Minurso mandate suspended after US and Russia exchange vetoes

The United Nations mission in Western Sahara currently lacks a mandate following a rare exchange of vetoes between the United States and Russia.

The standoff prevented the Security Council from extending the mission's authority for another year. Both permanent members blocked the other's proposed resolution during October 2026 sessions.

The dispute centers on the legal status of the territory and the role of Morocco's autonomy plan in future negotiations. The US sought to entrench this plan as the sole basis for talks. Russia argued that the council should not prejudge sovereignty before a final agreement is reached.

In 2025, the Security Council endorsed Morocco's autonomy proposal as a foundation for resolving the conflict. The council also requested that UN Secretary-General Antonio Guterres review the mission's structure. This shift set the stage for the current disagreement over how to formalize those changes.

The US drafted a resolution to rename the mission. It would have removed the word "referendum" from the name, changing it from the United Nations Mission for the Referendum in Western Sahara to the United Nations Mission in Western Sahara. The draft also proposed reducing the military component and extending the mandate for 12 months.

Russia vetoed the US text, arguing that the council was adopting a one-sided approach. Ambassador Vassily Nebenzia stated that the council cannot automatically pre-determine matters relating to sovereignty. He said the council must not give a blessing to such an approach, compelling his delegation to block the draft.

In response, the United States vetoed a Russian-drafted resolution. That text would have extended the mission's mandate for another year without altering its existing terms or name. Eleven members of the council voted against the Russian draft.

Ambassador Michael Waltz said that longstanding disagreements over voter eligibility have prevented the UN from holding a referendum. He noted that UN officials have communicated this reality for 30 years. Waltz criticized the retention of the letter "R" in the mission's name, arguing that the UN has not prepared to hold such a vote for decades.

The mission currently includes 155 military personnel. It was established to organize a referendum under a UN-brokered ceasefire. A report by the UN secretary-general estimated the mission's cost at $62 million for the financial year beginning in June 2026.

Oxfam warned that losing the mission could undermine security and stability. The organization stated that the loss of monitoring and de-escalation functions risks serious consequences for civilians. Most Sahrawis live in the part of Western Sahara under Moroccan control, while tens of thousands reside in refugee camps in Algeria. The rejected US resolution would have called on the UN refugee agency to conduct a census of those refugees.
