The UN General Assembly 2026 opens its most closely watched high-level week on September 22, bringing world leaders and senior officials to New York amid wars, diplomatic tensions, technological challenges and questions about the future role of the United Nations.
The 81st session’s General Debate will run from September 22 to 26 and September 28, according to the United Nations. The official theme is “Restoring trust, managing transformation: a United Nations that delivers for all.”
The General Assembly represents all 193 UN Member States, with each country holding one vote. Alongside speeches in the General Assembly Hall, much of the diplomatic activity takes place through bilateral meetings, smaller groups and negotiations on the sidelines.
This year’s gathering is particularly significant because the agenda extends well beyond the formal speeches. The Iran conflict, Ukraine, Gaza, artificial intelligence and the upcoming transition to a new UN secretary-general are among the issues attracting attention.
Here are eight major issues to watch during UN General Assembly 2026.

1. Trump’s Meetings With Gulf Leaders and the Iran War
The Iran conflict is expected to be one of the central diplomatic issues surrounding UN General Assembly 2026.
US President Donald Trump is scheduled to address the General Assembly on September 22 and is also expected to meet leaders from the Gulf Cooperation Council. Reuters reported that discussions with Gulf leaders are expected to focus on Iran and Washington’s approach to the conflict.
The GCC includes the United Arab Emirates, Saudi Arabia, Qatar, Kuwait, Bahrain and Oman.
The regional discussions come as the conflict continues to affect security, energy markets and shipping routes. Recent Houthi activity has added further pressure around the Red Sea and Gulf region, while developments involving the Strait of Hormuz remain closely watched.
Trump has said he hopes the conflict may be approaching an end, while Washington and Tehran continue to have sharply different positions over the future of Iran’s nuclear programme and the wider conflict.
For Gulf countries, the meetings also provide an opportunity to discuss regional security and the potential consequences for trade, energy and transport.
2. Could Trump and Pezeshkian Meet?
One of the most closely watched possibilities at UN General Assembly 2026 is a potential meeting between Trump and Iranian President Masoud Pezeshkian.
The United States has approved visas for Pezeshkian and Iranian Foreign Minister Abbas Araqchi to attend the UN high-level meetings. The Iranian delegation will face restrictions on movement in New York.
Trump has indicated that he would be open to meeting Pezeshkian, although no confirmed presidential meeting had been announced at the time of the latest reports.
The possibility is significant because the two governments remain in conflict while diplomatic contacts have continued intermittently.
Any meeting, if it occurs, would therefore be watched for indications about whether direct diplomacy could play a larger role in the next phase of the conflict.
At the same time, the presence of both delegations does not itself indicate that an agreement is imminent. Their positions remain substantially different, and the outcome of any diplomatic contacts remains uncertain.
3. Will UNGA Create Space for an Iran Deal?
Beyond a possible Trump-Pezeshkian meeting, diplomats will be watching whether UN General Assembly 2026 creates opportunities for broader negotiations.
The United States and Iran have maintained intermittent diplomatic contacts despite the conflict, according to recent reporting. The arrival of senior Iranian officials in New York creates opportunities for meetings involving intermediaries and other governments.
The UN General Assembly can provide a particularly unusual diplomatic environment because leaders who rarely meet in their home countries can be present in the same city at the same time.
However, the General Assembly itself does not automatically produce a negotiated settlement. Any progress would depend on the positions of the governments involved and the willingness of the parties to pursue negotiations.
For markets and regional governments, developments around the Iran conflict could also have consequences for energy prices and shipping.
Reuters reported that oil prices have recently reacted to expectations surrounding possible US-Iran diplomacy and developments affecting Saudi oil exports.
4. What Will Trump Say From the UN Podium?
Trump’s General Assembly address will be another major moment.
Reuters reported that his speech is expected to focus on his administration’s foreign-policy approach and Washington’s position that Iran must not obtain a nuclear weapon.
The address will also come against the background of Trump’s complicated relationship with the United Nations.
The broader UN General Assembly 2026 agenda, however, extends far beyond US foreign policy. Leaders are expected to address conflicts, development, climate issues, technology and international cooperation during the high-level week.
The official UN programme includes separate high-level meetings on climate action, sea-level rise, pandemic preparedness and the implementation of development commitments.
5. Can Diplomacy Move the Ukraine War Forward?
Ukraine will remain another major issue during UN General Assembly 2026.
Ukrainian President Volodymyr Zelensky has said he and Trump have agreed to meet in New York. Reuters reported that their discussions are expected to take place during the General Assembly gathering as diplomatic contacts continue over the war with Russia.
The meeting comes after recent contacts involving US and Ukrainian officials and continuing efforts to explore a route toward ending the conflict.
Russia will also have a senior diplomatic presence. Reuters reported that Russian Foreign Minister Sergey Lavrov is expected to participate in the General Assembly gathering, while other reports have highlighted the continuing diplomatic divide between Moscow, Kyiv and Washington.
