilst bilateral border tensions and overlapping strategic ambitions will ensure that India and China remain constrained to an adversarial baseline, the recent thaw in the Sino-Indian relationship may foreclose a major shift in the containment architecture surrounding China. In failing to draw a predictable demarcation between allies and adversaries, the U.S. may be establishing the grounds for its structural displacement.

The Sino-Indian Détente

China and India have recently achieved their most significant diplomatic breakthrough since the Galwan Valley clashes in 2020. This has de-escalated the border dispute, opening the door to regular cooperation. The setting of this negotiation has been multilateral forums that offer collective leverage against U.S. dominance, but only if China and India reach some form of alignment. And although there are critical motivations for both India and China to ensure that this rapprochement does not reach a full resolution of bilateral tensions, they remain aligned on one major objective: accelerating the erosion of U.S. bilateral leverage.

The Galwan border crisis entrenched five years of fraught Sino-Indian relations. 2020 saw a major border clash between India and China around the Galwan Valley in which 20 Indian soldiers were reported killed, and China took 23 square miles of Indian territory (the number of Chinese casualties is still unknown). This was the deadliest clash along the Sino-Indian border since 1967.¹ India and China responded to this dispute by breaking off diplomatic relations, expelling journalists, and implementing stringent controls of trade and FDI.² India then declared disengagement at the border as a prerequisite for diplomacy in all other domains of the bilateral relationship.³ China maintained, as it has in the past, that both nations should take a long-term strategic view, cooperating in mutually-beneficial domains even as the border dispute remained unresolved.⁴

Multilateral forums became the core medium through which India and China negotiated these differences, culminating in a decisive breakthrough at the 2024 BRICS summit in Kazan, Russia. In the months leading up to the meeting, Xu Feihong was named China’s ambassador to India after 18 months in which the position was left vacant.⁵ India and China also held bilateral discussions on the sidelines of Shanghai Cooperation Organisation (SCO) and ASEAN summits in July to prepare for a resumption of talks. Finally, on 21 October 2024, Indian Foreign Secretary Vikram Misri announced that bilateral negotiations had yielded an agreement on patrolling routes at the border, facilitating disengagement.⁶ The timing was pertinent, coming two days before Narendra Modi and Xi Jinping’s bilateral meeting at BRICS in Russia. Both leaders could then assert significant progress in Sino-Indian relations, and BRICS itself, as membership of the bloc expanded to include Egypt, Ethiopia, Iran, and the United Arab Emirates.⁷ This demonstrates the salience of multilateral formats, and BRICS in particular, as a vehicle for Sino-Indian diplomacy. The motivation behind this seems clear, given the status of BRICS as a vanguard of the Global South, and its ability to provide an insurance mechanism against Western pressure; demonstrated by the success of the bloc in ensuring Russia’s survival in the face of U.S. and allied sanctions.⁸ For this to materialise, China and India must cooperate.

The thaw in Sino-Indian relations appeared before President Trump re-entered the White House, but recent months have revealed further progress in the bilateral, adding credence to concerns that India is now seeking to cautiously hedge its relations with the U.S. and China. In December 2024, Indian Minister of External Affairs Jaishankar announced that disengagement had been achieved “in full” along the disputed border with China.⁹ India and China then began negotiations for a resumption of direct flights between both countries,¹⁰ and China’s ambassador to India began welcoming new frontiers of cooperation in visa issuance and the relaxation of FDI controls.¹¹ The Indo-Pakistani clashes following a terrorist attack in Indian-administered Kashmir on April 22, 2025 threatened to derail progress in Sino-Indian rapprochement, especially considering the degree to which Chinese military equipment facilitated a remarkably strong posture from Pakistan.¹² Yet China seems to have deftly manoeuvred the diplomatic tight-rope. As hostilities neared boiling point on April 27, Foreign Minister Wang Yi called his Pakistani counterpart, stressing China’s resolution in combatting terrorism of all kinds and safeguarding Pakistan’s sovereignty.¹³ The next day, China announced that Indian pilgrims would be able to travel to Tibet for the first time in five years.¹⁴ China therefore sought to maintain the thaw with India, despite the hostilities; a sentiment that now appears to be reciprocated by New Delhi as Prime Minister Modi agrees to meet Xi Jinping in Tianjin during the SCO summit on August 31, 2025. Meanwhile, China is offering India shipments of rare earths, fertilisers, and tunnel boring machines.¹⁵ This represents a steady enhancement of détente between New Delhi and Beijing.

It must be repeated, however, that Sino-Indian rapprochement is likely to be deliberately limited, as both states approach cooperation from an adversarial baseline. There are still approximately 100,000 troops stationed at both sides of the Sino-Indian border,¹⁶ and India and China’s territorial claims and ambitions for the region remain intractable. Both powers have also solidified partnerships with one another’s most proximate adversaries. China has made considerable inroads in South Asia through its partnership with Pakistan through CPEC; a flagship of the Belt and Road Initiative.¹⁷ This enables Beijing to extend its influence into the Indian Ocean Region, establishing overland trade routes, logistics and supply hubs, and naval bases in Pakistan.¹⁸ India, in turn, is reliant on direct U.S. military and economic assistance to address its stark disparities vis-à-vis China. India is therefore unlikely to negotiate a comprehensive border agreement with China when it lacks leverage, and would risk alienating the U.S., whilst Beijing will be resolute in presenting itself as a reliable partner to Pakistan. This entrenches an intense rivalry between India and China that will ensure a low-ceiling to cooperation.

