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.

Shibbir Ahmed | United Nations, New York — United Nations Secretary-General António Guterres has called for sweeping reforms to global institutions, arguing that the international system must adapt to a rapidly changing, increasingly multipolar world.

Addressing the Shanghai Cooperation Organization (SCO) summit in Bishkek on Tuesday, Guterres said global power relations were changing while many multilateral institutions continued to reflect the geopolitical realities of 1945.

“We must reform our multilateral institutions, including the United Nations and the Bretton Woods system, to reflect today’s realities,” Guterres said, calling for greater representation and influence for developing countries in order to build a fairer global order.

Guterres said the world was becoming increasingly multipolar and argued that the trend should be strengthened.

“Multipolarity is a condition for justice in global governance and international relations,” he said, describing it as a foundation for effective multilateralism and a United Nations that serves all countries without double standards.

The UN chief has repeatedly called for reforms to the Security Council and other international institutions to make them more representative of the current distribution of global power.

His remarks in Bishkek also highlighted four areas for stronger international cooperation: global security, development financing, climate action and governance of artificial intelligence.

Guterres’ call comes amid growing geopolitical tensions, conflicts and disputes over the effectiveness of existing international institutions. His message was clear: as global power shifts, the institutions governing international affairs must change with it.
