JAPAN PROTESTS U.S. EMBARGO

Washington, D.C. · October 7, 1940

In the 1930s Japan’s statesmen and military leaders in China were acutely aware that their eco­nomy and armed forces were depend­ent on im­ports from the United States and its colo­nial friends who had holdings in the Asia Pacific region: the Amer­i­cans in the Philip­pines, the Brit­ish in Malaya (now Malay­sia), the French in Indo­china (now Viet­nam, Laos, and Cam­bo­dia), and the Dutch in the East Indies (now In­do­ne­sia). The Japa­nese im­ported prac­ti­cally every domes­tic and in­dus­trial item they con­sumed or pro­duced, much of it from a geo­graphi­cal area in which they felt they should domi­nate. Imports included most metals, rubber, and food, including rice. The U.S. supplied roughly 80 per­cent of Japan’s oil; the rest came from the oil-rich islands around the Java Sea—Bor­neo, Suma­tra, and the Dutch East Indies. Wash­ing­ton clearly under­stood Japan’s utter depen­dence on oil and other over­seas re­sources for its eco­no­mic secu­rity. On this date in 1940 in Wash­ing­ton, D.C., Japan’s am­bas­sador pro­tested the U.S. em­bar­go on avi­a­tion fuel and ma­chine tools and the ban on the ex­port of iron and steel scraps as an “un­friendly act.” The object of the em­bar­goes (these and suc­ceeding ones) served two pur­poses: to en­cour­age the Japa­nese to halt mili­tary action in China, begun in 1937, and to assist the Chin­ese Nation­alist army under Gene­ralis­simo Chiang Kai-shek in waging war against the ag­gres­sor. The next day, Octo­ber 8, the State Depart­ment advised U.S. citi­zens to leave the Far East “in view of ab­nor­mal con­ditions in those areas.” The State Depart­ment arranged for three pas­sen­ger liners to sail to Yo­ko­ha­ma and Kobe, Japan, as well as to Shang­hai and Chin­wang­tao in China to repa­tri­ate Amer­i­cans. A State Depart­ment em­ployee wrote in his diary following the news that Japan had joined with Ger­many and Italy in the Tri­par­tite Pact, which was a ten-year mili­tary and eco­no­mic agree­ment signed on Septem­ber 27, 1940, that Japan hoped to use it as a bar­gaining chip with America: “And so we go—more and more—farther and farther along the road to war. But we are not ready to fight any war now—to say nothing of a war on two oceans at once.” Ready or not, war came on Decem­ber 7, 1941, with the most “un­friendly act” of all—the Japa­nese sur­prise attack on the U.S. naval base at Pearl Harbor, Hawaii.

“Incidents” on the Chinese Road to World War II in the Pacific

Japan’s Kwan­tung Army on the Chin­ese main­land fabri­cated a bombing inci­dent on a tiny por­tion of the Japa­nese-owned South Man­chu­ria Rail­way as a pre­text to occupy Man­chu­ria, a pro­vince semi-inde­pendent of China, and North­east China. Both regions were rich in mine­ral and agricul­tural resources. Most West­erners believed the “Muk­den Inci­dent,” although coming on top of other Sino-Japa­nese inci­dents, was way over­blown and should not have led to Japan’s take­over of Man­chu­ria, where the Japa­nese installed a pup­pet govern­ment in a “state” they named Manchukuo.

Right: Manchukuo became the spring­board for further Japa­nese aggres­sion in China. Out­lying pro­vinces were annexed into Man­chu­kuo or turned into buffer zones, effec­tively under Japa­nese occu­pa­tion. By the start of 1937 all the areas north, east, and west of the large Chin­ese city of Bei­jing were con­trolled by Japan. On July 7–8, 1937, the Japa­nese pro­voked an­other “inci­dent” at the eleven-arch granite Marco Polo bridge southwest of Beijing.

Above: The heightened tensions of the Marco Polo bridge inci­dent led directly to Japan’s full-scale inva­sion of China in the Second Sino-Japa­nese War (1937–1945), begin­ning with the Battle of Bei­jing-Tianjin (early July to early August 1937) and the Battle of Shang­hai (August 13 to Novem­ber 26, 1937). In the photo on the left Japa­nese troops are shown passing from Bei­jing into the Tar­tar City through Chen-men, the main gate leading to the palaces in the For­bidden City, some­time in mid-August 1937. In the photo on the right Japa­nese marines cele­brate their success­ful landing near Shang­hai that same month. Approx­i­mately 200,000 Chi­nese and 70,000 Japa­nese died during Japan’s three-month attempt to take Shanghai.
