Pakistan’s Mediation Between the U.S. and Iran Reflects Profound Evolution of the International Landscape

The military conflict involving the United States, Israel and Iran has triggered an abrupt deterioration of the geopolitical security situation in the Middle East. Amid widespread international concerns over an uncontrolled escalation, Pakistan took the initiative to mediate, conveying messages and coordinating positions between Washington and Tehran. This ultimately led to a temporary ceasefire taking effect on April 8, 2026, and the convening of the first round of talks in Islamabad. After playing a pivotal role as a crucial bridge for Henry Kissinger’s secret visit to China in 1971, Pakistan has once again emerged as a "middleman" in major-power relations, becoming a significant variable driving the restructuring of the international order. 

I.Why Has Pakistan Become the Core Mediator in the U.S.-Iran Conflict? 

Pakistan hosts no U.S. military bases and is one of the few U.S. partners not targeted by Iran’s missiles and drones. This unique status has led Iran to view Pakistan as a relatively neutral, secure, and reliable platform for dialogue. Against the backdrop of a complete breakdown of trust between the U.S. and Iran, where no third party with military alliance ties can gain simultaneous acceptance from both sides, Pakistan’s neutral stance has significantly enhanced its credibility and acceptability as a mediator. 

In terms of Pakistan-Iran relations: Iran was the first country to recognize Pakistan’s independence, laying a solid foundation of historical mutual trust. Pakistan is home to the world’s second-largest Shia population, sharing religious roots and cultural affinities with Iran, which naturally fosters a sense of strategic closeness. Since the U.S. and Iran severed diplomatic ties in 1979, the Pakistani Embassy in Washington has permanently housed Iran’s Interests Section, handling part of Iran’s diplomatic affairs in the U.S. and forming a stable channel for information exchange. Regarding Pakistan-U.S. relations: bilateral ties have warmed markedly since the second term of the Trump administration. In 2025, Pakistan’s Army Chief General Munir was invited to the White House for a luncheon with Trump—the first time a U.S. president has hosted a non-head-of-state military leader at such a level. Trump publicly praised Pakistan for "understanding Iran better than most countries," providing crucial political endorsement for Islamabad’s mediation efforts. 

Pakistan’s proactive push for a ceasefire and dialogue is essentially an inevitable choice to safeguard its own security and economic interests. Geopolitically, the Pakistan-Iran border stretches nearly 1,000 kilometers; a full-scale U.S.-Iran war would directly spill over to destabilize Pakistan’s border regions and national security. For energy security, Pakistan is highly dependent on Middle Eastern oil imports with extremely limited crude and refined product reserves—any disruption to navigation in the Strait of Hormuz would directly threaten the country’s energy lifeline. Economically, approximately 5 million Pakistani citizens work in the Gulf region, with remittances forming a vital pillar of foreign exchange earnings. A prolonged war would severely damage these remittances and trigger large-scale unemployment and return migration. 

II.The Historical Continuity of Pakistan’s "International Mediation Gene" 

Pakistan’s role in building a dialogue bridge between the U.S. and Iran is not an isolated diplomatic event, but a reaffirmation of its historical experience of leveraging its crossroads geopolitical advantage to act as a "middleman" in major-power relations. 

In July 1971, during a visit to Pakistan, then-U.S. National Security Advisor Henry Kissinger secretly flew from Islamabad to Beijing, completing a historic trip that reshaped the Cold War landscape. This breakthrough broke 22 years of frozen Sino-U.S. relations, paving the way for President Nixon’s visit the following year and profoundly restructuring the global strategic map. In this diplomatic feat for the history books, then-Pakistani President Yahya Khan played an irreplaceable role as messenger and facilitator. It was his continuous message transmission between Washington and Beijing that forged the initial bond of trust. Nixon explicitly noted in his memoirs that without Pakistan’s assistance, the timeline for Sino-U.S. engagement would have been significantly delayed; Kissinger himself acknowledged Islamabad’s role as "irreplaceable." 

Furthermore, during the Soviet invasion of Afghanistan, Pakistan served as the core conduit for U.S. aid to Afghan resistance forces while maintaining diplomatic contacts with the Soviet Union, deeply participating in UN-led Geneva negotiations. When the U.S. and the Afghan Taliban signed the Doha Agreement in 2020, Pakistan’s behind-the-scenes facilitating role was widely recognized by the international community. 

III.A Profound Reflection at the Crossroads of a Century of Transformation 

From brokering the Sino-U.S. Cold War thaw in 1971 to mediating an end to U.S.-Iran military hostilities in 2026, Pakistan once again stands at a critical juncture in global structural transformation. Its "bridge diplomacy" spanning more than half a century clearly reflects that the international order has reached a new crossroads of profound changes unseen in a century.

 In 1971, the world was in a period of loosening bipolar U.S.-Soviet structure, and Sino-U.S. rapprochement represented a major recalibration of the global power balance. Located at the intersection of U.S., Chinese, and Soviet spheres of influence, Pakistan naturally became a key catalyst for this realignment, exerting a profound impact on the reshaping of the Cold War geopolitical order. Today, the international system is undergoing the most profound structural transformation since the end of the Cold War. Structural tensions between the inertia of U.S. global hegemony and multipolarity continue to intensify; the traditional Middle Eastern security architecture is disintegrating; multiple risks including nuclear proliferation and energy security are intertwined; and traditional crisis management mechanisms are increasingly strained. Pakistan’s being thrust into the spotlight as a key force for de-escalation is the most vivid testament to the deep restructuring of the global power landscape. 

Notably, the U.S. seeking Pakistan’s mediation essentially signals a severe setback to the U.S.-Israel strategy of joint military strikes against Iran. Washington and Tel Aviv initially sought to coerce Iran through unilateral military deterrence to consolidate their Middle Eastern dominance, but ultimately became trapped in a strategic impasse of escalating military confrontation, absent regional allies, and international isolation—forcing them to turn to third-party mediation to limit losses. This outcome fully exposes the limitations of U.S.-style military deterrence, marking the declining efficacy of the unilateralist diplomatic paradigm of resorting to force at will, and the irreversible relative decline of U.S. unipolar hegemony. （Author: Ding Xinting and Zhu Yueyao, South Asia Institute, China Institutes of Contemporary International Relations (CICIR)）
