Gulf Cooperation Council

Overview

The Gulf Cooperation Council (GCC), formally the Cooperation Council for the Arab States of the Gulf, is a regional organization of six monarchies bordering the Persian Gulf: Saudi Arabia, Kuwait, Qatar, Bahrain, Oman and the United Arab Emirates. It was established on May 25, 1981, to advance coordination, cooperation and integration across economic, social, cultural, political and military affairs. Iraq has a Persian Gulf coastline but is not a member. The council gives its members a standing forum for collective decisions, although each government retains its own foreign and security policy.

The GCC emerged from long-standing trade ties, shared economic interests and earlier proposals for Gulf unity. Its members also faced immediate security concerns: the Iran–Iraq War threatened to spread across the region, while revolutionary Iran unsettled neighboring monarchies. Those circumstances made collective security a central concern from the outset. Over time, the council developed defense arrangements and a close strategic relationship with the United States, alongside programs for economic integration. It has also served as a diplomatic forum on conflicts in Iraq, Yemen and Syria.

Common interests have never produced a consistently unified bloc. Rivalry over Saudi influence, differing approaches to the Iranian regime and Qatar’s independent regional policy have strained relations. A dispute that began with the withdrawal of three ambassadors from Doha in 2014 escalated into a diplomatic, economic and transportation boycott in 2017. Members have also differed over relations with Israel, Hamas and Gaza. The GCC therefore remains both a framework for joint action and a venue in which competing national policies become visible.

Founding and ideology

Ideas of political unity among the Arab monarchies of the Gulf preceded the independence of some eventual GCC members. Governments had discussed Gulf security arrangements before Britain withdrew its forces from the region in 1971. Prolonged cooperation in trade and economics supplied a practical foundation for a more formal institution. Former Kuwaiti emir Shaykh Jabir al-Ahmed al-Jabir al-Sabah initiated the council, which the six governments established in 1981 amid the Iran–Iraq War. Their monarchical systems, close geographic setting and shared interest in regional stability helped make sustained cooperation possible.

The founding purpose was broad. Economic integration and stronger private-sector cooperation stood alongside social and cultural coordination and political consultation. Security was equally urgent. The war between Iran and Iraq placed fighting near the Gulf monarchies, and the Iranian Revolution had sharpened fears of regional upheaval. The council offered a means to discuss those threats and coordinate responses without merging its members into a single state. Its founding aim of integration across fields has continued to coexist with national control over diplomacy, armed forces and domestic policy.

Proposals for deeper political unity have exposed the limits of that model. Saudi King Abdullah later called for movement from cooperation toward a single entity, but the initiative did not secure agreement. Smaller members were concerned about Saudi dominance, and governments disagreed over the character of any closer union. The GCC’s governing idea is consequently cooperation among sovereign monarchies, expressed through summits and shared programs rather than a single Gulf government. That distinction helps explain why its economic and defense ambitions have advanced at different speeds.

History

Military coordination developed soon after the council’s founding. In 1984, members decided to create a unified regional force, subsequently known as the Peninsula Shield Force. The initial force placed approximately 10,000 troops from member states in Saudi Arabia. It was intended to deter attacks on GCC states and provide a means to coordinate their defense. Peninsula Shield was used during the 1991 liberation of Kuwait after Iraq’s invasion and deployed to Kuwait again in 2003 amid the Iraq War. In December 2000, members signed a joint defense agreement treating a threat to one state as a threat to all.

Economic integration remained a parallel ambition. Shared commercial interests had helped bring the council into being, and subsequent plans sought stronger links across the six economies. A proposed $16 billion railway would connect all six member states through a network of approximately 2,117 kilometers. Such projects reflect the council’s aim to make regional cooperation tangible through transport and trade. Financial circumstances can also draw members together: in 2018, Gulf donors conditioned a five-year aid package for Bahrain on spending restraint and increased non-oil revenue.

