- US and Iranian officials reopened indirect diplomatic channels, while Ukraine and Russia explored limited ceasefires for energy and grain infrastructure.
- Venezuela discussed debt restructuring and economic ties with the US, though political transition and election timelines remain unsettled.
- Tensions over AI safety and regulation emerged, reflecting a broader geopolitical competition for technological dominance between major global powers.
- The General Assembly concluded with warnings from António Guterres about the UN’s limited ability to resolve conflicts amidst deep international divisions.
NEW YORK: A week of high-level diplomacy at the 81st United Nations General Assembly ended Friday without major breakthroughs. But behind the speeches and meetings, governments were testing whether smaller agreements could still be reached on some of the world's most difficult disputes.
The wars involving Iran and Ukraine remained unresolved. Venezuela's political crisis was still unsettled, and the war in Sudan continued. Yet there were signs of movement on narrower issues, including Iran, Ukraine and Venezuela's economic future.
The week also exposed a deeper problem facing the United Nations. Major powers remain divided over how conflicts should be handled, how much authority international institutions should have and who should set the rules for fast-moving technologies such as artificial intelligence.
New York once again provided a place for governments to talk when they could not agree. It also showed just how limited those talks can be.
Iran and the US reopen a channel
The most closely watched diplomacy involved Iran and the United States.
Iranian Foreign Minister Abbas Araghchi and US special envoys Steve Witkoff and Jared Kushner held indirect discussions through intermediaries. The contact came after months of conflict and an unstable ceasefire between the two countries.
There was no agreement.
What mattered was that Washington and Tehran were still talking. After months of confrontation, the two sides were at least testing whether diplomacy could offer a way out.
Their public positions remained far apart.
President Donald Trump warned Iran of severe military consequences if it failed to reach an agreement with Washington. Iranian President Masoud Pezeshkian, speaking at the General Assembly, said Iran would not surrender but remained committed to diplomacy. Reuters reported that Pezeshkian spoke a day after Trump warned that the United States could “annihilate” Iran.
The main disputes remain familiar: Iran's nuclear programme, sanctions, shipping through the Strait of Hormuz and the terms of any longer-term ceasefire.
Iran wants relief from economic restrictions and recognition of its right to civilian nuclear activity. Washington is seeking wider commitments from Tehran.
For now, the gap is wide.
But talks matter because there can be no negotiation without communication. The question is whether the contacts in New York lead to a more organised diplomatic process.
There is also reason for caution. Both countries have previously negotiated while maintaining military and economic pressure on each other. Opening a channel may reduce the risk of miscalculation without bringing the sides much closer to a settlement.
For now, the New York contact looks more like an opening than a breakthrough.
Ukraine: smaller deals before a wider settlement
A similar pattern emerged in discussions over Ukraine.
US Secretary of State Marco Rubio met Russian Foreign Minister Sergei Lavrov in New York. Afterward, Rubio said Russia and Ukraine had shown interest in a limited ceasefire covering grain shipments and energy infrastructure.
Ukrainian President Volodymyr Zelenskyy had separately said Kyiv was prepared to discuss a ceasefire covering energy infrastructure and a maritime arrangement in the Black Sea. Reuters reported that Zelenskyy said Ukraine was ready for a maritime truce based on proposals involving Egypt, India and Turkey.
These proposals are far narrower than a peace agreement.
The central disputes — territory, security guarantees and the future relationship between Russia and Ukraine — remain unresolved. An arrangement covering power plants or shipping would not settle those questions.
It could, however, reduce some of the immediate damage caused by the war.
Ukraine is heading into another winter in which attacks on power and heating infrastructure could put civilians under further pressure. An agreement on Black Sea shipping could also help protect agricultural exports.
Russia has not publicly endorsed the ceasefire proposals in the terms described by Rubio. Before his meeting with Lavrov, Kremlin spokesman Dmitry Peskov said there were still no conditions for moving toward peace negotiations, although Russia remained open to talks.
That difference matters.
The discussions are still exploratory. There may be room for agreement on individual issues, but that should not be mistaken for progress toward ending the war.
AI moves deeper into the UN agenda
Artificial intelligence was another major subject in New York.
AI did not replace climate change, war, development or inequality as the central issues at the General Assembly. But it received unusually high-level attention, including at the Security Council.
OpenAI chief executive Sam Altman was scheduled to brief the Security Council on the security implications of AI. The discussion focused on international cooperation and common safety standards as AI systems become more capable.
Governments are increasingly divided over how the technology should be managed.
Some governments and technology leaders argue that international rules are needed because AI could be used in cyber operations, military systems and critical infrastructure. The UN's independent scientific panel on AI has also called for safeguards as governments try to understand the risks.
The Trump administration has taken a different position. In his General Assembly speech, Trump dismissed many concerns about AI safety and argued for continued US leadership in the technology. Reuters reported that he framed the issue partly as a competition over advanced “super intelligence.”
The dispute is about more than safety.
AI has become part of the wider competition among the United States, China and other technology powers. Governments are competing for computing capacity, investment, talent and control over advanced systems.
Developing countries have a different concern: whether the rules governing AI will be written mainly by countries and companies that already dominate the technology.
That makes AI a difficult issue for the UN. Governments broadly agree that the technology is moving quickly. They are much less united on who should regulate it and how far international rules should go.
Venezuela looks for economic room
Venezuela's interim President Delcy Rodriguez was another important figure in New York.
Rodriguez met Trump on the sidelines of the General Assembly, their first meeting since US forces captured former Venezuelan President Nicolás Maduro in January. Reuters reported that they discussed Venezuela's debt and economic future.
