Modi-Xi Summit Signals Major Geopolitical Shift as Trump Tariffs Drive India Toward China Alliance

Indian Prime Minister Narendra Modi's August 2025 visit to China marked an important step in the cautious normalization of relations between Asia's two largest countries, but it did not amount to a new India-China alliance. Modi met Chinese President Xi Jinping in Tianjin on the sidelines of the Shanghai Cooperation Organisation summit, his first trip to China in seven years.

The meeting came at a particularly sensitive moment. India and China were already trying to stabilize relations after years of tension along their disputed Himalayan border, while New Delhi was simultaneously confronting a sharp deterioration in its trade relationship with Washington. President Donald Trump's administration had imposed tariffs that brought duties on many Indian imports to 50%, including an additional 25% levy tied to India's purchases of Russian oil.

Those developments gave the Tianjin meeting added geopolitical significance. Yet India's diplomacy remained more complicated than a simple shift from the United States toward China: New Delhi continued its security and economic relationships with Washington and other Quad partners even as it sought a more workable relationship with Beijing.

Why the Modi-Xi Meeting Mattered

Relations between India and China deteriorated sharply after the deadly June 2020 clash in the Galwan Valley along the disputed Line of Actual Control. Troops remained deployed in large numbers across parts of the frontier, and the confrontation affected diplomatic, investment and travel ties.

By the time Modi arrived in Tianjin, however, the two governments had already begun a gradual process of disengagement and diplomatic repair. The leaders' meeting therefore built on an existing thaw rather than creating one from scratch.

Modi and Xi emphasized the importance of managing disagreements without allowing them to define the entire bilateral relationship. The broader agenda included border stability, trade, investment, people-to-people contacts and the restoration of transport links.

That distinction matters. A warmer summit atmosphere does not erase the countries' unresolved territorial dispute, strategic competition or India's concerns about China's close relationship with Pakistan. Nor does it establish a formal strategic alliance between Beijing and New Delhi.

U.S. Tariffs Added Pressure to India's Strategic Calculations

The timing nevertheless ensured that U.S.-India trade tensions were central to international interpretations of Modi's visit. On August 6, 2025, the White House issued an executive order imposing an additional 25% tariff on many Indian imports, citing India's direct or indirect imports of Russian oil. The additional duty took effect later that month and stacked with other applicable tariffs for many products.

The measure intensified an already difficult trade dispute. It also created additional incentives for India to diversify economic relationships and reduce its vulnerability to pressure from any single major power.

That did not mean U.S. tariffs alone caused the India-China rapprochement. Diplomatic repair between Beijing and New Delhi had begun earlier, particularly after progress on border disengagement in 2024. The tariffs instead became another factor shaping India's long-standing effort to maintain strategic autonomy.

Border Stability Remained Central

The disputed border remained one of the most consequential issues separating India and China. The Tianjin talks reflected an effort to prevent renewed military confrontation while allowing cooperation in other areas to resume.

That approach should not be confused with a settlement of the territorial dispute. The Line of Actual Control remains contested, and the two governments have differing territorial claims. Progress in disengagement and confidence-building can reduce immediate risks without resolving the underlying sovereignty questions.

Economic considerations also encouraged both governments to stabilize the relationship. China remained a major source of goods and industrial inputs for India, while India's large and rapidly growing market continued to attract Chinese commercial interest. At the same time, New Delhi has sought to reduce vulnerabilities in strategically sensitive supply chains and has maintained restrictions affecting some Chinese investment and technology activity.

The SCO Summit Was Not an India-China-Russia Alliance

The Shanghai Cooperation Organisation summit brought Modi and Xi together with Russian President Vladimir Putin and leaders from across Eurasia. The gathering highlighted the growing diplomatic importance of institutions in which Western governments are not dominant.

That does not make the SCO a unified anti-Western alliance. Its members have different foreign-policy priorities and, in some cases, serious bilateral disputes. India, for example, has continued participating in the Quad alongside the United States, Japan and Australia while also remaining an SCO member and maintaining extensive ties with Russia.

