Saudi Arabia is a critical but cautious actor in the ongoing Israel–U.S. war against Iran. While not the primary mediator, its role as a regional stabiliser and its refusal to allow its territory for offensive strikes against Iran are pivotal to any resolution. Pakistan has emerged as the leading neutral mediator, hosting high-level U.S.–Iranian talks in Islamabad, including a conditional two-week ceasefire in early April 2026.
The Kingdom focuses on bilateral de-escalation with Iran to prevent broader conflict. High-level Riyadh–Tehran talks began in March 2026 to discuss humanitarian corridors and the protection of Persian Gulf energy infrastructure. Saudi Arabia has officially rejected the use of its airspace or territory for military action against Iran, seeking to preserve its 2023 détente. Along with Oman, Egypt, and Turkey, it continues back-channel communications between Washington and Tehran.
Prolonged war threatens Crown Prince Mohammed bin Salman’s Vision 2030. Attacks on energy infrastructure and the closure of the Strait of Hormuz have severely impacted Saudi oil exports, prompting the Kingdom to prioritise the peaceful reopening of the waterway. Despite preferring peace, Saudi officials remain wary of a nuclear-armed Iran.
Negotiations are currently stalled. President Trump recently cancelled an envoy trip to Pakistan, citing a lack of Iranian responsiveness. Nonetheless, Saudi “Hajj diplomacy” continues—direct flights for Iranian pilgrims resumed on 25 April 2026, signalling the commitment to functional ties despite wartime conditions.
Saudi Arabia remains dominant in the Organisation of Islamic Cooperation (OIC), leveraging its religious status and financial weight. As Custodian of the Two Holy Mosques, Riyadh holds unparalleled religious legitimacy, framing initiatives like the “Holy Sites Journey” as Islamic solidarity. The OIC is headquartered in Jeddah, and Saudi Arabia is its primary financial sponsor, influencing administrative and developmental priorities.
However, the OIC is primarily a non-political association focused on culture and humanitarian aid. It lacks enforcement mechanisms, and member states are often divided by mutual distrust and conflicting interests. In the current war, Saudi Arabia uses the OIC to build consensus for de-escalation.
To unite Muslim countries, Saudi Arabia combines religious legitimacy with “niche diplomacy” and multi-alignment, shifting from confrontation to stability to protect Vision 2030. By maintaining ties with the U.S., China, Russia, and the Global South, Riyadh positions itself as a bridge-builder, mediating conflicts such as the U.S.–Iran conflict or the Russia–Ukraine war.
By spearheading OIC revival and forming middle-power blocs, the Kingdom shifts from reliance on external security umbrellas to collective regional stability
Sustaining the 2023 rapprochement with Iran is vital. In March 2026, Saudi Arabia hosted an emergency OIC ministerial meeting in Riyadh to coordinate a unified response to regional threats. A proactive approach includes formalising security ties with other major Muslim powers—ongoing discussions involve a broader defence pact with Pakistan, Turkey, and Egypt. Pakistan has proposed expanding its bilateral pact with Saudi Arabia into a multilateral security framework. Through the “King Salman Humanitarian Aid and Relief Centre (KS Relief)”, Saudi Arabia reinforces its benefactor image, providing billions in aid globally.
A powerful new regional coordination framework has emerged involving Saudi Arabia, Turkey, Egypt, and Pakistan to navigate the current crisis. This “Quadrilateral” bloc combines Saudi religious legitimacy as Custodian of the Two Holy Mosques, Turkey’s NATO-standard military, Egypt’s demographic weight, and Pakistan’s nuclear capabilities.
Their goal is a negotiated settlement to the Israel–U.S. war against Iran and resisting a post-war order dictated solely by external powers or Iranian proxies. In March and April 2026, foreign ministers from these four nations held consultations in Islamabad and Antalya. Discussions are underway to expand bilateral defence pacts into a broader alliance. Indonesia and Malaysia are increasingly integrated as secondary facilitators, providing a neutral Asian perspective and building trust between Iran and Gulf countries.
China has transitioned from a “quiet broker” to a more active, cautious “backroom mediator”. It provides political weight that makes regional de-escalation possible, focusing on a balancing act that protects its energy security while challenging U.S. dominance through diplomacy. China and Pakistan proposed a Five-Point Initiative for Gulf stability.
On 14 April 2026, President Xi introduced a four-point plan emphasising peaceful coexistence and a “common security architecture”. As Iran’s largest oil buyer, China pressures Tehran to avoid wider escalation. For middle powers like Saudi Arabia, China offers a neutral alternative to hegemonic powers, though it may not provide physical security guarantees. The Trump administration has shown little enthusiasm for Chinese-led mediation. Nevertheless, China acts as a strategic guarantor behind the scenes, keeping fragile ceasefires alive while regional partners handle front-facing negotiations.
Saudi Arabia’s manoeuvres are proving highly beneficial for regional peace and security. By spearheading OIC revival and forming middle-power blocs, the Kingdom shifts from reliance on external security umbrellas to collective regional stability. Its proactive use of the OIC has restored its image as the undisputed leader of the Muslim world. The drive for peaceful coexistence is deeply tied to Vision 2030—de-escalating with Iran mitigates threats to the Strait of Hormuz, vital for oil exports, and attracts foreign investors.
The formation of the Quadrilateral Consultations marks the most significant manoeuvre for regional peace. All four nations are members of the 2026 Board of Peace, focused on lasting peace and reconstruction in Gaza. The revival of the OIC is driving a new multiplex order in the Middle East—defined not by a single superpower but by overlapping layers of regional authority, middle-power leadership, and multi-alignment. Saudi Arabia’s role is evolving into that of an influential broker in the Middle East.
