Treaty of San Francisco

• 1. Introduction

  ›

  On the 8th of September 1951, inside the War Memorial Opera House in San Francisco, representatives of 49 nations gathered to sign a document that would formally close the most destructive war in human history. The Treaty of San Francisco was not merely a peace agreement. It was an attempt to rebuild a world order from the ground up, defining who would be compensated, which territories would change hands, and what kind of country Japan would be allowed to become.

  But the conference was shot through with absences as significant as its presences. China was not there. Korea was not there. The Soviet Union was there, but refused to sign. India was invited and stayed home in protest. Each empty chair carried its own political logic, and many of those unresolved tensions are still playing out today. Who had the right to speak for China? Who spoke for Korea? What exactly did Japan renounce when it renounced Taiwan? The treaty came into force on the 28th of April 1952, and those questions it left open have never fully closed.

• 2. Who Was Not Invited

  ›

  J.R. Jayewardene, Ceylon's Finance Minister, was inside the conference hall on the 8th of September 1951. Italy was not. Portugal was not. The absences were not accidental; they reflected a web of political calculations that shaped the peace before a single word was signed.

  China's exclusion stemmed from a direct standoff between the United States and the United Kingdom. Washington recognized the Republic of China government on Taiwan, while Britain had recognized the People's Republic of China in 1950. Neither side would yield, so neither Chinese government received an invitation. The compromise satisfied no one and left the question of China's rightful representation unresolved for decades.

  Korea found itself in the same bind. With South Korea and North Korea each claiming to represent the Korean people, conference organizers did not invite either. The practical consequence was severe: South Koreans directly harmed by Japanese wartime actions were not entitled to compensation under Article 14 of the treaty, because South Korea was not a signatory state.

  India received an invitation and declined it. The Indian government judged that certain provisions placed unacceptable limits on Japanese sovereignty and independence. India signed its own separate agreement, the Treaty of Peace Between Japan and India, on the 9th of June 1952, framed explicitly as giving Japan a position of honor and equality. Pakistan's path to the table was different: it had only become independent from Britain in 1947, after the war had ended, but was treated as a successor state to British India, recognizing that hundreds of thousands of people who were now Pakistani citizens had fought the Axis powers under the British Empire.

• 3. Ceylon Speaks for Asia

  ›

  When J.R. Jayewardene rose to address the conference, many delegations were still pushing for punishing terms. The Finance Minister from Ceylon, the island nation now called Sri Lanka, chose a different direction.

  Jayewardene acknowledged that Ceylon had suffered. Air raids, the stationing of large Allied armies under the South-East Asia Command, and what he described as the forced tapping of rubber when Ceylon was the Allies' only source of natural rubber had all caused damage. His government had a legitimate claim to reparations. He told the conference it would not make one. His reasoning drew on Buddhist teaching: "hatred ceases not by hatred but by love."

  He closed his speech with a passage directed at the defeated nation directly: "This treaty is as magnanimous as it is just to a defeated foe. We extend to Japan the hand of friendship and trust that with the closing of this chapter in the history of man, the last page of which we write today, and with the beginning of the new one, the first page of which we dictate tomorrow, her people and ours may march together to enjoy the full dignity of human life in peace and prosperity."

  The hall responded with extended applause. The New York Times described his voice as that of "free Asia, eloquent, melancholy and still strong with the lilt of an Oxford accent," dominating the conference that day. His speech stood in sharp contrast to the Soviet delegation's reaction, which was to object at every procedural turn.

• 4. Moscow Says No

  ›

  Soviet Deputy Foreign Minister Andrei Gromyko led his delegation into the War Memorial Opera House on the 8th of September 1951 and immediately set about trying to stop the proceedings.

  The Soviet objections were extensive. A statement issued on the day of signing laid out their position at length. Gromyko argued that the treaty provided no safeguard against a revival of Japanese militarism. He argued that China had been shut out despite being among the main victims of Japanese aggression. He contended that the Soviet Union had not been properly consulted during the treaty's drafting. His most pointed charge was that the agreement effectively turned Japan into an American military base and drew it into a military coalition aimed at the Soviet Union.

  On the specific matter of territory, Moscow insisted that the treaty violated the Yalta agreement by failing to formally recognize Soviet sovereignty over South Sakhalin and the Kuril Islands. The Soviet delegation made several procedural moves to slow or derail the conference. None succeeded. Czechoslovakia and Poland also refused to sign, leaving three of the 51 participating nations outside the agreement.

  The consequences of that refusal stretched forward years. Japan and the Soviet Union did not sign a declaration formally ending their war and restoring diplomatic relations until the 19th of October 1956.

