連合国共同宣言
The San Francisco Conference, formally the United Nations Conference on International Organization (UNCIO), began as scheduled on 25 April 1945 with the goal of drafting a charter that would create a new international organization. The Big Four, which sponsored the event, invited all forty-six signatories to the Declaration by United Nations. Conference delegates invited four more nations: Belorussian Soviet Socialist Republic, the Ukrainian Soviet Socialist Republic, recently liberated Denmark and Argentina.
