Forty-eight nations signed the treaty while Czechoslovakia, Poland, and the Soviet Union refused to participate. China remained absent because the United States and the United Kingdom could not agree on which government represented the Chinese people.
Article Two of the treaty officially renounced Japan's treaty rights derived from the Boxer Protocol of 1901 and its claims over Korea, Formosa, and the Pescadores. The document also stripped Japan of sovereignty over the Kuril Islands, Spratly Islands, Antarctica, and South Sakhalin.
Afghanistan, Burma, India, Nepal, Yemen, and Yugoslavia accepted invitations but chose not to participate in the proceedings. India later signed a separate peace treaty with Japan on the 9th of June 1952 arguing that certain provisions limited national sovereignty.
Diplomatic relations between Japan and the Soviet Union would not resume until the 10th of October 1956 when both nations signed a Joint Declaration ending their state of war.
