Saudi Arabia Escalates Strategic Posture Amid Growing Rift With UAE Over Yemen and Red Sea Influence
Riyadh’s moves in Yemen and regional security mark a deepening geopolitical competition with Abu Dhabi that extends to the Red Sea corridor
Saudi Arabia has taken a more assertive stance in Yemen and the broader Red Sea region as its strategic relationship with the United Arab Emirates shifts from cooperation to rivalry.
What was once a cohesive Gulf coalition has given way to competing visions for regional influence, particularly after a series of clashes and political disputes over control of southern Yemen and the role of the UAE-backed Southern Transitional Council.
In late December, Saudi forces conducted airstrikes against positions linked to the Southern Transitional Council in Yemen’s Hadramaut and al-Mahrah governorates, prompting a stark warning from Riyadh that it would not tolerate threats to its national security.
Saudi authorities accused the UAE of supporting the separatist offensive near the Saudi border and issued an ultimatum for UAE-backed forces to withdraw from Yemen within twenty-four hours, underlining the Kingdom’s red-line posture toward external interference in its immediate neighbourhood.
Saudi officials labelled Abu Dhabi’s actions as “highly dangerous” and inconsistent with the original anti-Houthi coalition’s objectives.
This confrontation followed reports that Saudi-backed Yemeni government forces recaptured key territory, including Aden, and that the leader of the Southern Transitional Council had fled to the UAE, further straining bilateral ties.
The dispute in Yemen has exposed deeper strategic divergences between Riyadh and Abu Dhabi.
Saudi Arabia continues to emphasise the integrity of a unified Yemen and regional stability, while the UAE’s backing for separatist affiliates has been interpreted in Riyadh as a challenge to that vision.
Analysts view these developments as part of a broader shift in Saudi-UAE relations, where competition extends beyond Yemen to economic, political and security domains across the Red Sea and Horn of Africa.
The fracturing of what was once a tightly coordinated alliance in Yemen now plays out against the backdrop of wider geopolitical realignment, with each Gulf power pursuing distinct regional portfolios.
Saudi Arabia’s heightened military posture underscores its determination to spearhead a state-centred order in the Arabian Peninsula and protect its strategic interests along critical trade corridors linked to the Red Sea, even as tensions with its neighbour persist and evolve.