A Venezuelan delegation also held talks with US officials and international financial institutions about debt restructuring, energy and mining. Reuters reported that Venezuela's debt, including obligations linked to state oil company PDVSA, could total roughly $150 billion to $200 billion.
For Caracas, access to financing and foreign investment is an urgent economic need.
For Washington, Venezuela's oil resources and political transition are important issues.
The political question, however, remains unresolved.
Rodriguez told the UN that Venezuela would hold elections as part of a transition toward what she described as full democracy. She did not give a date. Reuters reported that US officials said Trump pressed her on political change and free and fair elections during their meeting.
That leaves a gap between the economic discussions and the political transition.
The Venezuelan government wants access to international finance and investment. The United States has an interest in Venezuela's energy sector and political transition. Opposition groups continue to seek clear guarantees about elections.
The meetings produced contacts and negotiations, but no final agreement on Venezuela's political future. Reuters reported that no major concrete deals had emerged and that there was still no firm election date.
Sudan shows the limits of pressure
The absence of Sudanese army chief Abdel Fattah al-Burhan also became an important issue during the UN week.
The United States withheld a visa for Burhan ahead of his planned appearance at the General Assembly. Reuters, citing sources and a letter from Sudan's UN ambassador, reported that the visa issue appeared to be linked to a US-backed 90-day ceasefire proposal that Sudan's army had reservations about.
The episode highlighted a basic tension within the UN.
The organisation is supposed to provide a place where governments can meet even when they are fighting. But its headquarters are in the United States, and access to the country is ultimately subject to US immigration decisions.
Washington's position is part of its broader effort to pressure the parties involved in Sudan's war.
Sudan's military has resisted some outside mediation efforts and has argued that ceasefires can benefit the Rapid Support Forces.
The war began in April 2023, when fighting broke out between the Sudanese Armed Forces and the RSF. It has since caused mass displacement and a severe humanitarian crisis.
The dispute over Burhan's visa did not change the course of the war. But it showed how difficult it can be to separate the UN's role as a diplomatic forum from the foreign-policy interests of powerful member states.
Guterres leaves a UN under pressure
The General Assembly also marked the final high-level session for António Guterres as UN secretary-general.
In his final address, Guterres warned that the world's major powers could not solve global problems on their own. He called for stronger international cooperation and changes to institutions that, in his view, no longer reflect the distribution of power in the world.
He leaves at a difficult moment for the organisation.
The UN is dealing with wars in several regions, financial pressure, humanitarian emergencies and growing tensions among major powers. The United States has reduced support for parts of the UN system and challenged the role of several international institutions.
But criticism of the UN is not limited to Washington.
Many developing countries have long argued that the Security Council does not reflect today's world. Africa, in particular, has no permanent seat despite its large UN membership and the number of conflicts on the organisation's agenda.
Guterres again called for Security Council reform, including permanent African representation.
The problem is that any major reform requires agreement from the countries whose existing privileges could be affected.
That is one of the UN's central dilemmas. Governments broadly agree that reform is needed. They remain divided over what that reform should look like.
The next secretary-general inherits the same problem
The process of selecting Guterres' successor is already underway.
The UN's official list includes six candidates: Rafael Mariano Grossi of Argentina, Rebeca Grynspan of Costa Rica, Olara Otunnu of Uganda, Carolyn Rodrigues Birkett of Guyana, Macky Sall of Burundi's nomination and María Fernanda Espinosa Garcés.
The selection involves consultations among member states, the General Assembly and the Security Council. Candidates have also taken part in public interactive dialogues where they present their views and answer questions from governments and civil society.
The final decision will depend heavily on negotiations among member states, particularly the permanent members of the Security Council.
So the process is not only about individual candidates. It also reflects what governments want from the UN at a time of growing geopolitical competition.
The next secretary-general will inherit the same basic problem that confronted Guterres: the UN can provide a place for diplomacy, but its ability to act depends heavily on whether its most powerful members are willing to cooperate.
What the week revealed
The main story from this year's General Assembly was not that diplomacy had stopped working. It was that diplomacy is increasingly being pursued in smaller pieces.
The US and Iran reopened a channel without resolving their main disputes.
Russia and Ukraine showed some interest, according to US officials, in limited arrangements involving energy and food, while remaining far apart on the larger questions of the war.
Venezuela opened discussions on debt, energy and political transition, but the timing of elections remained unclear.
Sudan showed how difficult it is to bring opposing sides into the same diplomatic process when outside powers disagree over how much pressure should be applied.
And AI showed that the UN's agenda is moving beyond traditional questions of war and peace toward technology, security and global regulation.
None of this amounts to a new international settlement.
But it does show where diplomacy is still possible: limited agreements, temporary arrangements and keeping communication channels open.
The larger disputes remain.
Iran and the United States still disagree over the terms of any lasting settlement. Russia and Ukraine remain divided over the central issues of the war. Venezuela still has to show how its promised political transition will work. Sudan's war continues despite repeated diplomatic efforts.
The UN can bring these disputes into one building. It cannot settle them on its own.
That is both its strength and its limitation.
The organisation remains one of the few places where almost every government can meet. But what it can accomplish depends on whether those governments — especially the major powers — are prepared to compromise.
That is the challenge the next secretary-general will inherit when Guterres leaves office at the end of December.
The question for the UN is no longer simply whether it can remain relevant. It is whether its member states can still find enough common ground to make it work when the problems before them are becoming harder to resolve.