The GCC became an important setting for Gulf diplomacy during regional crises. In April 2011, it proposed a transition under which Yemeni president Ali Abdullah Saleh would transfer power to Vice President Abdrabbuh Mansour Hadi. The proposal offered Saleh immunity for legal infractions committed during his rule in return for stepping down within 30 days. Saleh accepted the agreement in principle but refused to sign it at least three times. The episode showed both the council’s ability to formulate a regional diplomatic proposal and the difficulty of securing its implementation.

Qatar’s relationship with the other members became a persistent source of tension. The 1995 transfer of power to Hamad bin Khalifa Al Thani marked the beginning of a more independent Qatari policy. The founding of Al Jazeera in 1996 gave that policy a prominent media platform. Qatar sought to limit Saudi dominance within the council and avoid conflict with the Iranian regime. In March 2014, Saudi Arabia, the United Arab Emirates and Bahrain withdrew their ambassadors from Doha over Qatar’s conduct within the GCC.

The breach widened in mid-2017, when Saudi Arabia, the United Arab Emirates and Bahrain severed diplomatic and commercial ties with Qatar. Egypt joined the wider boycott, which also restricted transportation links. Kuwait and Oman avoided taking sides. Kuwait’s Emir Sabah led mediation and called for GCC unity and dialogue. The rupture disrupted the premise that shared Gulf interests would reliably yield common policy. It also illustrated the economic costs that a retreat from integration could impose over time.

Structure and leadership

The GCC is an organization of governments, with its principal political direction set by the six member states. Its presidency rotates annually; Kuwait held the presidency in 2014. Regular meetings allow leaders, foreign ministers and defense officials to coordinate decisions, while the secretary-general represents the institution in regional diplomacy. In February 2025, Iranian regime foreign minister Abbas Araghchi met GCC Secretary-General Jassim Mohammed al-Badawi in Oman, illustrating the council’s role as a diplomatic counterpart even when its members differ in their approaches to Tehran.

Collective decisions depend on governments whose security priorities and regional partnerships are not identical. Saudi Arabia’s size and influence make its role central, but smaller members have resisted arrangements they regard as reducing their autonomy. Qatar’s independent course provides the clearest example. Kuwait’s mediation and Oman’s neutrality during the Qatar dispute demonstrate other ways members have used their positions within the council. These differences shape what the organization can accomplish: it can sustain consultation through a serious dispute, yet consultation alone does not guarantee a common policy.

Funding and sponsors

The GCC is sustained by its member governments, which sponsor its collective institutions and participate in its economic and security initiatives. Its role is distinct from that of a private movement or an armed organization dependent on an outside patron. Member governments also fund or support projects and assistance arrangements pursued through Gulf cooperation. The proposed regional railway and the conditional aid package for Bahrain show the range of financial commitments associated with that cooperation, from shared infrastructure to support for a member facing fiscal pressure.

GCC funding can also extend beyond the six states. A 2026 UN Watch report identified a $100,000 contribution from the council in 2025 to the office of the United Nations Special Rapporteur on Violence Against Women. The report questioned the independence implications of that funding. The contribution illustrates the organization’s ability to act financially in its own name, while the criticism shows that its external spending can draw scrutiny. It does not change the council’s underlying character as an institution of six governments with differing national budgets and priorities.

Attacks and operations

The GCC’s principal military instrument is the Peninsula Shield Force. Created as a collective defense force, it was deployed in connection with Kuwait’s liberation in 1991 and again to Kuwait in 2003. The 2000 joint defense agreement formalized the principle that a threat to one member concerns them all. These arrangements provide a basis for military coordination, but they have not erased differences in national threat assessments or produced a single foreign policy. GCC members have also participated in and supported the international coalition against the Islamic State in Iraq and Syria.

Security cooperation with the United States is a major part of the council’s operations. All six monarchies opened territory to U.S. military bases. The United States concluded formal defense cooperation or access agreements with every member except Saudi Arabia, whose arrangement was informal. As of 2014, approximately 35,000 U.S. military personnel served at more than a dozen Gulf bases. Qatar hosted the Combined Air and Space Operations Center, which coordinated American air operations across the broader Middle East, while Bahrain hosted the principal U.S. naval base in the region.

