# The Report Lytton Brought Back, the Assembly Matsuoka Left

This is a contemporary historical narrative prepared with AI assistance and checked against the sources listed below, not a memoir or submission by a commissioner or diplomat.

On September 1, 1932, American general Frank McCoy called on U.S. minister Nelson Johnson in Peiping. The commission was preparing to leave China; its report was nearly finished. He brought news that all five commissioners could sign it.

Agreement had not been assured. McCoy told Johnson that, during the preceding fortnight, the position of the French commissioner, General Henri Claudel, had raised fears of a divided report. They had finally found an acceptable formula. They agreed that the Japanese action at Mukden on September 18, 1931, could not be justified as legitimate self-defense.

McCoy still hoped the tone of the report would help. Setting the facts together might moderate Japan's attitude. When Johnson asked about the future, he offered no assurance. Five men could agree on paper; governments and armies in East Asia had their own courses to pursue.

Three days later, Lytton and his colleagues signed the report in Peiping. It would carry the voices they had heard back to Geneva.

What investigators could take away

After the Mukden Incident, China appealed to the League of Nations to halt Japanese military action. In December 1931, the League agreed to send five investigators. The British chairman, Lord Lytton, worked with commissioners from the United States, France, Germany and Italy. Their authority extended to inquiry and recommendations, not command over either country's troops.

China appointed Wellington Koo as assessor; Japan appointed Isaburo Yoshida. In spring 1932, Koo's entry into Manchuria itself became a matter for negotiation. The party divided: some traveled by rail through Shanhaiguan, others accompanied Koo through Dairen into the Japanese railway zone. The objection to his entry into “Manchukuo” territory was withdrawn only after the commissioners reached Changchun.

An inquiry intended to hear different views depended on the authorities on the ground even to bring its accompanying personnel to the scene.

Officials, soldiers and organized deputations appeared at public interviews. Private messages could tell a different story. Some people who submitted statements later said Japanese hands had written or substantially revised them. Officials sent word that they had remained under pressure: what they said in Japanese company should not simply be believed.

Letters arrived too. After returning to Peiping, the commission had its correspondence translated and organized. It judged that all but two of 1,550 Chinese letters were strongly hostile to the new regime and the Japanese. These were letters received, not a poll of Manchuria. But orderly declarations of support at public interviews no longer accounted for everything the commissioners had heard.

Another inquiry led back to the railway. Japan presented the September 18 operation as self-defense. The commission noted that the southbound train from Changchun had nevertheless arrived on time: the railway damage was insufficient to justify the military action. Set beside the night's operations, that fact helped it reject the self-defense claim.

In a private letter to Washington on June 29, Johnson had already worried that the opportunity would be lost. The commission, he thought, could lift the curtain concealing events in Manchuria; after it left, the curtain might fall again. He urged McCoy and others to publish their findings separately from any settlement plan, lest arguments about proposals bury the facts as well.

In August, Secretary of State Henry Stimson authorized him discreetly to convey a similar priority: the report's greatest potential value lay in a complete, objective statement and analysis of facts. Diplomats could already see two different tasks ahead: establishing what had happened and changing what happened next.

Reality moved ahead of publication

The commission offered more than findings. It rejected recognition and maintenance of the existing “Manchukuo” regime, but also rejected simply restoring every pre-incident arrangement. It envisaged substantial Manchurian autonomy consistent with China's sovereignty and administrative integrity, together with arrangements for Japanese interests.

This was not a plan for China simply to recover everything as before. A special constabulary, foreign advisers, negotiations and new treaties were among its proposals. Lytton wanted them to make agreement possible. They also provided new grounds for disagreement.

A new government already had offices and lists of officials.

U.S. consul general Myrl Myers studied the names published by the Changchun government. On October 1, he reported 509 Chinese, Manchu and Mongol officials and 312 Japanese. The list might be incomplete; numbers alone could not reveal who exercised authority. More telling was that the leading officers of the General Affairs Board were all Japanese, as were the heads of general-affairs offices in many departments.

Someone seeking approval for a transaction could find that a minister's nationality told only part of the story. Myers judged Chinese officials' freedom of action to be constrained, with Japanese officials or advisers controlling or checking departmental work. His separately produced consular report converged with the commission's observations of power within the new regime.

Before the inquiry was published, Japan had recognized “Manchukuo.”

At the protocol-signing ceremony in Changchun on September 15, an American officer, Lieutenant Brown, watched Japanese forces effectively direct proceedings. Traffic in the city was tightly restricted; the prime minister addressed the press in Japanese.

A telegram sent two days later also relayed local officials' and Japanese advisers' expectation that recognition would enable requests for additional Japanese troops and assistance. The commissioners were preparing to submit the new state's origins to the League. Japan had already made recognition and agreement a basis for further action.

In Geneva on September 24, the League Council considered Japan's request for another six weeks to prepare observations on the report. Its president expressed regret that Japan had recognized the regime and concluded a treaty before the investigation could be considered. China's representative, V. K. Yen, opposed postponement and sought referral to the Assembly's Committee of Nineteen. The Council rejected his plea, granted the delay and provisionally fixed November 14 for discussion.

