UN General Assembly 2026: Can Global Diplomacy Turn Big Speeches Into Real Action?
The United Nations General Assembly is often described as the biggest stage in world diplomacy. That description is certainly justified. Nearly 130 heads of state and government are expected to attend the 81st session’s High-Level Week in New York. The General Debate begins on September 22.
But for me, the more important question is not who will speak at the UN podium.
It is this:
Will all those speeches translate into meaningful action?
That is where the real test lies.
The UN is still the world’s common meeting room
I have spent much of my professional life observing how organizations work. One lesson is simple: when people disagree, they still need a place where they can sit across the table.
The UN provides that table on a global scale.
Its 193 member states have an equal vote in the General Assembly. That does not mean every country has equal political or military influence. It does mean that almost every government has a formal place in the conversation.
At a time when wars are continuing in different regions, global trade is under pressure and countries are increasingly divided, having such a meeting place remains important.
The UN’s own theme for this year’s session says a lot: “Restoring Trust, Managing Transformation: A United Nations That Delivers for All.”
The words “delivers for all” are particularly important.
People around the world are becoming less interested in diplomatic language and more interested in results.
This year’s meeting comes at an unusually difficult moment
The General Assembly brings together countries dealing with wars, humanitarian crises, economic uncertainty, climate pressures and rapidly developing artificial intelligence.
The conflicts involving Ukraine and Russia and the Middle East will naturally dominate much of the diplomatic attention. Leaders will also use New York for private meetings that may be more consequential than their public speeches. Reuters reports that US President Donald Trump has a packed schedule of bilateral meetings during the gathering.
This is one reason I would not judge the UN only by what happens inside the General Assembly Hall.
Some of the most important diplomacy happens behind closed doors.
A meeting between two leaders may accomplish more than an hour-long speech watched by millions.
AI is another issue we should watch closely
One development particularly interests me: the growing role of artificial intelligence in international diplomacy.
AI is no longer just a technology story. It is becoming a question of national security, employment, misinformation, privacy and economic power.
UN Secretary-General António Guterres has been pushing for greater international cooperation on AI governance. The 81st General Assembly’s programme also includes digital governance and artificial intelligence as important priorities.
I believe this is an area where international cooperation could become increasingly important.
Technology does not stop at national borders.
A powerful AI system developed in one country can affect people in another country within seconds.
That makes global rules and responsible use increasingly difficult to avoid.
The UN’s credibility is also being tested
There is another side to this story.
The UN is facing criticism over whether it can actually stop wars or enforce the principles it promotes. Its financial difficulties have added another layer of pressure.
The United States recently made payments of $725 million toward its regular UN budget and another $102 million for peacekeeping, according to Reuters. The payments helped protect its voting rights while reducing its outstanding dues.
That tells us something important.
Even countries that strongly criticize the UN continue to engage with it because the institution remains useful.
But usefulness cannot be taken for granted.
The organization will have to demonstrate that reform can make it more efficient, financially responsible and capable of responding to modern crises.
A changing UN is inevitable
This General Assembly is also significant because António Guterres is approaching the end of his term as secretary-general.
The process of selecting his successor is already underway. Reuters reported on September 18 that Costa Rica’s former Vice President Rebeca Grynspan had emerged as the narrow frontrunner in an informal Security Council poll. That is only one stage of a process that ultimately requires agreement among the Security Council’s permanent members before the General Assembly appoints the nominee.
Whoever takes over will inherit a very different international environment from the one Guterres entered.
The next UN chief will need to deal with wars, geopolitical competition, AI, climate change, financial pressure and declining public trust.
My takeaway
The UN is neither a magic solution nor an irrelevant talking shop. It is what its member countries allow it to be.
If nations use it only for speeches and political theatre, its influence will continue to weaken.
If they use it for negotiation, humanitarian coordination, common rules and practical problem-solving, its importance will remain.
For ordinary people, the UN may seem distant from everyday life.
But decisions discussed in New York can eventually affect food prices, energy supplies, migration, security, technology, jobs and international trade.
That is why I will be watching this year’s General Assembly less for the applause and headlines — and more for one simple question:
What actually gets done after the speeches end?