The central questions include the conditions for negotiations, security arrangements and the future of Ukraine’s territory and sovereignty.
Rather than expecting a single UN speech to resolve those questions, observers will be watching the bilateral meetings around the Assembly for signs of diplomatic movement.
6. Gaza and Palestinian Statehood Remain Central
The Israeli-Palestinian conflict will also occupy a prominent place during UN General Assembly 2026.
The issue of Palestinian statehood and the two-state solution remains a major part of international diplomacy, while the humanitarian situation in Gaza continues to shape discussions at the UN.
Palestinian Authority President Mahmoud Abbas is expected to participate remotely after the United States denied him a visa, according to recent reporting. The issue has already generated controversy because Palestine’s participation at the UN has been a recurring diplomatic subject.
The General Assembly has previously adopted measures allowing Palestinian representatives to participate virtually when visa restrictions prevented attendance in New York.
The wider debate will include the future of the two-state solution and the role of international diplomacy in addressing the conflict.
France is also expected to convene discussions related to the two-state solution during the General Assembly period, according to the source material surrounding this year’s meeting.
7. Artificial Intelligence Moves Higher on the UN Agenda
Artificial intelligence has become another major subject at UN General Assembly 2026.
The technology is no longer being discussed only as an economic or innovation issue. Governments and international organisations are increasingly examining AI in relation to security, misinformation, regulation, human rights and governance.
The UN has placed AI among the major challenges requiring international cooperation. The 2026 high-level week includes discussions focused on technology and human development, while the Security Council is also expected to address AI-related issues during the gathering.
Secretary-General António Guterres has also made AI governance a major part of his international agenda.
For businesses and technology users, the debate could have long-term implications because international discussions are increasingly focused on how governments can encourage AI development while addressing risks.

The UN’s AI discussions are expected to focus on governance rather than simply promoting or opposing the technology.
8. Who Will Become the Next UN Secretary-General?
Behind the immediate crises, UN General Assembly 2026 is also taking place during an important leadership transition.
António Guterres’ second term ends on December 31, 2026, meaning the organisation will begin 2027 with a new secretary-general. The formal selection process is already underway.
The UN says the secretary-general is appointed by the General Assembly following a recommendation from the Security Council. The current selection process includes candidate nominations, public vision statements and interactive dialogues with Member States and civil society.
The published candidate field has included diplomats and senior international figures from different regions. The UN has made information about nominations, CVs, vision statements and campaign-financing disclosures publicly available as part of the process.
The next secretary-general will inherit an organisation dealing with multiple conflicts, financial pressures, technological change and debates over the future of multilateral institutions.
That makes the leadership transition one of the important institutional stories surrounding this year’s Assembly.
Why UN General Assembly 2026 Matters Beyond New York
The significance of UN General Assembly 2026 extends beyond the speeches delivered inside the General Assembly Hall.
The 81st session brings together 193 Member States, while high-level meetings and bilateral discussions provide opportunities for governments to discuss issues ranging from war and security to climate, health and technology.
The official programme includes several additional high-level meetings during the week:
- September 23: Climate action and the just transition
- September 24: Sea-level rise
- September 25: Pandemic prevention, preparedness and response
- September 28: Durban Declaration and Programme of Action
- September 29: International Day for the Total Elimination of Nuclear Weapons
These issues show that the General Assembly agenda is broader than the major wars dominating headlines.
The challenge for diplomats is that these subjects are interconnected. Conflicts can affect energy markets and food security, technology can influence security and information systems, and climate pressures can create additional economic and humanitarian challenges.
What to Watch as the Week Unfolds
The most important developments during UN General Assembly 2026 may come from meetings happening outside the main chamber.
For the Middle East, attention will centre on US-Iran diplomacy, Gulf security and developments affecting shipping and energy.
For Ukraine, meetings involving Trump, Zelensky and other governments could provide information about the direction of ongoing diplomatic efforts.
For Gaza, discussions over Palestinian statehood and the two-state solution will remain prominent.
For the UN itself, AI governance and the selection of a new secretary-general represent longer-term institutional questions.
The official UN theme of “Restoring trust, managing transformation” reflects this broader agenda.
Whether the gathering produces concrete agreements on any individual crisis will depend on negotiations among the governments involved. But the concentration of world leaders in New York makes the week an important forum for diplomacy, public statements and behind-the-scenes discussions.
Final Thoughts
The UN General Assembly 2026 is taking place at a moment when several international crises are unfolding simultaneously.
Trump’s meetings on Iran, the possible contact between Washington and Tehran, Ukraine diplomacy, Gaza and Palestinian statehood, AI governance and the transition to a new UN secretary-general are among the issues likely to receive significant attention.
The Assembly’s formal debate runs from September 22 through September 26 and resumes on September 28, while high-level meetings and diplomatic engagements continue around the schedule.
The coming days will therefore provide a concentrated view of how governments are approaching some of the world’s most pressing security, humanitarian, technological and institutional challenges.