For a meeting, the interval was a matter of scheduling. In occupied territory, it meant more days of events.

After the seals were broken

At seven on the morning of October 2, Washington's Far Eastern Division opened a sealed package. The hour corresponded to one in the afternoon in Geneva. Officials and journalists were present. Inside were two copies of the report and two sets of maps.

Months of visits, argument and compilation had become something the world could read. The time for opening the seals could be agreed. What readers would do afterward could not be enclosed with the papers.

The following day in Nanking, Chinese foreign minister Luo Wengan singled out two findings: Japan's military actions could not be considered legitimate self-defense, and “Manchukuo” had not arisen from a genuinely spontaneous independence movement. He commended the inquiry while stating that the Chinese authorities were studying the report carefully.

It supported China's appeal but also proposed arrangements China would have to confront. Accepting its findings did not automatically settle disagreements over autonomy, advisers or conditions for negotiations.

On October 26, in the foreign secretary's office at the House of Commons in London, Lytton discussed the next steps with John Simon, Norman Davis and others. He challenged the criticism that the report merely handed the dispute back to China and Japan. The League should first define the principles within which the parties would be invited to negotiate.

Lytton preferred to go as far as possible toward conciliation before considering pressure. Yet waiting had a condition: states must make clear that they would never recognize what Japan had done in Manchuria. Time could not remedy matters if the rights and wrongs remained unsettled.

Davis opposed expelling Japan from the League. What alternative, Lytton asked, could satisfy states wanting stronger action? After a pause, Davis said he did not know. The discussion yielded no common plan of enforcement.

On November 19, Yosuke Matsuoka called on American diplomats Hugh Wilson and Davis. His position was firm. Nothing would divert Japan from its existing Manchurian policy; Japan would reject a settlement disregarding “Manchukuo” and Japanese recognition of it. He warned of Japanese public hostility toward America and raised departure from the League as a possible consequence.

Davis replied that an irreconcilable position left little prospect of a constructive settlement. Washington's instructions two days later did not treat the warning as a reason to retreat. Stimson judged that Japan was making itself the sole judge of fact and law, challenging an inquiry it had helped establish. That was the American diplomatic assessment. Japan continued to promote its account of self-defense and an independent local movement.

Votes inside, decisions outside

On February 24, 1933, the special Assembly voted. Before it lay the Assembly report and recommendations drafted by the Committee of Nineteen, drawing importantly on the inquiry. The five commissioners' work had not arrived for the first time that morning.

China offered to accept the recommendations; Matsuoka urged rejection. The roll call produced forty-two affirmative votes, Japan's negative vote and Siam's abstention. Under the applicable procedure, President Paul Hymans announced adoption. He also reminded delegates that the recommendations were not enforceable in the manner of an arbitral award: they remained an offer of cooperation in settling the dispute.

Matsuoka then declared that Japan and the other members held different views on achieving peace in East Asia. When he finished, the entire Japanese delegation left the chamber.

In his telegram that day, U.S. consul Gilbert preserved a distinction. Matsuoka had not explicitly declared Japan's future legal status in relation to the League. What had happened was a walkout. His speech had not completed formal notification of withdrawal.

That same day in Washington, Herbert Hoover wrote to Stimson. He opposed military and economic sanctions, fearing a wider conflict that might involve the United States. He preferred public opinion and nonrecognition. Stimson later penciled onto the letter that, after discussion, the president had agreed not to announce this position publicly for the time being. Support for the findings still stopped short of a commitment to coercive measures.

On March 27, Japan formally notified its intention to withdraw. Its communication reiterated self-defense and Manchukuo's claimed independence, accusing most members of failing to understand East Asian realities. An accompanying imperial rescript still proclaimed willingness to work for peace. The government was leaving an organization that refused to accept its explanation.

China's answer emphasized the interval between notice and withdrawal. Luo pointed to the Covenant's two-year notice provision and its condition that international and League obligations be fulfilled. A notification could not immediately erase existing responsibilities. The words debated at Geneva had not all ceased to matter when Matsuoka walked out.

On March 28, the League's Advisory Committee heard of the notice and continued exploring the practical meaning of nonrecognition: passports, currency, membership of international organizations, contracts and consular authorizations. Discussion of an arms embargo was postponed again, pending further study and governments' positions.

The report had supplied findings that could be used. Implementation remained divided into matters still to be discussed.

On March 31, Matsuoka visited the new U.S. secretary of state, Cordell Hull, in Washington. There was no substantive Far Eastern negotiation. He left a booklet of his speeches and asked Hull to read it. Before departing, he spoke against war between the two countries and asked that Japan have more time to make itself understood. Hull was restrained; the courtesy call produced no new arrangement.

McCoy had hoped that bringing the facts together might moderate Japan's attitude. The facts were now public, and the positions clearer. Matsuoka continued his journey with his own explanation. The voices the investigators had brought back remained beside recommendations still unfulfilled, waiting for another answer.

Changchun's modern city reference represents the city, not the protocol-signing building. Geneva, London and Washington are likewise city references for individually supported events. The Japanese notice's page gives no place of production, so it is not automatically assigned to Tokyo.
