World leaders are converging on New York for the high-level week of the 81st session of the United Nations General Assembly, with the general debate running from September 22 to 26. The session’s theme — “Restoring Trust, Managing Transformation: A United Nations That Delivers for All” — captures the organisation’s central challenge: proving its relevance at a moment of overlapping wars, economic shocks and deep cuts to development funding.
Key takeaways
- The 81st session is presided over by Khalilur Rahman, a veteran diplomat with more than four decades of experience.
- Official development assistance fell 23.1% in real terms in 2025, the largest annual drop on record.
- The race to succeed Secretary-General António Guterres, whose term ends on December 31, is underway.
A crowded agenda
Beyond the leaders’ speeches, the week is packed with high-level meetings. Sessions are dedicated to climate action and a just transition, sea-level rise affecting small island states and low-lying coasts, and pandemic prevention following the adoption of the WHO Pandemic Agreement. A commemoration of the 25th anniversary of the Durban Declaration against racism follows on September 28.
Development goals off track
The UN’s own 2026 assessment makes for sobering reading: only 36% of 139 measurable Sustainable Development Goal targets are on track or moderately progressing, 49% show marginal progress and 15% have regressed below their 2015 baseline. With aid budgets shrinking in many donor countries and the OECD projecting further cuts in 2026, developing nations are expected to press hard for debt relief and new financing.
UN80 and the push for reform
The UN80 Initiative, launched to streamline mandates and improve efficiency, is moving from review to implementation. Supporters say consolidation is essential to protect core humanitarian work at a time of tight budgets; critics warn that cuts could weaken agencies just as needs grow.
The question hanging over the General Assembly this year is not whether the world needs multilateral cooperation, but whether the UN can deliver it with less money and less consensus.
Conflicts in the background
The general debate takes place against the backdrop of the war involving Iran and the resulting disruption to shipping in the Strait of Hormuz, continued fighting in Ukraine, the war in Sudan and rising tensions in the Horn of Africa. Many speeches are expected to focus on humanitarian access, food security and energy prices.
What to watch this week
- Statements from major powers on Gulf shipping and humanitarian corridors.
- Signals on candidates for the next Secretary-General.
- Pledges, if any, to reverse the slide in development finance.
