The Gulf Cooperation Council (GCC) is a political, economic, and security alliance of six Arab monarchies in the Persian Gulf: Saudi Arabia, the United Arab Emirates, Qatar, Kuwait, Bahrain, and Oman. The six countries together cover approximately 2.5 million square kilometres of the Arabian Peninsula and contain about 60 million people. Despite their relatively small combined population (smaller than Italy), they wield substantial global influence — they control approximately 40 percent of the world's proven oil reserves and 35 percent of natural gas reserves; they are among the world's largest sovereign wealth fund managers; they host major American military bases; and they are key players in Middle Eastern politics, energy markets, and Islamic religious affairs. The GCC was founded in 1981 and has evolved into one of the more successful regional cooperation organisations in the developing world, though one that has had its share of internal tensions and external challenges.
The Member States
The six GCC members are quite varied despite their shared characteristics as Arab monarchies in the Persian Gulf. Saudi Arabia is by far the largest — about 2.15 million square kilometres in area (much of it desert) and approximately 36 million people. The United Arab Emirates is a federation of seven emirates with a population of about 10 million, of whom about 1 million are citizens; the rest are foreign workers. Qatar is small in area (11,500 km²) but wealthy from natural gas, with about 3 million people of whom about 350,000 are citizens. Kuwait has approximately 4.5 million people and is the second-richest country in the world by per capita income on some measures. Bahrain is the smallest by area (760 km²) and one of the smaller by population (about 1.7 million); it is the only GCC monarchy that is a constitutional monarchy with a parliament. Oman is the second-largest in area (310,000 km²) and population (about 5 million); it is the most culturally and politically distinct of the GCC states, with a different religious tradition (Ibadi Islam rather than Sunni or Shia) and a more independent foreign policy.
The Foundation
The GCC was founded on 25 May 1981 at a summit meeting in Abu Dhabi, in the immediate aftermath of the Iranian Revolution (1979) and the start of the Iran-Iraq War (1980). The founding members saw a clear need for cooperation against the perceived threat from Iran (now under revolutionary Shia clerical rule) and the destabilising war in the broader region. The original goal was primarily economic and political coordination, with security cooperation being more limited. Over the subsequent decades, the GCC has expanded its scope into a comprehensive cooperation framework. It established a customs union in 2003, a common market in 2008, and various other integration measures. The original goal of a unified GCC currency has been repeatedly proposed but never implemented, with various countries having different views on the appropriate timing and conditions.
Energy Wealth
The GCC's economic and political importance is overwhelmingly tied to its energy resources. Saudi Arabia is the world's second-largest oil producer (after the US) and the largest oil exporter. The UAE, Qatar, and Kuwait are also major oil and gas producers. Qatar alone holds approximately 13 percent of the world's natural gas reserves and is the world's largest exporter of liquefied natural gas (LNG). Together, the six countries account for approximately 40 percent of proven world oil reserves and 35 percent of proven natural gas reserves. The fossil fuel exports have generated enormous wealth — Saudi Arabia's 2022 oil exports were over $300 billion; the UAE's about $100 billion; Qatar's about $80 billion. The sovereign wealth funds of the GCC states collectively manage approximately $4 trillion in assets — among the largest pools of investable capital in the world. The Public Investment Fund of Saudi Arabia, the Abu Dhabi Investment Authority, the Qatar Investment Authority, and the Kuwait Investment Authority are among the largest sovereign wealth funds globally.
Economic Diversification
All six GCC states have launched substantial economic diversification efforts to reduce dependence on oil and gas. Saudi Arabia's Vision 2030, launched in 2016, aims to transform the economy through investments in tourism, entertainment, renewable energy, technology, and various other sectors. The construction of NEOM — a $500 billion futuristic city in northwestern Saudi Arabia — is one of the largest single development projects ever proposed. The UAE has been more advanced in diversification, with Dubai having developed substantial tourism, aviation (Emirates and Etihad airlines), financial services, real estate, and trade. Abu Dhabi has invested heavily in renewable energy, semiconductors, and various other sectors. Qatar has hosted the 2022 FIFA World Cup as part of its broader effort to develop tourism and international visibility. The success of these diversification efforts will substantially shape whether the GCC states can maintain prosperity as the global energy transition reduces demand for fossil fuels.
