Disinformation Emerges as New Tool in International Relations

In a striking display of how disinformation has evolved into a strategic diplomatic weapon, oil markets plunged nearly 11 percent on March 23, 2026, after US President Donald Trump claimed on Truth Social that Washington and Tehran were engaged in “productive negotiations.” Iran’s Foreign Ministry swiftly denied these claims, but the damage was already done—oil prices failed to recover at the same pace.

This incident represents a troubling shift in international relations, where disinformation has transformed from a domestic political tool into an instrument of statecraft with tangible economic consequences.

Unlike propaganda, which relies on ideology or selective facts, disinformation consists of deliberately false information created to cause harm or achieve specific objectives. While state-sponsored falsehoods have historical precedent—such as Bismarck’s editing of the Ems Dispatch in 1870 that helped trigger the Franco-Prussian War or Britain’s fabrication of the Zinoviev Letter in 1924—President Trump has expanded this approach to the global stage.

The March 2026 incident wasn’t isolated. During the US-China tariff war in 2025, President Trump employed similar tactics, claiming active negotiations between Washington and Beijing. In that instance, China’s Foreign Ministry immediately issued denials, limiting the market impact.

Analysts note a pattern in these false diplomatic announcements, particularly regarding Iran. According to Iranian academic Seyed Mohammad Marandi, “Every week, when markets open, President Trump makes such statements to drive down oil prices.” This strategy serves dual purposes: manipulating commodity markets while addressing domestic political concerns.

With the Strait of Hormuz effectively closed since February and US gasoline prices climbing, approximately 80 percent of Trump’s supporters favor a quick resolution to the Iran conflict. By creating the illusion of diplomatic progress, the administration can temporarily calm both markets and voters.

The consequences for international diplomacy are profound. Genuine diplomatic communication relies on credibility and trustworthiness—qualities undermined by deliberate falsehoods. When major powers deploy fabricated announcements to manage commodity prices and approval ratings, the entire diplomatic framework suffers.

“Every genuine diplomatic signal becomes harder to read when mixed with deliberate falsehoods,” explains Dr. Emma Reynolds, professor of international relations at Georgetown University. “It establishes a dangerous precedent where states might replace actual negotiation with disinformation campaigns.”

The collapse of recent US-Iran talks in Islamabad illustrates these consequences. Pakistan’s efforts at shuttle diplomacy were complicated by the atmosphere of distrust created through repeated false claims. Days before direct US-Iran negotiations were scheduled, Trump announced that Iran was requesting a ceasefire—a claim Tehran immediately rejected.

For countries like Pakistan that invest diplomatic capital in facilitating dialogue between adversaries, the manufacturing of fictional diplomatic progress creates significant obstacles. When one side repeatedly makes false assertions, building the necessary trust for meaningful negotiations becomes nearly impossible.

The international community now faces a critical challenge: how to preserve diplomatic norms in an era where powerful actors deliberately manipulate information for strategic gain. Without clear boundaries between political rhetoric and diplomatic communication, the global system for resolving conflicts peacefully faces unprecedented strain.

In today’s information ecosystem—where initial claims receive far more attention than subsequent corrections—powerful actors have discovered they can exploit this imbalance. When these tactics extend from domestic politics into international relations, they threaten the foundations of global diplomacy.

Experts warn that if left unchecked, disinformation as diplomatic strategy could become normalized, further eroding trust between nations. This would severely restrict the space for genuine negotiation precisely when complex global challenges demand more diplomatic engagement, not less.

The international community must now reckon with this evolution in statecraft, where the line between strategic communication and outright falsehood has blurred, potentially changing the nature of diplomacy itself.
