On September 18, 1931, the long-planned Japanese Kwantung Army suddenly shelled the North Camp in Shenyang, firing the first shot of Japan's invasion of northeast China. In the four months that followed, the Japanese occupied nearly one million square kilometers of great rivers and mountains in northeast China until The unconditional surrender of Japan on August 15, 1945, and occupied northeast China for 14 years.
During the 14 years since the fall of northeast China, the Japanese Kou turned northeast China into a vassal territory of the Japanese Empire and as an important strategic rear base for the Japanese Kou to invade China, dominate Asia, and conquer the world.
At that time, The northeast was one of the most developed areas in terms of industry, agriculture, transportation, foreign trade, urbanization level, culture and education. According to historical records, the northeast region at that time already had 80% of the country's output of steel, 93% of oil, 55% of gold, 30% of electricity, 47% of railways, 38% of foreign trade, and so on; In addition, the northeast region is also extremely rich in economic resources such as food crops, forests, and leather.
According to historical records, the Japanese Kou plundered a total of 115 million tons of coal in the northeast; 13.08 million tons of steel; 3 million tons of pig iron; gold increased from 111,000 grams to 3.57 million grams per year; timber from 897,000 cubic meters per year to 2.771 million cubic meters per year, and so on. A large amount of historical evidence shows that more than 95% of these important industrial raw materials are continuously shipped to Japan.
In addition, the Japanese also organized five large-scale Japanese emigration to the northeast and seized high-quality cultivated land in the northeast region. Since 1940, the Japanese Kou have plundered more than 33.3 million tons of grain for five consecutive years, of which 11.3 million tons were shipped to Japan to meet the needs of expanding the scale of the war in China and supply the Pacific War, and another 5 million tons were reserved for the military food of the million Kwantung Army, and the rest were shipped to Various Theaters of China for reserves.
And, of course, the most important oil. The oil resources in the northeast are mainly concentrated in the Daqing oil field and the Liaohe oil field, during World War II, the Japanese Kou "Manchurian Oil Company" once drilled a 1,000-meter-deep exploration well in the edge area of the Daqing oil field, and the flow was viscous, high sulfur content, and the flow was very small, so the Japanese Kou gave up the plan to continue to find oil in the Daqing area. The crude oil of the Liaohe Oilfield was buried at 6,000 meters underground, which was unattainable by the technology at that time.
But that's not to say that Japan didn't get oil in the Northeast. Japan's plundering of Northeast oil is mainly reflected in the "artificial oil", the most serious of which is Fushun shale oil. The oil shale of Fushun Coal Mine is about 120 meters thick and has a reservoir of 5.5 billion tons, which is calculated according to the average oil content of 5.5%, and 300 million tons of crude oil can be obtained. Rikou established a refinery in 1928, began actual operations in 1930, and by 1930, produced 57,000 tons of crude oil by 1930.
As the only oil resource controlled by the Japanese Kou at that time, the Japanese Kou repeatedly rebuilt and expanded the Fushun refinery, and the annual output of crude oil reached 145,000 tons in 1936, increased to 191,000 tons in 1939, and reached 300,000 tons in 1942. Basically all of this crude oil is shipped to Japan for military use.
Although the Japanese are shrewd and capable, hard-working and hard-working, the reason why Japan was able to take off was developed by the wealth plundered in World War II. These are still incomplete statistics, if you calculate carefully, the wealth that Japan has plundered from China can at least recreate another Japan. World War II reduced Japan to rubble, and without the resources seized from other countries, the Japanese could not have developed Japan to where they are today, even if they had the ability to fly.
In addition, the Nationalist government abandoned its post-war claims against Japan, so that Japan could move forward lightly after the war and quickly recovered its economy, while the devastated Tohoku region is still struggling to move forward.
