Abstract:
The rivalry between Saudi Arabia (KSA) and the United Arab Emirates (UAE) has overtly manifested in a recent escalation of the Yemen conflict. The conflict centers on the UAE's support for the Southern Transitional Council (STC), a separatist faction that briefly captured territory from KSA-backed government forces in late 2023, prompting Saudi airstrikes. This incident highlights the dramatic deterioration of the relationship between Crown Prince Mohammed bin Salman (MBS) and President Mohammed bin Zayed (MBZ). The underlying tension is driven by intensified economic competition (Vision 2030 vs. Vision 2031) and fundamentally diverging foreign policies. While KSA pursues regional de-escalation, the UAE is building a network of non-state proxies across the Middle East and Africa (Yemen, Sudan, Somalia) to project power, secure access to resources, and gain influence over critical maritime chokepoints in the Red Sea and Gulf of Aden. Despite a recent de-escalation in Yemen, the exposure of this rivalry suggests a coming realignment that could reshape the region.
Summary of Saudi-UAE Tensions and Regional Proxy Conflicts
0:02 Yemen Conflict Eruption: The silent rivalry between KSA and the UAE became public when the UAE-backed Southern Transitional Council (STC)—a separatist faction—captured territory from KSA-backed Yemeni government forces.
0:15 Saudi Retaliation: The STC's advance prompted KSA to execute a series of air strikes, including one targeting a shipment the Saudis identified as weapons destined for the STC from the UAE at the southern port of Macala (0:18, 2:10). The UAE denied the shipment was for combat purposes.
1:15 STC Separatist Objective: The STC, a key faction within the fragile, KSA/UAE-backed Presidential Leadership Council (PLC), seeks an independent state of South Yemen, an outcome opposed by Saudi Arabia.
1:47 December 2023 Offensive: The STC launched a rapid military offensive in early December, seizing territory up to the Saudi border, including the oil-rich Hadramot province (2:00).
2:31 Immediate De-escalation: Under pressure from KSA, the UAE voluntarily withdrew its small troop presence from Yemen, allowing Saudi-backed forces to push the STC back and retake the captured provinces in a matter of days.
3:03 Historical Context of Alliance: Approximately a decade prior, KSA and the UAE maintained a close alliance, aligned on opposing Iran's influence, countering Islamism, and managing post-Arab Spring instability (3:06). This cooperation included the 2015 Yemen intervention and the 2017-2021 blockade of Qatar.
3:37 Signs of Rift: Early indicators of the rift include a 2021 dispute over OPEC oil production caps and the noticeable absence of MBZ from key regional summits in Riyadh (2022) and the Arab League summit (2023).
3:56 Core Drivers: The rivalry is fueled by intense economic competition—KSA's Vision 2030 and UAE's Vision 2031 both aim to diversify beyond oil and become the region's top hub (4:00).
4:16 Diverging Foreign Policy: Tensions are most evident in diverging foreign policies, with the UAE building a network of non-state actors across the Middle East and Africa (Yemen, Sudan, Somalia) to increase its regional influence (4:18).
4:35 Sudan Proxy Conflict: The UAE is identified as the primary backer of the Rapid Support Forces (RSF), a paramilitary group fighting the Sudanese military, with which KSA is aligned. The RSF faces international condemnation for alleged genocide (4:40).
5:00 Somalia/Somaliland Divergence: The UAE is silent on KSA-led Arab and Muslim condemnation of Israel's recognition of Somaliland (5:16). The UAE maintains significant interests in Somaliland, including a nearly $450 million investment by DP World in the Berbera port and a deal for an Emirati military base (5:29).
5:48 UAE Strategic Goals: The UAE's assertive foreign policy seeks access to resources (fertile farmland, gold in Sudan) and, crucially, influence over key maritime shipping routes (Red Sea, Gulf of Aden) to project political, economic, and military power (6:07).
6:31 Saudi De-escalation Strategy: KSA, under MBS, is attempting to lower regional temperature (ending the Qatar blockade, truce in Yemen, restoring ties with Iran) to focus internal resources on domestic transformation (6:40).
7:06 Outlook: While neither KSA nor the UAE appears to seek further direct confrontation, the public nature of the rivalry and their conflicting strategies in multiple arenas pose a sustained risk to regional stability.
