1. Context: Fragmentation of the Yemeni State

Yemen’s conflict has evolved from a binary civil war into a multi-layered contest involving state authorities, separatist movements, and regional powers. The recent fighting between the Saudi-backed Yemeni government and the Southern Transitional Council (STC) underlines the fragility of Yemen’s political settlement, especially in the south.

The STC’s surprise offensive in early December into Hadhramaut and al-Mahra, both oil-rich and strategically significant, exposed weak state control and unresolved grievances dating back to the former South Yemen. Although the STC briefly gained control of nearly half of the former South Yemen, its inability to hold territory highlighted its dependence on external backing rather than internal legitimacy.

Saudi-backed government forces, supported by Saudi air power, swiftly reversed the STC’s gains and re-entered Aden on January 7, forcing the STC leadership into negotiations. This sequence reaffirmed the Yemeni government’s military survival but not its political consolidation.

The persistence of parallel power centres reflects a governance vacuum; if unresolved, such fragmentation perpetuates cycles of rebellion and undermines any national reconstruction effort.

2. Issue: Regional Rivalries and Coalition Breakdown

The crisis brought latent tensions between Saudi Arabia and the UAE into the open, revealing fault lines within the Gulf-led coalition. While both states initially aligned against the Houthis, their strategic priorities in southern Yemen diverged over time.

Saudi Arabia, facing direct security threats from Houthi control near its borders, prioritised territorial stability under a recognised Yemeni government. The UAE, however, cultivated influence through support to the STC, seeing southern Yemen as a sphere for counterterrorism and maritime interests.

Riyadh’s accusation that Abu Dhabi transferred weapons to separatists, followed by Saudi air strikes on Mukalla port, marked a rare public rupture. The UAE’s subsequent announcement of troop withdrawal and an end to “counterterrorism operations” underscored the coalition’s erosion.

When external patrons pursue competing end-states, local actors are incentivised to defy central authority, prolonging instability rather than resolving conflict.

3. Implications: Strategic Gains for the Houthis

As government forces and the STC competed for influence in the south, the Houthis consolidated their hold over northern Yemen, including key population centres. The southern infighting indirectly strengthened the Houthis by diverting resources and political focus.

Saudi Arabia’s ceasefire with the Houthis reflected a pragmatic recalibration, prioritising border security over outright military victory. However, this further marginalised the Yemeni government’s authority and reduced pressure on Houthi entrenchment.

The result is a de facto divided Yemen, with fragmented governance structures and entrenched territorial control by non-state actors, complicating any future peace process.

Ignoring secondary conflicts within a civil war allows dominant armed groups to solidify control, making later political settlements costlier and more fragile.

4. Humanitarian and Development Consequences

The prolonged and layered conflict has produced one of the world’s gravest humanitarian crises. Millions of civilians remain on the brink of famine, while Yemen’s economy, infrastructure, and basic services lie in ruins.

Repeated shifts in control disrupt aid delivery, weaken institutions, and prevent coherent development planning. Civilian suffering is thus not merely collateral damage but a structural outcome of prolonged governance failure.

Without political stabilisation, humanitarian interventions remain palliative rather than transformative, unable to address root causes of vulnerability.

Development cannot proceed without minimal political order; continued conflict locks Yemen into a low-equilibrium trap of dependency and deprivation.

5. Way Forward: Federalism and Regional Coordination

For durable peace, Yemeni factions must converge on a federal governance structure that reflects current power realities while addressing historical southern grievances. Centralised restoration without accommodation risks renewed separatism.

Equally crucial is renewed coordination between Saudi Arabia and the UAE. As principal external stakeholders, their rivalry directly shapes local incentives and conflict trajectories.

Policy measures:

Inclusive federal negotiations involving government, southern actors, and Houthis
Joint Saudi-UAE commitment to a unified political roadmap
Gradual integration of armed groups into state institutions

Without external alignment and internal power-sharing, any peace arrangement will remain transactional and vulnerable to collapse.

Conclusion

The STC-government clash illustrates how Yemen’s conflict is sustained by both internal fragmentation and regional discord. Long-term stability depends on reconciling local governance demands with coordinated regional diplomacy, enabling Yemen to transition from conflict management to institutional recovery.

Quick Q&A

Everything you need to know

Historical and Political Context:
The conflict in southern Yemen stems from deep-rooted historical, political, and regional dynamics. After the Houthi seizure of Sanaa in 2014, the internationally recognised government retreated to Aden. The Southern Transitional Council (STC), a separatist entity backed by the UAE, challenged the government’s authority in the south, exploiting grievances from the former South Yemen state. The STC’s surprise offensive in December 2025 targeted oil-rich Hadhramaut and al-Mahra governorates, aiming to assert its dominance.

External Influences:
Saudi Arabia’s and the UAE’s diverging strategic priorities exacerbated the crisis. While Riyadh sought to stabilise southern Yemen under the government and counter Houthi threats along its border, Abu Dhabi supported the STC to safeguard its interests and extend influence in southern Yemen. This created a proxy contest between coalition partners, revealing fissures in the Gulf cooperation.

Immediate Triggers:
The flare-up was triggered by the STC’s attempt to expand territorial control, combined with alleged UAE weapons transfers, which Saudi Arabia perceived as a direct threat to its security strategy. Government forces, with Saudi air support, swiftly reclaimed lost territories, forcing STC negotiations in Riyadh and temporarily de-escalating hostilities.

