Saudi Arabia's Regional Reset: Iran, Yemen, Qatar, the UAE, and the New Gulf Balance

Crown Prince Abdullah's Arab Peace Initiative offered Arab normalization with Israel in exchange for Israeli withdrawal from territories occupied in 1967 and acceptance of an independent Palestinian state with East Jerusalem as its capital. The initiative became the formal Arab League framework for linking normalization to Palestinian statehood. It also established the long-term Saudi position that Israel ties could be strategic, but not formally detached from Palestine.

The fall of Saddam Hussein removed a Sunni Arab buffer state and created a new political arena in which Iranian influence expanded through parties and militias. Saudi Arabia gradually sought to rebuild ties with Iraq as a counterweight to Iranian influence. The 2017 Saudi-Iraqi Coordination Council became an institutional expression of that later reset.

Saudi Arabia led a coalition into Yemen after the Houthis seized Sanaa and advanced against the internationally recognised government. UN Security Council Resolution 2216, adopted in April 2015, demanded Houthi withdrawal from seized areas and imposed targeted sanctions and arms embargo measures. Yemen became Saudi Arabia's most direct border-security conflict and the main theatre where Riyadh framed Iranian influence as an immediate military problem.

Saudi Arabia severed diplomatic ties with Iran after protesters attacked Saudi diplomatic missions in Tehran and Mashhad following Riyadh's execution of Shia cleric Nimr al-Nimr. The rupture formalised a period of open confrontation. It also hardened the regional bloc logic that shaped later conflicts in Yemen, Lebanon, Syria, Bahrain, and Qatar.

Saudi Arabia, the UAE, Bahrain, and Egypt cut ties with Qatar and issued demands including closing Al Jazeera, ending the Turkish military presence, severing alleged links to Islamist groups, and scaling down diplomatic relations with Iran. Qatar rejected the demands as an infringement on sovereignty. The blockade showed that Saudi regional pressure was not limited to Iran-aligned actors; it also targeted independent Gulf policies that Riyadh and Abu Dhabi judged destabilising.

Drone and missile strikes hit Saudi Aramco's Abqaiq oil processing plant and Khurais field, initially knocking out 5.7 million barrels per day of Saudi oil production and 0.7 million barrels per day of natural gas liquids. The attack underscored that Saudi Arabia could face severe strategic damage even without a conventional Iran-Saudi war. It became one of the strongest material incentives for later de-escalation.

Saudi Arabia announced the Riyadh Agreement between Yemen's internationally recognised government and southern separatists after clashes inside the anti-Houthi camp. The deal sought to fold southern separatists into a power-sharing framework and preserve the coalition against the Houthis. The episode foreshadowed a recurring problem inside the anti-Houthi camp: southern separatists fought alongside the recognised government against the Houthis while also seeking a separate southern state.

Bahrain, Egypt, Kuwait, Oman, Qatar, Saudi Arabia, and the UAE concluded the Al-Ula Declaration on 5 January 2021. The agreement restored formal Gulf ties after the Qatar blockade. It did not erase disputes over media, Islamists, Turkey, and Iran, but it marked Saudi Arabia's first major post-2017 shift toward de-escalation inside the GCC.

President Recep Tayyip Erdogan's visit to Saudi Arabia marked a major step in repairing relations damaged by Turkey's support for Qatar during the blockade, its backing of Islamist movements, and the fallout from Jamal Khashoggi's murder in Istanbul. CFR described the trip as part of Turkey's broader effort to break out of regional isolation by restoring ties with the UAE, Israel, Egypt, and Saudi Arabia.

Saudi Arabia and Iran, with China as host and sponsor, announced an agreement to resume diplomatic relations, reopen embassies and missions within two months, and revive their 2001 security cooperation agreement and 1998 general cooperation agreement. Iraq and Oman were credited for earlier dialogue rounds. The agreement was a formal diplomatic reset, not a settlement of all proxy conflicts.

Bashar al-Assad attended the Arab League summit in Jeddah after Syria's readmission to the bloc. Al Jazeera reported that Saudi Arabia had previously been a key backer of armed opposition groups seeking to overthrow Assad, and that Syria's Arab League return signalled the end of Assad's regional isolation. The event documented a major Saudi-hosted diplomatic reversal from isolation to Arab engagement.

The second China-Saudi Arabia-Iran Trilateral Joint Committee met in Riyadh on 19 November 2024. Saudi Arabia and Iran reaffirmed commitment to the Beijing agreement, noted progress in consular services for Iranian pilgrims, and supported a political solution to Yemen under UN auspices. The meeting documented continued official engagement despite the regional escalation after October 2023.

The Southern Transitional Council, described by AP as an umbrella of armed groups trained and financed by the UAE, expanded across southern Yemen and seized areas in Hadhramaut including Seiyun, oil fields, energy installations, PetroMasila facilities, the presidential palace, and the international airport. A Yemeni official said the Saudi-led coalition briefly withheld flight permissions to and from Aden as a signal after the takeover. AP described the episode as exposing a growing rift between Saudi Arabia and the UAE inside the anti-Houthi coalition.

AP reported that the STC announced the dismantling of its bodies after weeks of unrest, internal divisions, and regional pressure, while Saudi-backed forces regained control of Hadhramaut, Aden's presidential palace, and camps in al-Mahra. AP also reported that STC moves on Saudi Arabia's borders were viewed as a threat to the kingdom's national security. A UK House of Commons Library briefing said a January 2026 counter-offensive recovered all STC territorial gains and that the UAE withdrew its remaining forces from Yemen.

The UK House of Commons Library assessed that Yemen's frontlines had been largely frozen since the 2022 ceasefire, but that the balance of power inside anti-Houthi forces changed rapidly from December 2025 to January 2026. The Houthis remained largely unaffected by the southern reordering. The episode documented that Yemen's instability extends beyond the Saudi-Iran axis into disputes inside the anti-Houthi camp.
