JAPAN TO WORLD: FRENCH INDOCHINA IS NOW OURS

Saigon (Ho Chi Minh City), French Indochina July 25, 1941

On September 21, 1937, Japanese planes bombed the capi­tal of China, Nan­king, shortly after igniting the Second Sino-Japa­nese War. Presi­dent Franklin D. Roose­velt expressed the shock of “every civil­ized man and woman” over “the ruth­less bombing” of Chinese civil­ians. Gen­er­ally, how­ever, U.S. and Euro­pean reac­tion to Japa­nese aggres­sion in China was mostly bark and no bite. Just under two years later, Adolf Hitler’s Luft­waffe bombed the capi­tal of Poland, War­saw, launching (as Euro­peans viewed it) the Second World War. But again, with the October 1939 onset of the so-called Phony War (Sitz­krieg, or “sitting war” in German), there was a lot of barking but little action. Not until April 1940, when Hitler turned his atten­tion to West­ern Europe and wolfed down Den­mark, Nor­way, the Nether­lands, Bel­gium, and France in less than three months, was the bark of the last dog standing—Great Britain—matched with bared teeth.

Back in Asia, the Japanese govern­ment and the German puppet regime of Vichy France signed a treaty in mid-Septem­ber 1940 per­mitting the sta­tioning of Japa­nese forces in parts of north­ern French Indo­china (in what is now Viet­nam). Four months later, at the end of Janu­ary 1941, Japan threw its weight behind a nego­ti­ated end to clashes between Vichy French forces and those of Thai­land along their con­tested border. The Japa­nese-im­posed armis­tice not only con­firmed Japan’s mili­tary occu­pa­tion of French Indo­china (modern-day Viet­nam, Cam­bodia, and Laos), but it opened the Vichy colony to min­er­al and agri­cul­tural exploit­a­tion by Tokyo’s expan­sionists in what Japan was calling the Greater East Asia Co-Pros­perity Sphere under its leader­ship. Eco­no­mic col­lab­o­ration was formalized by a treaty in early May.

On this date, July 25, 1941, Japan cemented its rela­tion­ship with Vichy France by moving air and naval forces into South­ern Indo­china and declaring the whole French colony a Japa­nese protec­to­rate. Vichy was permitted to admin­ister the colony, but in the interests of their Japa­nese masters. Japan’s diplo­matic and mili­tary moves set off a three-day whirl­wind of activity by West­ern govern­ments, which in pro­test froze Japa­nese assets in the U.S. (including dollars and gold), Canada, Great Britain, Aus­tralia, New Zea­land, and the Dutch East Indies (modern-day Indo­nesia). The U.S. and the London-based Dutch govern­ment-in-exile, both of which con­trolled vast oil reserves, upped the pain by halting ship­ments of oil and motor fuel to Japan, turning off 80 per­cent of Japan’s oil imports that could be used to further its expan­sionist aims over­seas and sus­tain the country’s over­all econo­mic well­being. Without new oil supplies Japan’s oil reserves would last only two years. The next moves by the country’s military-dominated leadership were predictable.



Japan’s “Place in the Sun”: The Greater East Asia Co-Prosperity Sphere, 1940–1945

Greater East Asia Co-Prosperity Sphere, 1942

Above: Maximum extent of the Greater East Asia Co-Pros­perity Sphere, 1942. Based on a geo­graphically smaller ver­sion called the New Order in East Asia (late 1938), the Greater East Asia Co-Pros­perity Sphere was invoked into being in late June 1940. Japa­nese idea­lists, nation­al­ists, econo­mic expan­sionists, and the mili­tary were all drawn by varying degrees to the “Asia for Asians” con­cept. Princi­pal actor in the cast of players was the Japa­nese mili­tary, whose role was to secure by con­quest the raw mate­rials that were unavail­able on the four home islands of Hokkaido, Honshū, Shikoku, and Kyūshū and, after the success­ful con­clu­sion of the Second Sino-Japa­nese War (begun in 1937), com­plete the building of a self-sufficient Japa­nese empire. Although Japan suc­ceeded in stimu­lating anti-West­ern senti­ment in East Asia as “elder brother,” the Co-Pros­perity Sphere never materi­alized into a unified block economically or militarily.

Standing in front of the Japan­ese Diet, or national par­lia­ment building, are (left to right) Ba Maw, head of Japa­nese-occupied Burma (State of Burma); Zhang Jinghui, Prime Minis­ter of Japan’s pup­pet state of Man­chu­kuo (Man­churia); Wang Jing­wei, head of the Japa­nese pup­pet govern­ment of China (Reor­ganized National Govern­ment of China); Hideki Tōjō, Prime Minis­ter of Japan; Prince Wan Waitha­yakon, envoy from the King­dom of Thai­land; José P. Laurel, Presi­dent of the Japa­nese-spon­sored Second Philip­pine Republic; and Subhas Chan­dra Bose, Head of State of the Provi­sional Govern­ment of Free India (the “observer,” since India was still under British rule). In a joint decla­ra­tion, the parti­ci­pants praised Asian soli­da­rity and con­demned West­ern colo­nialism but could not pro­duce any prac­ti­cal plans for either eco­no­mic develop­ment or inte­gration. The Co-Pros­perity Sphere collapsed with Japan’s surrender to the Allies in August 1945.