Humanitarian Impact:
The ongoing conflict in Yemen has resulted in one of the world’s worst humanitarian crises. Millions of civilians face famine, disrupted livelihoods, and collapsed infrastructure. Prolonged fighting, including STC offensives and Houthi entrenchment, has devastated essential services such as healthcare, water supply, and education, leaving the population extremely vulnerable.

Regional Security Implications:
The conflict has wider repercussions for the Persian Gulf and Red Sea regions. Saudi-UAE tensions, diverging approaches to the STC, and the unresolved Houthi threat along Saudi borders have heightened insecurity. The UAE’s withdrawal and Saudi airstrikes on arms shipments in Mukalla illustrate how internal Yemeni disputes can escalate into inter-state disputes, threatening maritime security and regional trade routes.

Strategic Stakes:
Given Yemen’s location near the Bab el-Mandeb Strait, instability can disrupt global shipping and energy flows. Moreover, unchecked conflict creates fertile ground for extremist groups, complicating counterterrorism efforts. Hence, resolution of the southern flare-up is vital for both humanitarian relief and regional stability.

Coalition Divergence:
Initially, both Saudi Arabia and the UAE were part of the coalition supporting the Yemeni government against the Houthis. Over time, divergent interests emerged. Riyadh prioritised border security and stabilisation of the government in Aden, while Abu Dhabi sought to empower the STC to gain influence over southern ports and counter regional threats.

Escalation and Resolution:
The UAE’s alleged weapons transfers to the STC prompted Saudi airstrikes on Mukalla, exposing intra-coalition tensions. The conflict’s escalation forced STC leaders to send delegations to Riyadh, where negotiations led to the STC’s declared dissolution and the UAE’s withdrawal from operations. This sequence demonstrates how Gulf power competition shaped the conflict’s trajectory and its temporary resolution.

Implications for Regional Diplomacy:
The episode highlights the risks of coalition fragmentation. Divergent priorities can exacerbate local conflicts, complicate peace negotiations, and reduce the effectiveness of externally-backed interventions. Cooperative Gulf diplomacy is therefore essential for sustainable resolution.

Historical Fragmentation:
Yemen’s modern political history, particularly the existence of a separate South Yemen until 1990, has created entrenched regional and ideological divisions. These divisions underpin the STC’s separatist aspirations and the Houthis’ northern territorial ambitions.

Weak Central Authority:
The Yemeni government’s relocation to Aden and its reliance on external military support undermined its legitimacy and operational capacity. Weak governance allowed non-state actors like the STC and Houthis to expand their influence and consolidate territorial control.

External Patronage:
Foreign support has sustained armed factions. The UAE’s backing of the STC and Saudi Arabia’s support of the government exemplify how regional powers’ strategic interests prolong internal conflicts. Similarly, the Houthis’ resilience is bolstered by support from regional allies, making disarmament and political reconciliation extremely challenging.

Complex Power Dynamics:
Establishing a federal governance structure requires reconciling the interests of multiple factions—government, STC, Houthis, and tribal actors—each controlling different territories. Historical grievances and mistrust complicate consensus-building.

Regional and External Influences:
Saudi-UAE competition and external interventions influence internal negotiations. Any federal solution must accommodate the strategic interests of Gulf actors while safeguarding Yemeni sovereignty. The fluctuating involvement of foreign powers can undermine trust among local stakeholders.

Humanitarian and Institutional Constraints:
A devastated economy, fragile institutions, and a humanitarian crisis challenge effective governance. Building a functional federal system requires not only political agreements but also capacity-building for local administrations, legal frameworks, and inclusive power-sharing mechanisms. Without addressing structural vulnerabilities, federalism risks being nominal rather than transformative.

STC-Government Negotiations:
Past talks in Riyadh, including the recent January 2026 negotiations following the STC offensive, aimed at power-sharing and administrative integration. Although the STC announced its dissolution, representatives later dismissed these claims, highlighting limitations in enforcement and trust.

Saudi Military Interventions:
Saudi air power has periodically assisted the government in reclaiming territories from both Houthis and the STC. While militarily effective, these interventions often fail to address root political grievances, leading to cyclical violence.

Lessons Learned:
These examples underscore that military or negotiation measures alone are insufficient. Sustainable stability requires multi-faceted strategies, combining federal political structures, inclusive governance, regional coordination, and humanitarian reconstruction.

Proxy Dimensions:
The Yemen conflict exemplifies regional proxy competition between Gulf powers. Saudi Arabia’s focus on securing borders and stabilising the government contrasts with UAE support for the STC to maintain influence over strategic southern ports. Both powers pursue overlapping yet divergent interests, creating a multi-layered conflict landscape.

Consequences for Local Governance:
This proxy competition undermines Yemeni sovereignty, complicates reconciliation, and perpetuates humanitarian crises. The interplay of local factions with external patrons demonstrates how regional rivalries exacerbate internal fragmentation.

Global Lessons:
Yemen highlights the challenges of externally-backed conflict resolution in multi-faction environments. Proxy dynamics complicate peacebuilding, requiring coordination among regional powers and international actors. For policymakers, it underscores the importance of aligning local governance solutions with broader regional stability objectives to prevent repeated escalations.
