The 81st session of the United Nations General Assembly (UNGA) opened in New York on 22 September 2026 under the theme “Restoring trust, managing transformation: A United Nations that delivers for all”, as world leaders confronted overlapping crises from war in Ukraine and the Middle East to climate disruption and the governance of artificial intelligence.
Opening and Theme
UN Secretary-General António Guterres introduced his annual report and delivered what is expected to be his final address to the Assembly before the high-level general debate, which runs through 26 September and resumes on 28 September. The session’s presidency is held by UNGA President Khalilur Rahman, who formally opened the debate after Guterres. The UN’s official coverage frames the week as a test of multilateral cooperation amid “profound global uncertainty and transformation”, with agendas spanning conflicts, humanitarian emergencies, climate action, sustainable development and economic resilience.
Key Speeches and Flashpoints
Brazil’s President Luiz Inácio Lula da Silva spoke first, followed by US President Donald Trump, whose address dominated headlines. Trump told the Assembly he faced a “big decision” on Iran: either strike a deal after the US midterm elections or “annihilate the Islamic Republic”, language that drew sharp warnings from Tehran. Iranian state media reported that President Masoud Pezeshkian arrived in New York to attend, and US special envoy Steve Witkoff said Washington and Iranian delegations held “lengthy talks” through mediators on the sidelines.
France’s President Emmanuel Macron, in what was described as his last UNGA speech as French leader, defended the International Court of Justice after Trump called it “evil”, and called for a “double moratorium” on strikes against energy infrastructure and shipping in the Black Sea as the Russia–Ukraine war grinds into another winter. UK Prime Minister Andy Burnham, in his inaugural UNGA address, pledged that Britain would lead global work on AI standards and announced a new AI defence partnership with the US, while warning that the technology is a “multiplier of risk” that must be governed by elected governments.
Ukrainian President Volodymyr Zelensky described his meeting with Trump as “positive and productive”, saying they discussed “potential de-escalatory steps” and a possible “energy ceasefire” with Russia; he added he was ready for a trilateral meeting with Moscow and Washington to end the war. On the Middle East, Qatar’s Emir Sheikh Tamim and Türkiye’s President Recep Tayyip Erdogan used their speeches to condemn Israeli actions in Gaza and the occupied West Bank, with the Emir describing Gaza as having suffered a “genocide in every sense of the word”.
Sideline Diplomacy and Announcements
Several significant bilateral and multilateral moves unfolded alongside the speeches. Canada’s Prime Minister Mark Carney announced about US$71 million in assistance for the Palestinian government and new restrictions on goods from Israeli settlements, calling the steps a pragmatic effort to preserve the possibility of a two-state solution. Japan’s Prime Minister Sanae Takaichi pressed for the return of Japanese citizens abducted by North Korea decades ago, calling it an “ongoing matter with lives at stake”. South Korea’s President Lee Jae Myung set out principles for “peaceful coexistence” with the North, including re-establishing basic communications and working toward a formal end to the Korean War.
Venezuela’s acting President Delcy Rodríguez held her first meeting with Trump since the US operation that captured former President Nicolás Maduro, who remains in detention in Brooklyn; Rodríguez hailed the encounter as “historic” and focused on energy, mining and security cooperation. At the same time, opposition leader María Corina Machado was denied entry to Venezuela multiple times this week, her adviser told CNN, underscoring the country’s fragile political transition.
New York deployed thousands of NYPD officers around UN headquarters for the high-level week, with elevated but “standard” security posture and no known specific threats, according to city officials. The General Assembly’s opening also came as the UN endorsed a separate resolution encouraging countries to adopt the Equal Earth world map projection, a symbolic but widely noted move to correct geographic distortions in the traditional Mercator map.
