Why did the Soviets create the bombing of Huanggutun?

The Huanggutun incident was an incident in which the Japanese Kwantung Army killed Zhang, the marshal of the Republic of China and the leader of the Fengzhi warlord.

1928 At 5: 30 a.m. on June 4th, Zhang's special train passed Sandong Bridge at the intersection of Jingfeng and Nanman Railway, and the train was blown up by explosives laid by the Japanese Kwantung Army, and Zhang was seriously injured. After being sent back to Shenyang, he died on the same day.

Event background

Zhang:1April, 927, after Tanaka took office, he demanded the railway rights from Zhang and forced Zhang to solve the so-called "Manchu-Mongolian unsolved case", which aroused the anti-Japanese anger of the northeast people. On September 4th, 20,000 people demonstrated in Shenyang, shouting "Down with Tanaka Cabinet". Under the impact of the national anti-imperialist wave and Zhang's own national consciousness, the government failed to meet all Japan's requirements in Manchuria, such as building roads, mining, setting up factories, renting land, emigrating, etc., and resisted them, which was intolerable to the Japanese cabinet, while the Japanese Kwantung Army believed that the anti-Japanese demonstrations of the northeast people were instigated by Zhang and held a grudge against him.

1On April 5, 928, Chiang Kai-shek was sworn in in Xuzhou to expand his territory and carried out the "second northern expedition" against the old Beiyang warlord headed by Zhang. On April 9, the first army launched a full-scale attack. On April 30th, armies from all countries launched a general attack on Jinan. That night, Zhang Zongchang rate areas abandoned north to flee. In late May, the national army approached the Beijing-Tianjin region. Zhang Jian, the "Marshal of the Republic of China" entrenched in Beijing, saw that the general trend was gone. On June 2, he issued a "power on" and announced his withdrawal from Beijing and his return to the Northeast.

This time, when Zhang returned to the northeast of China, Japan put forward an ultimatum, coercing him to agree to Japan's demands, but Zhang refused to let go and relied on hundreds of thousands of troops in his own hands. Therefore, the Japanese Kwantung Army decided to get rid of Zhang's eyesore on his way back to the Northeast.
