“The Charter of the United Nations that you just signed,” President Truman said in his speech at the last session, “is a solid structure on which we can build a better world. History will honor you for that. Between the victory in Europe and the final victory, in this most destructive of all wars, you won a victory against the war itself… Thanks to this charter, the world can rejoice in the time when all worthy people can be allowed to live decently as free men. Today, in the seventh decade, the United Nations is known around the world. But how many people know what it feels like or how it works? Or why, as nearly 200 heads of state and government gather this week for the 74th session of their annual general meeting, did the institution fight to keep the promise of its founders: make the world a better and more peaceful place? The origins of the United Nations lie in the 1941 Atlantic Charter, signed by U.S. President Franklin Roosevelt and British Prime Minister Winston Churchill, which were intended to help ensure peace and security for all peoples. On 1 January 1942, 26 countries, including the Netherlands, approved the principles of the Atlantic Charter enshrined in the UN Declaration. The Charter of the United Nations was signed in June 1945 at a conference in San Francisco, under the leadership of Great Britain, China, the Soviet Union and the United States. There was, for example, the question of the status of “regional organizations.” Many countries had their own regional defence and mutual aid provisions.
There was, for example, the Inter-American system and the Arab League. How should such agreements be linked to the World Organization? The Conference decided to give them a part of the peaceful settlement and, in certain circumstances, enforcement measures, provided that the objectives and actions of these groups are consistent with the objectives and objectives of the United Nations. The next day, delegates from the Veterans Memorial Hall Auditorium signed the Charter. China first signed because it had been the first victim of an Axis power.  In the closing speech of US President Harry S. Truman, it was said that there were 850 delegates and that their advisers and collaborators, as well as the secretariat of the conference, brought the total to 3,500. In addition, there were more than 2,500 representatives of the press, radio and information, as well as observers from many companies and organizations. Overall, the San Francisco conference was not only one of the largest in history, but perhaps the largest international assembly ever held.
The heads of delegations from the producing countries succeeded each other as presidents of the plenary sessions: Anthony Eden of the United Kingdom, Edward Szczecous of the United States, T. V. Soong of China and Vyacheslav Molotov of the Soviet Union. At subsequent meetings, Lord Halifax defended Mr. Eden, V. K. Wellington Koo for T. V. Soong and Mr.
Gromyko for Mr. Molotov. The United Nations Conference on the International Organization (UNCIO), known as the San Francisco Conference, was a gathering of delegates from 50 allied nations held from April 25, 1945 to June 26, 1945 in San Francisco, California, United States of America. At that meeting, delegates reviewed and rewrote the dumbarton Oaks Agreements of the previous year.  The Convention resulted in the creation of the Charter of the United Nations, which was opened for signature on 26 June, the last day of the conference. The conference took place in various locations, including the War Memorial Opera, with the Charter signed on June 26 at the Fall Theatre at the Civic Centre. A square next to the city`s civic center, called “UN Plaza,” recalls the conference. Monday`s UN climate summit at the General Assembly is expected to highlight concrete promises by heads of state and government to wean the global fossil fuel economy to avoid the worst impacts of global warming.
