Saudi-UAE rivalry explodes into view after strike in war-torn Yemen

For years, the United Arab Emirates and Saudi Arabia projected geopolitical and economic power across the Gulf and beyond, seemingly in tandem.\nBut a growing rivalry and struggle for influence has come to a head - most recently in Yemen - following years of divergence over a tangle of competing interests that reach from regional waterways to the corridors of power in Washington, analysts say.\nThe once-close relationship between Saudi Crown Prince Mohammed bin Salman and UAE President Sheikh Mohamed bin Zayed Al Nahyan was long seen as the backbone of the alliance between the two Gulf powers.\nBut as their ambitions grew apart and Prince Mohammed accelerated sweeping economic reforms at home while reasserting Saudi dominance abroad, talk has swirled of a rift with the Emirati leader, previously considered his mentor.\n\nNow the pair find themselves on opposing sides over oil production and in Sudan, the Horn of Africa and now Yemen, where the two countries are part of an anti-Houthi military coalition but support rival factions within the internationally recognised government.\nYemen and Gulf expert Baraa Shiban pointed to deep strategic and ideological differences, with Saudi Arabia alarmed by what it views as the UAE’s willingness in war-torn Yemen and Sudan to “break the country” by backing disruptive forces in a bid for influence, with Riyadh preferring instead to preserve existing authorities.\nHe also said there was an “obsession” among the Emirati leadership about fighting the Muslim Brotherhood and political Islam, a stance the UAE has sought to push across the region but which is not shared to the same degree by Saudi Arabia.\nSaudi Arabia is also keen to hold on to what it considers its own regional pre-eminence.\n“Seeing one country with huge influence, like the United Arab Emirates, crafting bilateral deals... suddenly having footholds in multiple countries with those non-state actors, it’s something they would be very concerned about,” Shiban said.\nThe countries’ opposition in Yemen burst into view recently when the separatist Southern Transitional Council (STC) - supported by the UAE and part of Yemen’s governing alliance - seized swathes of resource-rich Hadramawt and Mahra provinces from forces loyal to the government, backed by Saudi Arabia.\n\nJoint Forces Command of the Coalition to Restore Legitimacy in Yemen: Limited Airstrike Targeted Foreign Military Support in the Port of Mukalla.https://t.co/OttfQ8CGuu#SPAGOV pic.twitter.com/twFUiPPvkR\n— SPAENG (@Spa_Eng) December 30, 2025\n\nThe Saudi-led military coalition in Yemen, which it formed to fight the Houthi rebels and to which the UAE nominally belongs, on Tuesday bombed an alleged Emirati weapons shipment destined for the separatists.\nBut the cracks in the coalition had started to show years earlier, with the UAE pulling out the bulk of its forces in July 2019.\nUAE and Saudi aims in Yemen are “significantly different” and there is “no way to reconcile the two approaches”, Shiban said.\nIn November, US President Donald Trump promised to end a grinding war in Sudan following a request by Salman during a trip to Washington.\nAbu Dhabi has been widely accused of arming the paramilitary Rapid Support Forces (RSF), which have been fighting Sudan’s regular army since April 2023. The UAE has repeatedly denied the accusations.\nThe Sudanese army, meanwhile, has received support from Saudi Arabia.\n\nMiddle East and North Africa researcher Emadeddin Badi said it was difficult to view the STC’s advance in Yemen “as anything but retaliation by the UAE for (Salman’s) visit to Trump”, which he said was implicitly understood as Saudi Arabia pushing for a tougher stance on the UAE.\nThe Horn of Africa has become another arena of competition thanks to its strategic position, abutting the Red Sea, Gulf of Aden and Indian Ocean.\nThe UAE has fostered ties with Ethiopia and Somaliland, which seeks to break away from Somalia, and has operated a military base at the port of Berbera since 2017.\nSaudi Arabia, meanwhile, has sought to bolster Mogadishu.\nIsrael, which established ties with the UAE in 2020, last week recognised Somaliland in a move condemned by Saudi Arabia and 20 other mostly Muslim countries. The UAE did not join in the condemnation.\nBadi said the recognition would have been a “trigger that amplified the threat perception on the Saudi side”.\nSomaliland could later look to recognise Israel, “which is something that the UAE intends to leverage”, he added.\nFollowing a spat between the UAE and Saudi over Opec output curbs in 2021, economic rivalry has sharpened as both seek to diversify away from oil.\nRiyadh has since moved aggressively to attract multinationals, requiring companies that do business with government agencies to base their regional headquarters there, prompting some to relocate from the UAE.\nThe push under Saudi Arabia’s Vision 2030 national blueprint has extended to aviation, tourism and media, with Saudi Arabia launching a new airline, airport and leisure projects to rival Dubai’s established hubs.\nIn recent weeks Riyadh has also quietly relaxed its laws to allow wealthy, non-Muslim foreign residents to purchase alcohol - seen as another bid to attract overseas workers who would otherwise be drawn to the UAE.\n
