His Highness the Amir Sheikh Tamim bin Hamad al-Thani will address the opening of the 81st session of the UN General Assembly in New York today, leading Qatar's delegation as world leaders gather for the annual high-level debate.His Highness is expected to set out Doha's positions on regional and international issues, reaffirming Qatar's commitment to peace, security and international co-operation. The address is likely to underline Qatar's continued engagement in multilateral diplomacy, with particular emphasis on mediation as a central plank of its foreign policy in resolving conflict, alongside global challenges such as climate change, poverty and sustainable development.The Palestinian issue is expected to feature prominently in His Highness' remarks and in his talks with world leaders and senior UN officials, with Qatar reiterating calls for Palestinian rights to freedom, security and statehood, and renewing criticism of the international community's response to the continuing Israeli occupation and conflict.During the visit, HH the Amir is due to hold a series of bilateral meetings with heads of state, government leaders and senior international officials, with the talks intended to strengthen strategic partnerships and coordinate positions on issues before the General Assembly.The 81st session opened on September 8 under the theme "Restoring trust, managing transformation: a United Nations that delivers for all," with around 130 heads of state and government expected to take part in the general debate. President of the General Assembly and Foreign Minister of Bangladesh, Khalilur Rahman, opens proceedings and delivers the opening speech, after which Brazil traditionally takes the floor first as opening speaker, followed by the United States as host nation of UN headquarters. The speaking order for other member states is determined by level of representation, precedence and other criteria including geographic distribution.Most speeches at this year's session are expected to focus on restoring the credibility of the multilateral system, ongoing conflicts, institutional reform and climate issues, with heads of state, heads of government and ministers seeking solutions to interconnected global challenges in the pursuit of peace, security and sustainable development.Observers note that the meetings of the 81st session are taking place against a particularly complex international backdrop, overshadowed by protracted wars and humanitarian crises, climate instability, fears of new pandemics, a technology race driven by artificial intelligence, and mounting political and financial pressures on the international system.Beyond the leaders' speeches in the General Assembly Hall, this year's agenda spans a comprehensive programme of specialised meetings on development, climate, health, human rights and disarmament, though politics and security are set to dominate once the general debate begins. Foremost among these will be the conflicts in the Middle East and Ukraine, along with their implications for the future of the Palestinian cause.The Middle East is expected to feature prominently in leaders' addresses and in bilateral meetings, given persistent regional tensions and the ongoing Israeli attacks on the Gaza Strip and the West Bank. The Russia-Ukraine war will also remain a major focus, as the question of halting hostilities and the terms of any potential political settlement continue to divide the international community. The situation in Sudan is also expected to be addressed at the forum.Artificial intelligence is expected to emerge as a key new topic this year, amid growing calls for stricter regulation of its development following a series of incidents and warnings issued by prominent figures in the sector.This session carries added significance as the final General Assembly to open during the tenure of UN Secretary-General Antonio Guterres, whose second and final term concludes on December 31. The selection process for his successor, who is due to take office in early 2027 as the UN's tenth Secretary-General, is already under way, with behind-the-scenes consultations expected to continue through the session in pursuit of consensus on a candidate.In the lead-up to the high-level week, Guterres called on world leaders to honour their pledges, uphold the UN Charter, defend international law, protect human rights, invest in sustainable and inclusive development, and strive for peace. He said the world was entering a phase of "profound uncertainty," marked by shifts in the balance of power, rapid change and mounting threats requiring enhanced international co-operation, describing the United Nations as more than a platform — a "promise" that world leaders must fulfil.
