The 77th United Nations General Assembly opened at the United Nations Headquarters in New York on the 13th. This is the first time that the UN General Assembly has held a meeting to fully return to offline since the outbreak of the new epidemic. In his opening speech, UN Secretary General Guterres said that the world was in danger and faced various difficulties in promoting peace, human rights and sustainable development. Threats and challenges such as conflict, climate change, poverty, inequality, hunger, division and distrust "require us to remain united". Guterres expressed his appreciation for the idea of "bringing solutions through solidarity, sustainability and science" used by the 77th President of the General Assembly to guide the work of the General Assembly, and emphasized that "the above three elements are crucial when we meet common challenges and formulate solutions for a better and more peaceful future". Keresh said: "We should work together to revive inclusive, networked and effective multilateralism to meet the most pressing challenges of mankind and commit to multilateralism that unites us. Our mission is to come together when differences occur and build bridges when serious differences occur." The 76th UN General Assembly held its closing meeting on the 12th. President Shaheed of the 76th session of the UN General Assembly delivered a speech, and Kelehi was sworn in as President of the 77th session of the UN General Assembly. The General Assembly of the United Nations is the main deliberative, supervisory and review body of the United Nations, which is composed of all Member States of the United Nations. The General Assembly holds regular sessions from September to December each year. The regular session is usually divided into two stages. The first paragraph is the general debate stage, and the second paragraph is the stage when the General Assembly considers the issues on the agenda. (Liu Xinshe)