Yet there is a major historical precedent in Sino-Indian hedging that may clarify the contradictory nature of the current détente. Following the 1971 Bangladesh War, Pakistan’s threat to India had been reduced, China had diverted its resources and manpower to its northern border following the 1969 Sino-Soviet war, and Moscow had significantly enhanced its military and economic commitment to India as a means of encircling Beijing. It was at this point that the core objective of Indian foreign policy became détente with China and an assertion of Indian independence, as the strength of the USSR-India bilateral threatened India’s strategic objective of avoiding over-reliance on foreign powers.¹⁹ This was a welcome development for Beijing, which sought to dilute Soviet influence on its southern flank. It therefore appears that India and China are willing to work together amidst considerable bilateral tension, if only to ensure that no other state in the region becomes hegemonic.

There appears to be, therefore, a standalone tenet of Indian foreign policy that prizes independence and seeks to hedge against the presence of foreign powers in India’s backyard. This is welcome news for Beijing, which sees cooperation India as a means of undermining U.S. containment strategy. What remains to be assessed is how the Trump administration will respond to the Sino-Indian détente, and how this in turn will affect relations between New Delhi and Beijing.

The Strategy of the Trump Administration

The Trump administration is likely to unintentionally accelerate Sino-Indian cooperation. This is due to a strategic mindset of bilateral powerplays that sees multilateral organisations as redundant and attempts to dominate partners and adversaries alike. Meanwhile, the adversarial nature of the Sino-Indian bilateral will likely obscure the extent to which both nations are aligned in promoting a post-American order. In approaching the rise of multilateralism with animosity and scorn, the Trump administration will therefore neglect the extent of Sino-Indian strategic alignment, posing significant risks to U.S. foreign policy.

The first Trump administration led a combative approach to Beijing through tariffs against China’s advanced technological sectors, accelerated economic decoupling, and explicitly declaring China as a threat to the United States.²⁰ The foreign policy of the second Trump administration will be more radical, as the President seeks to establish a new international structure to cement U.S. dominance. Such bold moves have been widely noted by scholars, with one influential account envisaging a world partitioned into U.S., Chinese, and Russian spheres of influence as the core objective of Trump’s new foreign policy.²¹ It may, however, be more likely that the Trump administration seeks a greater share of the spoils, seeking a world order more akin to the U.S. hub-and-spokes system in post-WWII East Asia, in which America, as central hub, maintained independent, bilateral relations with each power – barring major adversaries – as a means of maximising adherence to U.S. strategic priorities across the board.²² The presupposition of this policy is that U.S. partners do not cooperate amongst themselves, and certainly not with America’s principal adversary. The second Trump administration lacks the idealism inherent in post-WWII American foreign policy, and has instead exhibited a willingness to deal bilaterally with powers such as China, North Korea, Russia, and Iran. This introduces a far more realist foreign policy that aims simply to maximise the U.S. bargaining position as an end in itself.

An early example of this strategy has been exhibited in the European theatre, where Trump has both championed a stronger, militarised Europe whilst seeking to repair U.S. relations with Russia. Instead of creating a Russian sphere of influence, this strategy also wants a stronger Europe to counteract Russian power, albeit while permitting independent, bilateral relations between Russia and the U.S.. Thus the powers of Europe and Russia appear as spokes in an American wheel.

Another key example of Trump’s new foreign policy, with a more direct relation to U.S.-India relations, appears through the levying of a blanket tariff system, permitting the U.S. to re-negotiate every existing trade relationship on bilateral terms. So far, the Trump administration has levied a tariff rate of 15% on key allies such as the European Union, Israel, Japan, and South Korea. While China is being targeted with a tariff rate of 30%, India is facing even harsher pressure, with a 50% tariff rate threatened to take effect on August 27, 2025.²³ India will resent this attempt by the Trump administration to crudely assert itself as the dominant player, and will likely respond through further hedging with Beijing, as Modi meets Xi in China four days after Trump’s tariffs are scheduled to commence.

Ultimately, the U.S.-India strategic partnership will continue, even as India accelerates cooperation with China, BRICS, and Global South partners as a means of shielding itself from U.S. leverage. Given the relentless economic pressure now being exerted by the Trump administration on China, Beijing will seek all means at its disposal to buffer itself from economic coercion, and utilise an atmosphere of dynamic hedging that has been precipitated by the very U.S. strategy that hopes to isolate Beijing. The question remains whether Trump has the capability to confront this multilateral network. The gamble, therefore, is that the differences between states, and the strength of the U.S. itself, are sufficient to maintain divide and rule.

Conclusion

The Trump administration believes it can create an international free-for-all in which the United States, as the most powerful state actor, will dominate the board through bilateral power politics. This is a sound strategic doctrine, provided other states and blocs do not band together. Developments in Sino-Indian relations therefore pose serious questions as to the validity of U.S. strategic assumptions.

Nations that once viewed China’s irredentist tilt under Xi Jinping as a top strategic challenge are now confronted by the prospect of U.S. confrontation in the immediate future. This leads to a re-evaluation of risk, wherein the U.S. becomes the most proximate concern, necessitating closer relations with China. Although relations between India and China remain adversarial, and will remain so in the long-term, their cooperation is founded on combatting precisely the very strategy that the Trump administration is using to cement them as two separate units. In pursuing his strategy of driving wedges, and splintering multilateral institutions, the U.S. disarms itself of the very tools it needs to contain China’s military ambitions and establish a stable order.
