UN General Assembly President Annalena Baerbock on Monday officially closed the high-level week of the 80th session, urging nations to turn the momentum of the debate into tangible action on peace, climate change, and institutional reform.
She reaffirmed the role of the United Nations as “the house of diplomacy and dialogue” in a divided world.
Over six days of discussions, from September 23 to 29, representatives of 189 Member States addressed the Assembly, including 124 heads of state and government. Secretary-General António Guterres also met bilaterally with about 150 world leaders, according to his office.
Baerbock emphasized the seriousness of today’s challenges but also the opportunities for collective solutions. “If this high-level week is an indication, this house is fulfilling its purpose. The United Nations is still relevant. The test is whether we act,” she told delegates.
Conflicts dominated much of the debate, with repeated appeals for urgent action to protect civilians and reduce violence. Baerbock reminded members of the UN Charter’s centrality in resolving disputes peacefully and warned of the risks when it is disregarded.
“When bombs fall on civilians, when famine is used as a weapon, when sovereignty is trampled by force, it is the credibility of this Organization that is at stake,” she said.
Climate change and the looming 2030 deadline for the Sustainable Development Goals (SDGs) were also recurring themes. “Dozens of delegations spoke on the impacts of climate change and the ticking clock we face in delivering on the SDGs by 2030. That clock does not stop while we are here in this room,” Baerbock said, stressing the urgency of immediate action.
Institutional reform featured prominently, with Baerbock pointing to the Secretary-General’s reform proposals—including a revised budget and new mandates—as a pathway to strengthen the UN’s effectiveness.
“This is not only about trimming budgets; it is about strengthening delivery. It is about priorities,” she said, urging members to back reforms that would make the UN “better, stronger, and fit for purpose.”