This overlapping diplomacy is characteristic of India's approach to major-power competition. New Delhi has generally sought flexibility rather than exclusive alignment with either a U.S.-led or China-led bloc.

Similarly, warmer interactions among Modi, Xi and Putin did not demonstrate that the three governments had formed a common strategic front. Their interests overlap in some areas and diverge substantially in others.

What the Meeting Meant for the U.S.-India Partnership

The Tianjin meeting raised questions about whether worsening trade tensions with Washington could weaken U.S.-India cooperation. The United States has invested heavily in relations with India as part of its broader Indo-Pacific strategy, while the two countries have expanded defense, technology and diplomatic cooperation over several years.

At the same time, India has consistently resisted being treated as a formal U.S. ally or as an instrument for containing China. Its foreign policy has generally emphasized strategic autonomy and relationships with multiple competing powers.

The events after the summit demonstrated why it was premature to describe India as moving permanently into China's geopolitical camp. In February 2026, Washington announced that the additional 25% Russia-related tariff would be removed and said the reciprocal tariff on Indian goods would be lowered from 25% to 18% as part of a bilateral trade framework. The White House order removing the additional Russia-related tariff took effect for qualifying imports on February 7, 2026.

Trade negotiations nevertheless remained unfinished later in 2026. By late September, Indian officials were still pursuing an interim arrangement and a broader bilateral trade agreement with Washington. Modi and Trump also reaffirmed their commitment to the U.S.-India Comprehensive Global Strategic Partnership in a September 30 call, according to the Indian government's account reported by Reuters.

Russian Oil Remained a Complicating Factor

Russian energy purchases remained another reminder that India's foreign policy could not be reduced to a choice between Washington and Beijing. India became one of the largest buyers of discounted Russian crude after Russia's full-scale invasion of Ukraine in 2022, arguing that affordable energy was important to its economic interests.

The Trump administration explicitly linked its 2025 additional tariff to those purchases. Although the White House later said India had committed to stop directly or indirectly importing Russian oil when it removed that tariff in February 2026, subsequent market data showed that Russian crude continued flowing to Indian refiners.

By September 2026, Reuters reported that Russia remained India's largest crude supplier, even though volumes had declined from the previous month. The continuing flows illustrate the gap that can exist between diplomatic commitments, commercial decisions and the eventual implementation of policy.

Economic Opportunities Come With Significant Constraints

A more stable India-China relationship can benefit businesses in both countries. Improved transport links, easier visas, reduced border tension and clearer investment rules can lower costs and make commercial engagement easier.

But claims that the summit created a unified Asian economic market or guaranteed sweeping new access for Chinese companies go beyond the available evidence. India and China remain competitors in manufacturing, technology and regional influence, and New Delhi continues to pursue supply-chain partnerships with the United States, Japan, Europe and other economies.

The same caution applies to predictions that Indian technology standards will shift wholesale toward Chinese systems. No such broad realignment followed automatically from the Tianjin meeting.

Instead, the economic significance of the rapprochement lies in optionality. Improved relations with China can give India more diplomatic and commercial room to maneuver, just as closer ties with the United States, Europe, Japan and other partners provide alternatives to dependence on Beijing.

A Thaw, Not a New Alliance

The Modi-Xi summit was consequential because it demonstrated how far India-China relations had moved from the crisis atmosphere that followed the 2020 border clash. It also occurred while U.S. tariffs were placing unusual strain on Washington's relationship with New Delhi, increasing the geopolitical attention surrounding the meeting.

But the evidence supports describing the development as a cautious diplomatic thaw rather than a durable India-China alliance. The border dispute remained unresolved, strategic mistrust persisted, and India continued to deepen or preserve important relationships with countries concerned about China's regional power.

Later developments reinforced that picture. Washington and New Delhi moved to reduce some of their tariff dispute in 2026 and continued negotiations over trade and strategic cooperation, while India simultaneously maintained dialogue with China and commercial ties with Russia.

Rather than choosing one geopolitical camp, India continued to pursue a multi-aligned strategy: cooperating with different powers where interests overlap while preserving room to disagree with each of them.
