Shibbir Ahmed, New York — UN Secretary-General António Guterres has warned that the world is entering an “era of deep uncertainty,” urging governments to strengthen international cooperation as leaders prepare to gather in New York for the 81st UN General Assembly.

Speaking ahead of the General Assembly’s high-level week, Guterres identified rapidly advancing artificial intelligence, the climate crisis and deepening inequalities as major existential threats facing the international community.

Guterres devoted much of his remarks to the growing risks associated with artificial intelligence. While acknowledging AI’s potential to accelerate development, improve education and health systems and strengthen climate resilience, he warned that technological development is advancing faster than the world’s understanding of its risks.

He called for stronger safeguards to make AI development safe, transparent and accountable, with human dignity at the centre. Guterres said national action is important but stressed that global coordination is essential because AI and its risks do not stop at national borders.

The UN chief also urged world leaders to address ongoing conflicts. He reiterated his call for a ceasefire in the Russia-Ukraine war and urged implementation of a two-state solution in the Middle East. He also called for de-escalation and the protection of civilians.

The General Assembly’s high-level week begins in New York on September 18, with the General Debate scheduled to begin on September 22. Leaders from all 193 UN member states are expected to address global challenges, including conflicts, climate change, international security and sustainable development. Guterres said international cooperation is more necessary than ever as governments confront interconnected global crises.

Shibbir Ahmed, UN, NEW YORK — The 81st session of the United Nations General Assembly officially opens Tuesday in New York, bringing together the world’s nations at a time of intensifying conflicts, humanitarian crises, economic uncertainty and growing pressure on the multilateral system. The ordinary session will run from September 8, 2026, through September 7, 2027, according to the United Nations. Bangladesh’s Khalilur Rahman is serving as president of the 81st General Assembly session.

The theme of this year’s session is “Restoring Trust, Managing Transformation: A United Nations That Delivers for All.” The theme reflects growing international concern over the ability of multilateral institutions to respond effectively to war, humanitarian emergencies, climate change, inequality and rapid technological change.

The opening of the session comes as the international community faces multiple major crises, including ongoing armed conflicts and humanitarian emergencies. The General Assembly is expected to provide a major diplomatic forum for member states to discuss peace and security, sustainable development, human rights and international cooperation.

Khalilur Rahman, who was elected president of the 81st session in June, has outlined six major priorities for his presidency: peace and security, sustainable development, climate resilience, human rights and humanitarian protection, inclusive innovation and renewed multilateralism.

His vision also places emphasis on strengthening the United Nations’ ability to deliver practical results and rebuilding confidence in the multilateral system. The opening session is only the beginning of an intense period of diplomacy at UN Headquarters. The General Assembly’s high-level general debate is scheduled for later in September, when heads of state and government from around the world are expected to gather in New York.

The United Nations says the 81st session will also address major issues including peace and security, sustainable development, climate action, human rights, artificial intelligence and reform of the UN system. With the world facing deep geopolitical divisions, the 81st General Assembly is set to test whether nations can rebuild trust and find common ground through multilateral diplomacy.
