That gap between rhetoric and action reflects a blunt calculation in Moscow and Beijing: both still see Iran as useful, but neither appears willing to risk a direct clash with Washington or sacrifice ties with Gulf Arab states to save Tehran.
Iran war reveals the limits of strategic partnerships
As Reuters reported Saturday, the conflict that began with U.S. and Israeli strikes on Feb. 28 has entered its second week, spread into Lebanon and Gulf states, and pushed oil markets higher as the Strait of Hormuz has effectively shut. For Tehran, the military pressure is severe; politically, the more important shock may be that its two most powerful partners are still standing outside the fight.
A Reuters analysis published this week found that Russia and China had offered Iran little beyond condemnations, calls for talks and back-channel diplomacy. Tehran spent years building those relationships as a hedge against Western pressure, but the war is showing that strategic alignment is not the same thing as a wartime guarantee.
Why Russia and China are holding back in the Iran war
Moscow is still consumed by Ukraine and has little incentive to open a direct confrontation with the United States while trying to preserve working ties with Israel and Gulf Arab states. Beijing, meanwhile, has stayed inside its familiar lane of trade, energy security and mediation; this week, it said it would send a special envoy to the Middle East rather than signal any military commitment.
That restraint does not mean the relationship is meaningless. AP reported Friday that Russia has provided information that could help Iran strike U.S. assets in the region, a reminder that indirect help can coexist with strategic caution. But even that kind of reported support falls well short of the overt intervention Tehran might have hoped for from powers that publicly present themselves as alternatives to the U.S.-led order.
Older promises, thinner guarantees
The contrast is sharper because both relationships were sold as long-horizon realignments. In 2021, Beijing and Tehran signed a 25-year cooperation agreement meant to deepen economic and political ties. In January 2025, Moscow and Tehran signed a 20-year strategic partnership treaty that expanded defense cooperation but stopped short of a mutual-defense pact.
Those agreements were significant, but they also contained Tehran’s problem in fine print. Arms sales, investment, intelligence ties and diplomatic cover are easier to promise than battlefield rescue when U.S. firepower, Gulf energy routes and wider regional stability are at stake.
What Tehran’s isolation means next
Iran may still receive rhetorical backing, mediation offers and selective behind-the-scenes assistance. What it has not received is a second front opened by Russia or China, a coalition naval move, or any public sign that either power is ready to absorb the military and economic costs of joining the war outright.
For Tehran, that may be the bleakest lesson of the Iran war so far. The Islamic Republic cultivated major-power ties as insurance against exactly this kind of crisis. Under fire, that insurance now looks limited, transactional and, when it matters most, painfully incomplete.
