Delhi BRICS Summit: Iran War Reshapes Ties, Exposes Bloc’s Deep Divides

Shared Rhetoric, Fragile Unity

As leaders of the expanded BRICS grouping gathered in Delhi for their 2026 summit, the outward message was unmistakable: the existing global order, dominated by Western institutions and norms, is failing the developing world and must be overhauled. The host, India, carefully choreographed a narrative of collective purpose, with speeches denouncing unilateral sanctions, economic coercion, and what many member states see as an unfair international system.

Yet behind the scenes, the mood was far more complex. The ongoing war in Iran has not only overshadowed the formal agenda but has also ripped open fissures that the bloc has long tried to manage through vague communiqués. Rather than catalyzing a unified BRICS foreign policy, the conflict has amplified divergent national interests and exposed the fundamental weakness of the grouping: it is far easier to agree on what you oppose than on what you want to build.

The Iran War: A Litmus Test for BRICS Cohesion

The Iran war has reshaped diplomatic ties among BRICS members in ways that few had anticipated. While all publicly share a deep skepticism of Western military intervention and sanctions, their practical responses to the crisis have veered in markedly different directions. Some members have moved closer to Tehran, deepening energy relationships and offering diplomatic cover. Others have quietly signaled to Washington and Brussels that their core alignments remain unchanged, hedging against the risk of secondary sanctions or a broader regional spillover.

This divergence has made a mockery of the idea that BRICS could function as a cohesive geopolitical counterweight. The war has forced every member to take positions, and those positions are not compatible, one observer familiar with the closed-door talks told journalists. The result is a grouping that can agree on the need to criticize the West’s role in the conflict but cannot formulate a common peace plan, let alone a shared strategic doctrine.

Two Unresolved Questions That Haunt the Summit

The Delhi summit has brought into sharp focus two immense gaps that prevent BRICS from moving from rhetoric to reality. First, there is no shared vision of what a “new global order” should actually look like. For some, it means a multipolar system with BRICS as a formal pole; for others, it means merely a more diffuse distribution of power that still operates within existing multilateral frameworks. Second, the bloc lacks any agreed-upon mechanism—or apparently even the appetite—to translate its broad principles into concrete, coordinated action.

The central dilemma facing the summit: BRICS members agree they need a new global order, but it is harder to answer what should replace it and how to get there.

The Iran war has only deepened these dilemmas. Would a reformed order permit Iran to pursue its regional ambitions free of Western pressure, or would it impose new multilateral constraints? Would BRICS nations be willing to pool their diplomatic and economic leverage to enforce a common stance, or would they continue to cut bilateral deals? The answer, so far, appears to be the latter.

Competing National Interests Undermine Bloc Ambitions

India, as the summit host, has found itself walking a tightrope. New Delhi maintains robust ties with Washington and European capitals while also nurturing its long-standing partnerships with Moscow and Tehran. The Iran war directly threatens India’s energy imports and connectivity projects—including the strategically vital Chabahar port—forcing it to prioritize national imperatives over any abstract notion of BRICS solidarity.

Similar calculations are evident across the grouping. China’s complex relationship with Iran, Russia’s own entanglement in the broader Middle Eastern dynamics, and Brazil’s desire to avoid being dragged into a conflict far from its shores all pull in different directions. Even the newer BRICS members, many of whom joined precisely to gain a seat at the global table, are discovering that collective power is difficult to wield when each member’s vital interests are at stake.

This internal fragmentation makes the Delhi summit a critical test of BRICS’ relevance. The joint declaration, expected on the final day, will likely paper over these cracks with language about “reforming multilateral institutions” and “strengthening cooperation.” But diplomats concede that the text will avoid any binding commitments or specific action points on Iran—precisely because no consensus exists.

Rhetoric Versus Reality: The BRICS Paradox

The 2026 summit encapsulates the enduring paradox of the BRICS project. On the surface, it is a gathering of nations that increasingly resent Western dominance and share a broad desire for change. Their statements resonate with large parts of the Global South, fueling a narrative of an emerging post-American world. But the substance lags far behind. The Iran war has shown that when a real-world crisis demands a real-world response, the bloc retreats into competing national positions.

Analysts note that the grouping remains defined more by what it opposes than by what it builds. The summit’s ritual denunciations of NATO, unilateral sanctions, and Western financial institutions are predictable and loud. Yet any attempt to sketch an alternative—a new reserve currency, a BRICS security framework, a collective mediation mechanism—stumbles immediately on the rock of diverging interests.

As the war in Iran grinds on, its ripple effects will continue to test the bloc. The Delhi summit has made one thing clear: a shared grievance is not the same as a shared strategy. Until BRICS can answer the dual questions of what should replace the current order and how to build it, the grouping will remain a loud chorus without a score—a political force whose reach repeatedly falls short of its rhetoric.
