Sino-Japanese War Ends: Peace Treaty Reshapes East Asia

Japan and the Republic of China signed the Treaty of Taipei on April 28, 1952, formally ending the state of war that had existed between them since the Marco Polo Bridge Incident of July 1937. The treaty came into force the same day as the San Francisco Peace Treaty, which restored Japanese sovereignty and ended the Allied occupation. Together, the two agreements settled, at least legally, the conflicts of the Pacific War. The political reality was far more complicated than the signatures suggested. The Treaty of Taipei was necessitated by the Chinese Civil War. The San Francisco conference in 1951 had invited neither the People's Republic of China nor the Republic of China to sign the broader peace treaty, because the Western powers and the Soviet bloc could not agree on which government represented China. The United States, which recognized the Republic of China on Taiwan as the legitimate Chinese government, pressured Japan to sign a separate bilateral treaty with Taipei. Japan complied, though Prime Minister Yoshida Shigeru privately expressed discomfort with a treaty that implicitly denied the reality of Communist control of the mainland. The treaty's terms required Japan to renounce all territorial claims derived from the 1895 Treaty of Shimonoseki, including Taiwan and the Pescadores, without specifying to whom these territories were renounced. This deliberate ambiguity reflected the unresolved question of Taiwan's sovereignty, a question that remains unresolved today. Japan also waived Chinese reparation claims, a concession that the Republic of China, dependent on American support and in no position to negotiate from strength, accepted reluctantly. The Treaty of Taipei became a dead letter in 1972 when Japan normalized relations with the People's Republic of China and severed diplomatic ties with Taiwan. Beijing declared the Taipei treaty illegal and void from its inception. The episode illustrates how the unfinished business of World War II in Asia was entangled with the Cold War, producing legal arrangements that satisfied geopolitical convenience rather than historical justice. Japan's wartime conduct in China, including the Nanjing Massacre and the use of chemical and biological weapons, remained sources of deep anger that no treaty could extinguish.