Foreign Workers
The GCC states have an unusual labour market structure. Foreign workers — primarily from South Asia, the Philippines, and East Africa — constitute the majority of workers in most GCC states and the majority of the total population in several. The UAE's foreign population is approximately 88 percent of total residents; Qatar's is 88 percent; Kuwait's is 70 percent. These workers — including construction labourers, domestic workers, hospitality workers, healthcare workers, and various professionals — are typically employed on time-limited contracts under the "kafala" sponsorship system. The kafala system has been substantially criticised for various abuses, and reforms have been implemented in several countries, though enforcement and full implementation remain challenges. The economic structure depends on this foreign workforce, and the GCC has had limited success in significantly increasing the participation of native citizens in the private sector workforce.
The 2017 Qatar Crisis
One of the major events in GCC history was the 2017-2021 diplomatic crisis between Qatar and other GCC members. In June 2017, Saudi Arabia, the UAE, Bahrain, and Egypt (the latter not a GCC member) abruptly severed diplomatic relations with Qatar, imposed an air, sea, and land blockade, and made various demands of the Qatari government related to Iran relations, Al Jazeera, Muslim Brotherhood, and other issues. The blockade lasted until January 2021. Qatar weathered the blockade with substantial economic resilience, drawing on its sovereign wealth and developing alternative trade routes. The crisis substantially damaged the GCC's reputation as a unified bloc and revealed substantial internal tensions, though it ended without Qatar making the demanded concessions. The post-2021 GCC has been more outwardly cooperative but the underlying tensions have not been fully resolved.
Religious and Cultural Influence
Saudi Arabia is the spiritual centre of Sunni Islam — Mecca and Medina are the two holiest cities in Islam, both in Saudi Arabia. The Saudi government bears the title "Custodian of the Two Holy Mosques," reflecting its role in protecting and managing these sites. The annual Hajj pilgrimage brings approximately 2.5 million Muslims from around the world to Mecca. The lesser Umrah pilgrimage brings several million more annually. The cultural and religious influence of Saudi Arabia extends well beyond the GCC, shaping Islamic practice and education in many countries through Saudi-funded mosques, madrassas, and educational institutions. The other GCC states have their own religious traditions — Bahrain has a substantial Shia population (about 60 percent of citizens are Shia, while the ruling family is Sunni); Oman is predominantly Ibadi (a third major branch of Islam distinct from Sunni and Shia). The diversity of religious practice within the GCC is sometimes underappreciated.
Foreign Policy
GCC foreign policy is shaped by several major themes. The relationship with the United States is foundational — all six GCC states host US military forces (Bahrain hosts the US Fifth Fleet; Qatar hosts Al Udeid Air Base, the largest US military installation in the Middle East; Kuwait, UAE, Oman, and Saudi Arabia have other US facilities). The relationship with Iran is similarly important and has varied across the members — Saudi Arabia and UAE have generally been hostile to Iran while Qatar and Oman have maintained more constructive relations; Bahrain (with its Shia majority) has been particularly concerned about Iranian influence. The relationship with Israel has shifted substantially with the 2020 Abraham Accords (UAE and Bahrain normalised relations with Israel, with Saudi Arabia in various stages of consideration). The conflict in Yemen — where Saudi Arabia and UAE have led a coalition against the Houthi rebels since 2015 — has been a major preoccupation. The GCC's relationships with China, Russia, India, and other powers have substantially diversified over the past decade.
The Mohammed Bin Salman Era
Saudi Arabia's Crown Prince Mohammed bin Salman (commonly known as MBS) has been the most prominent GCC leader since approximately 2017. As Crown Prince and effectively the ruling figure under King Salman (since 2017) and now Prime Minister (since 2022), MBS has driven Vision 2030, the Yemen war, the 2017 Qatar crisis, the 2018 Khashoggi murder, the 2020 Abraham Accords negotiations, and various other developments. His domestic policies have included the curtailment of religious police powers, permission for women to drive, opening of the country to tourism, hosting of major sporting events, and substantial entertainment-sector development. They have also included substantial repression of dissent, including the imprisonment of activists, religious figures, and (in the Khashoggi case) the murder of a critical journalist. MBS's policies have substantially transformed Saudi Arabia and the broader GCC, though with substantial controversy.
The Future
The GCC's next decade will be shaped by several major forces. The global energy transition will continue to challenge the underlying economic basis of the GCC states. The success or failure of the various diversification efforts will determine whether the GCC can maintain prosperity in a lower-oil-demand world. The relationship with the US is in flux — both sides recalibrating after various tensions and the broader shift in US Middle East policy. The relationship with Iran has been partly normalised through Chinese-mediated diplomacy in 2023 but remains tense. The Yemen war's eventual resolution remains uncertain. The Israeli-Palestinian situation continues to constrain GCC normalisation efforts with Israel. The internal political evolution of the GCC monarchies — particularly the question of generational transitions in royal families — will substantially shape regional politics.