• 5. Territories Renounced

  ›

  Article 3 of the treaty created a zone of deliberate ambiguity around a string of Pacific island groups. The Bonin Islands, the Volcano Islands including Iwo Jima, and the Ryukyu Islands including Okinawa were placed under a potential United Nations trusteeship. That option was never actually pursued.

  The Amami Islands were restored to Japan on the 25th of December 1953. The Bonin and Volcano Islands came back on the 5th of April 1968. U.S.-Japan negotiations in 1969 authorized the transfer of authority over the Ryukyus, which took effect in 1972. The return of the Ryukyus in 1972 also included the nearby Senkaku Islands. Both the People's Republic of China and the Republic of China have since argued that this transfer did not resolve the ultimate sovereignty question over the Senkakus, a dispute that remains active.

  The treaty also formally stripped Japan of rights it had held under the Boxer Protocol of 1901, along with its claims to Korea, Formosa, the Pescadores, the Kuril Islands, the Spratly Islands, Antarctica, and South Sakhalin. Japan's legal renunciation of Taiwan was notably silent on who received it. In 1955, U.S. Secretary of State John Foster Dulles, who co-authored the treaty, stated plainly that Japan had "merely renounced sovereignty over Taiwan" and that the disposition of Taiwan was not an internal matter for China to resolve. The ROC Ministry of Foreign Affairs rejected that interpretation, pointing to the Cairo Declaration and the Potsdam Declaration as evidence that Taiwan was meant to return to Chinese control.

• 6. Reparations and Compensation

  ›

  Article 14 of the treaty contained a frank acknowledgment: Japan's resources were not sufficient to make full reparation for all the damage and suffering it had caused, while also maintaining a functioning economy. The solution was to require Japan to negotiate compensation agreements with affected countries, offering Japanese labor for production, salvage work, and related services rather than cash payments alone.

  The Philippines and South Vietnam were identified as priority recipients. The Philippines eventually received a reparations settlement, with Japan paying the equivalent of $550,000,000 in yen under a bilateral treaty signed in May 1956; that treaty was ratified by the Philippines on the 16th of July 1956. South Vietnam received a settlement in 1959. Burma, which had not signed the original treaty, reached its own bilateral agreement in 1955 for the equivalent of $200,000,000. Indonesia followed with a bilateral treaty on the 20th of January 1958 covering $223,080,000. The last payment under all these arrangements went to the Philippines on the 22nd of July 1976.

  For Allied prisoners of war, Article 16 directed Japan to transfer assets held in neutral or enemy countries to the International Committee of the Red Cross, which would then distribute the proceeds to former POWs and their families. Japan paid £4,500,000 to the Red Cross under that provision. Article 16 later became the legal ground on which a Tokyo court dismissed a 1998 lawsuit brought by former Allied POWs seeking additional compensation, ruling that the San Francisco Treaty had settled those claims.

  The People's Republic of China, which was not present in San Francisco, addressed the question on its own terms. On the 29th of September 1972, in the Joint Communique between Japan and the PRC, the Chinese government formally renounced its demand for war reparations from Japan.

• 7. Taiwan's Unresolved Status

  ›

  The treaty's travaux preparatoires, the internal working documents of the drafting process, show that the states present in San Francisco broadly agreed on one thing: Taiwan's legal status was temporarily undetermined and would need to be resolved later through peaceful settlement and self-determination.

  On the same day the San Francisco Treaty came into force, the 28th of April 1952, Japan and the Republic of China signed a separate agreement in Taipei called the Treaty of Taipei. The timing was tight enough that the apparent sequence between the two treaties was actually a function of time zone differences between San Francisco and Taipei.

  The Treaty of Taipei stated that residents of Taiwan and the Pescadores were nationals of the ROC. But it stopped short of language saying Japan recognized that sovereignty over Taiwan had been transferred to the ROC. That gap has fueled decades of argument. Political scientist Alain Guilloux has written that the United States deliberately kept Taiwan's international status open when drafting the treaty.

  Some supporters of Taiwan independence cite the San Francisco treaty as evidence that Chinese sovereignty over the island, whether under the ROC or the PRC, was never legally established and must be resolved through self-determination. The ROC Ministry of Foreign Affairs counters that the Instrument of Surrender of Japan, which accepted the Potsdam and Cairo Declarations, made the transfer to the ROC implicit. The question historian Rana Mitter identified as central to the South China Sea dispute applies here as well: the absence of contact that followed from China's exclusion in 1951 made it impossible to build shared norms around what the treaty had actually meant.
