In 1979, China launched a self-defense counterattack against Vietnam. More than forty years have passed since the end of this war, and in these years, Vietnam has not turned over. So why has it been so difficult for Vietnam to turn around? Because of the 3 orders issued by Xu Shiyou before the retreat, now we know how clever.
Aid to Vietnam
The first is the removal of supplies from the Vietnamese border. China has been assisting Vietnam since the outbreak of the Vietnam War between Vietnam and the United States. In the past two decades, China has aided Vietnam with almost $20 billion in supplies, equivalent to China's GDP for a year at the time. It should be known that at that time, China's productivity was not high, and there were still food controls in the country, and there would be famine from time to time.
However, after Vietnam drove away from the United States, it immediately turned its spearhead to us. Therefore, at that time, Xu Shiyou ordered that how much Vietnam had eaten in the first place should now be let out in its entirety. Before the retreat, China removed a large amount of supplies from the Vietnamese border, which was certainly not worth 20 billion US dollars, but also caused Vietnam to suffer a lot of losses.
17 degrees north latitude line
The second is to demolish industrial facilities along the Vietnamese border, destroy Vietnamese farmland, and slaughter Vietnamese cattle. When Vietnam and the United States fought the Vietnam War, China drew a line of 17th parallel north latitude and did not allow the United States to cross this line. So the North Vietnamese moved a large number of factories near the Sino-Vietnamese border, hoping to rely on China's deterrence to protect them from the United States.
Therefore, after the outbreak of the self-defense counterattack against Vietnam, the rear area of Vietnam suddenly became a battlefield. The industrial facilities throughout Northern Vietnam were smashed to smithereens. When our country withdrew, it demolished all the industrial facilities that had not been destroyed, so that North Vietnam completely lost its industrial capacity. Until now, China's demolition of factories in northern Vietnam still has a residual impact. At present, Vietnam is in the situation of many factories in the south and fast economic development, but there are no factories in the north and the economic development rate is slow.
Cross the Poor Qi River
Finally, cross the Qiqian River. The Chi Pian River is the dividing line of Lang Son, the last barrier in Hanoi, the capital of Vietnam, and the new urban area of Lang Son is south of the Chi Pian River, and the old town of Lang Son is north of the Ki Khan River. After our country crossed the Qi Phuong River, it meant that All Lang Shan was lost, and the last barrier in Hanoi, the capital of Vietnam, disappeared.
After fighting the Qiqian River, the Soviet Union soberly realized that Vietnam could not resist China at all, and it was unrealistic for Vietnam to assist the Soviet Union in dealing with China. The Soviets then abandoned Vietnam and gradually reduced their support for Vietnam. Vietnam itself is mountainous, it is not easy to develop, after the Soviet Union reduced support, Vietnam to turn around more and more difficult.
Of course, the most important thing is the decade-long battle between China and Vietnam. In this war, Vietnam had to resist China with national strength, and at that time the scope of Vietnamese conscription had been revised to 14 to 45 years old, completely abandoning education and economic development. In these 10 years, Vietnam has not had the opportunity to develop its economy. By the end of the Two Hills Round War, Vietnam had lost its window of economic development.
