UAE-backed Separatists Set Two-year Path to South Arabia Referendum

The UAE-backed Southern Transitional Council announced a two-year transition plan on Jan. 3 that would culminate in a referendum on southern independence "within two years," and unveiled a provisional 30-article constitution for a proposed state it calls the "State of South Arabia." The declaration follows a surprise offensive in late 2025 in which the STC seized additional territory in southern and eastern Yemen, setting off renewed fighting, retaliatory air strikes and diplomatic strain among Gulf backers of the government in Sanaa.

The offensive last month expanded the STC's control beyond its established strongholds, including reported advances into resource-rich Hadramawt province on Yemen's eastern flank. Observers say control of Hadramawt opens a potential corridor for rerouting hydrocarbon exports away from the Strait of Hormuz, a strategic shift that would reverberate through regional energy and maritime security calculations. Government forces, backed by Saudi-led coalition operations, later swept into parts of the newly seized areas and retook some strategically important terrain, underscoring that the battlefield remains highly fluid.

Military escalation has accompanied the political announcement. Saudi-led coalition air strikes and ground operations have targeted STC positions in recent days, and separatist sources report roughly 20 deaths from coalition strikes. STC commanders reported multiple strikes on military camps and infrastructure, including an airport, as forces vied for control of desert and coastal approaches. The STC said the transition would include dialogue with the Iran-backed Houthi movement in the north but warned that independence would be declared "immediately" if dialogue was refused or if STC forces came under attack again.

The crisis has exposed a serious rift between Abu Dhabi and Riyadh over strategy in Yemen. The United Arab Emirates voiced it was "deeply concerned" about the escalation and said it had withdrawn its remaining forces from Yemen after a coalition strike on a UAE shipment at Mukalla port earlier in the week. Saudi authorities moved to temper tensions, inviting southern factions to Riyadh "to discuss just solutions to the southern cause," and Yemen's Saudi-backed Presidential Council requested that Saudi Arabia host a forum aimed at including all southern factions "without distinction." The diplomatic effort seeks to prevent the conflict from fracturing the broader anti-Houthi coalition and to contain the risk of state fragmentation.

On the ground, imagery and public rallies show visible local support for the STC in parts of the south, where flags from the former People’s Democratic Republic of Yemen and portraits of STC leaders have reappeared in Aden and tribal centers. That symbolism underscores deep historical grievances dating to the 1967–1990 division of north and south Yemen and gives the separatist project domestic resonance that military reversals alone may not extinguish.

International law offers no simple template for unilateral secession; recognition by states and the ability to govern territory effectively will determine whether the STC’s political timetable can translate into a viable state. For regional actors, the choice between backing a unified Yemen or acquiescing to a southern state carries strategic trade-offs that include control of energy corridors, counterterrorism cooperation and the stability of Gulf diplomatic alignments. As the two-year window opens, Yemen faces a heightened risk of formal partition at a time when humanitarian needs and armed fragmentation remain acute.
