The "September 18th Incident" was not accidental. This is an important aggressive step taken by Japanese imperialism to annex China and rule Asia and the Pacific. The Japanese have long coveted northeast China. Before the "September 18th Incident", it had seized Lushun, Dalian and Manchuria railways through the Russo-Japanese War and sent troops to station them, which was the premise of its conspiracy to implement the incident.

1in the summer of 927, the Japanese cabinet held an "Oriental Conference" in Tokyo, and formulated a "China policy program", clearly claiming that the northeast of China "has a great interest in (Japan's) national defense and national survival". In July of the same year, Cabinet Prime Minister Yoshiichi Tanaka presented the "Imperial Positive and Fundamental Policy towards Manchuria" (the infamous "Tanaka Memorial") to the Emperor, and publicly declared: "If you want to conquer China, you must first conquer Manchuria; If you want to conquer the world, you must first conquer China. " Thus, the arrogant strategy of taking "Manchuria" as the base of aggression was established. Starting from 1929, the Japanese General Staff Headquarters and the Kwantung Army secretly organized three "staff trips" in the three northeastern provinces of China to scout the situation and make a battle plan for invading the Northeast. 193 1 In June, the Japanese General Staff and the War Department formulated the Outline for Solving the Manchu-Mongolian Problem, which determined the specific steps of occupying the Northeast by force; In July, the army chief of staff secretly transported siege heavy artillery to Shenyang, aiming at Beidaying, the resident of Northeast Army. In August, Minami Jiro, Minister of the Japanese Army, shouted at the Japan National Division Chiefs' Meeting: The Manchu-Mongolian problem can only be solved by force. And then further prepare to launch this war. After carefully preparing for the war of aggression, Japanese imperialism flagrantly launched the "September 18th Incident", which opened the prelude to full-scale armed aggression against China and even the Asia-Pacific region. The "September 18th Incident" aroused the anti-Japanese anger of the people all over the country. People of all countries demand resistance to Japan and oppose the non-resistance policy of Zhang Xueliang and Nanjing National Government. Under the influence of national justice and patriotic party members, the people in Northeast China rose up and launched guerrilla war against Japan, and Northeast Volunteers and various anti-Japanese armed forces appeared one after another. 1February, 936, the Northeast Anti-Japanese Forces were unified and reorganized into the Northeast Anti-Japanese Coalition Forces. 1937 After the July 7th Incident, the anti-Japanese allied forces United with the broad masses, further launched an extensive and lasting armed struggle against Japan, and effectively cooperated with the whole nation in the war of resistance.
