The San Francisco Peace Treaty, formally known as the Treaty of Peace with Japan, was signed in San Francisco and entered into force the following year on April 28 of 1952. 45 Allied countries including the United States, the United Kingdom and France, and Japan on the other side became Parties to the treaty. Major countries which were not parties to the treaty included the Soviet Union, China and India. South Korea wished to become a party to the treaty, but it was not given the opportunity to sign as it was not a member of the Allies. Article 2(a), the provision regarding the renunciation of the Korean peninsula, maintained its wording as presented within the revised US-British draft treaty as of June of 1951. Article 2(a) stipulates, “Japan, recognizing the independence of Korea, renounces all right, title and claim to Korea, including the islands of Quelpart, Port Hamilton and Dagelet.” (Ref. 1)