The GCC and the United States formed a Strategic Cooperation Forum in 2012. At the May 2015 Camp David summit, the United States and all six GCC members committed to a stronger regional partnership. Five working groups addressed counterterrorism, missile defense, military preparedness, defense transfers and cybersecurity. The partners also committed to joint maritime patrols and faster development of an integrated GCC ballistic missile early-warning system. U.S. and GCC defense ministers met in Riyadh on April 20, 2016, and agreed on additional security cooperation against the Islamic State.

At their 2016 Riyadh summit, U.S. and GCC leaders pledged to intensify efforts against the Islamic State and Al-Qaeda and to address destabilizing activity by the Iranian regime. Cooperation also included law-enforcement and financial measures aimed at disrupting Hezbollah, a terrorist organization, in the Gulf. In 2016, the Organisation of Islamic Cooperation and the Arab League denounced Hezbollah after the GCC blacklisted it. President Donald Trump’s 2017 Riyadh visit included meetings with King Salman, GCC leaders and leaders from other Arab and Muslim countries, continuing the U.S. practice of engaging the council collectively as well as its members individually.

Diplomacy over Yemen has remained another GCC activity. At a June 2024 meeting in Doha amid attacks by the Houthi movement, the council supported a comprehensive political settlement based on the GCC Initiative and its implementing mechanism, the outcomes of Yemen’s National Dialogue Conference and UN Security Council Resolution 2216. The meeting reflected the council’s continuing involvement in a conflict affecting Gulf security and maritime routes. Its support for a settlement framework followed the earlier, difficult attempt to negotiate Saleh’s departure.

Designations and international status

The GCC is a regional intergovernmental organization whose members are the six founding monarchies. It is neither a state nor a single military command, although it maintains collective defense arrangements. Its international standing comes from its member governments and its work with other states and organizations. U.S. presidents have met its leaders at dedicated summits, and its secretary-general conducts diplomacy with regional governments. In July 2022, Mohammed bin Zayed and King Abdullah II met President Joe Biden in Jeddah during a regional summit involving GCC states, Egypt, Iraq and Jordan.

The council’s positions can influence wider regional diplomacy without binding every member to the same bilateral relationship. GCC states have sought stronger ties with Iraq through diplomacy and reconstruction, partly to limit Iranian regime influence and the risk of an Islamic State resurgence. They have also participated in broader international discussions on Syria, including a Riyadh meeting on sanctions after the fall of Bashar al-Assad’s regime. During the Syrian civil war, several Gulf monarchies backed jihadist forces fighting Assad’s regime; those national policies should not be treated as a single GCC operation.

Current status

Concern over Iranian regime influence remains one of the council’s most persistent shared interests. At a security conference in Doha, GCC Secretary-General Abdul Rahman al-Attiya described Iran’s nuclear ambitions as a direct threat to Gulf states and NATO. Iranian ambitions also contributed to a practical rapprochement between Israel and GCC countries after the 2006 Lebanon war. Israel and individual Gulf members had maintained discreet engagement from the 1990s as security and trade interests drew them closer. Shared concern, however, has not removed differences among GCC governments over how to manage relations with Tehran.

Policies toward Israel, Hamas and Gaza likewise vary. Qatar supported Hamas’s rule in Gaza, setting its policy apart from those of other Gulf monarchies. Hamas is a terrorist organization that violently seized power in Gaza in 2007. Disagreements among GCC members prevented the council from establishing a joint Gaza policy. The distinction matters when assessing the organization: engagement with Israel, support for Hamas and positions on Gaza have been choices made by particular governments, rather than evidence of one settled GCC approach.

The GCC continues to convene on security, economic integration and regional crises despite those divisions. Its Yemen diplomacy in 2024, its continuing contacts over Iran and its participation in wider regional summits show that member governments still use the institution. The Qatar rupture demonstrated how sharply their policies can diverge, while Kuwait’s mediation and Oman’s neutrality showed that membership can also provide channels for dialogue during a breach. The council’s capacity for collective action remains strongest where its six governments agree on a specific goal and weakest where their national strategies conflict.
