The world's attention is turning to New York as presidents, prime ministers, diplomats and international organizations gather for the 81st session of the United Nations General Assembly, known as UNGA 81.
The 2026 General Debate officially runs from September 22 to September 26 and returns for a final day on September 28 at United Nations Headquarters in New York. The wider 81st General Assembly session opened earlier in September.
This year's theme is:
“Restoring trust, managing transformation: A United Nations that delivers for all.”
The theme reflects a central question facing the organization: how can international cooperation remain effective at a time of geopolitical rivalry, armed conflicts, rapid technological change and growing pressure on the global economy?
Here are some of the biggest issues likely to shape discussions during UNGA 81.
1. Wars, Security and the Search for Diplomatic Solutions
International security is once again at the center of the General Assembly.
Conflicts and tensions in the Middle East and Ukraine, along with their wider economic and humanitarian consequences, are among the major issues surrounding this year's high-level meetings.
UNGA is not a peace negotiation by itself, but the event creates something unusual: dozens of governments are present in the same city at the same time.
That means some of the most important developments can happen away from the main podium.
Bilateral meetings, closed-door discussions and meetings between foreign ministers can provide opportunities for governments to discuss ceasefires, humanitarian access, security arrangements and other diplomatic initiatives.
For readers following international affairs, therefore, the speeches inside the General Assembly Hall are only part of the story.
2. Artificial Intelligence Has Become a Global Political Issue
Artificial intelligence is no longer being discussed only by technology companies.
It has become a major subject of international diplomacy.
In his September 22 address, UN Secretary-General António Guterres called for stronger international oversight of AI risks and a multilateral framework for managing them.
Governments are increasingly debating questions such as:
Who should establish international AI standards?
How should powerful AI systems be monitored?
How can countries benefit from AI without widening economic inequality?
What rules should apply when AI is used in security and defence?
How should countries protect citizens from misuse of advanced technology?
These questions are particularly important because countries are adopting AI at very different speeds.
Some states have enormous computing resources and advanced technology industries, while many developing countries still face limited digital infrastructure.
The debate is therefore not just about AI safety. It is also about access, economic power and technological inequality.
3. Climate Change and the Energy Transition
Climate policy remains another major item on the UN agenda.
A dedicated High-level Event on Climate Action and the Just Transition is scheduled for September 23 during High-Level Week.
According to the United Nations, the meeting brings together major economies, vulnerable countries, developed and developing nations, as well as significant energy producers and consumers.
The debate has increasingly shifted beyond simply setting climate targets.
Governments now face practical questions:
Who pays for the transition?
How quickly should countries move away from fossil fuels?
How can developing economies finance clean infrastructure?
And how should countries prepare for extreme weather and other climate impacts that are already occurring?
For businesses and investors, these discussions can also matter because climate policies influence energy markets, infrastructure spending, transport and future regulation.
4. Reforming the United Nations
Another debate is about the UN itself.
The international system created after World War II looks very different from today's world.
Many governments have argued that institutions such as the UN Security Council should better reflect the political and economic weight of Africa, Asia and other regions.
But countries disagree strongly about how reform should work.
For example, Russia said on September 22 that it supports adding new permanent Security Council members while retaining the existing veto system. Turkish President Recep Tayyip Erdoğan has argued for more fundamental changes to the council's permanent membership and veto structure.
That illustrates the challenge.
There is significant discussion about reform, but much less agreement over what the final structure should look like.
5. Global Trade, Energy and Economic Uncertainty
Geopolitics and economics are becoming increasingly difficult to separate.
Wars can affect oil prices.
Trade restrictions can affect technology supply chains.
Political tensions can change investment decisions.
Energy disruptions can quickly increase transportation and food costs thousands of kilometres away.
Oil markets, for example, have remained sensitive to developments surrounding the Gulf and ongoing geopolitical tensions.
Consequently, conversations at UNGA increasingly touch on subjects that directly affect households and companies:
energy security, supply chains, inflation, food security, trade and economic resilience.
For developing economies in particular, fluctuations in fuel and food prices can have significant economic consequences.
6. The Growing Influence of the Global South
Another important story is the changing balance of international influence.
Countries across Africa, Asia, Latin America and the Middle East are increasingly seeking a stronger voice in global institutions.
Their priorities do not always match those of Washington, Brussels, Beijing or Moscow.
Issues including:
Development financing
Debt
Climate finance
Food security
Technology access
Trade
Representation in international institutions
are consequently becoming increasingly prominent in international discussions.
This makes UNGA especially significant.
Unlike smaller diplomatic groups, the General Assembly brings together virtually the entire UN membership, giving smaller countries a platform alongside the world's largest powers.
Why UNGA 81 Matters
The United Nations General Assembly does not have the power to solve every global crisis.
Many General Assembly resolutions are non-binding, and major geopolitical disagreements cannot be removed by a speech in New York.
But UNGA remains one of the world's most important diplomatic gatherings.
It allows governments to publicly set out their priorities while simultaneously holding hundreds of meetings behind the scenes.
The 2026 gathering is taking place while the international system faces pressure from armed conflicts, technological disruption, climate change and disagreements over how global institutions should operate.
That combination makes UNGA 81 worth watching well beyond the speeches themselves.
What Happens Next?
The General Debate continues through September 26, before concluding on September 28.
Over the coming days, attention will focus on major national speeches, bilateral meetings and any diplomatic announcements made on the sidelines.
SMONE will continue following the most important developments from UNGA 81 and explaining what they could mean internationally.
