How much damage did the self-defense counterattack against Vietnam cause to Vietnam? Why doesn't China dare to report it?
China's vigorous aid to Vietnam, but its eventual turn against Vietnam, is the result of a combination of complex national interests, geopolitics, and special inter-party and state relations among socialist countries. First, the relationship between China and Vietnam is deeply rooted in the relationship between the two nation-states, entangled in thousands of years of historical grievances; in the past thousand years, China has ruled Vietnam for a long time, and later made Vietnam a vassal, and there have been many wars between the two sides. In terms of national nature, Vietnam is actually afraid and hated China. The threat from the north has always been a major problem for the Vietnamese. Geopolitically, the national strength of China and Vietnam is very different, and China's behemoth is pressed on Vietnam's back, lying on the edge of the bed, how to rest assured! Even today, in the 21st century, Vietnam's vigilance against its "northern neighbor" has not been relaxed.

Since 1960, Sino-Soviet relations have been in a state of continuous hostility, in March 1969, the Sino-Soviet conflict broke out on Treasure Island, and Sino-US relations began to improve at this time, In 1971 Sino-US table tennis diplomacy, in 1972, Nixon's visit to China, Sino-US relations entered a new historical period. These situations were undoubtedly not good news for Vietnam, which was hostile to the United States and close to the Soviet Union at the time, and may mean that China will reduce or even end its support and assistance to Vietnam. Dissatisfied, Vietnam turned to the Soviet Union and began to see China as "the most dangerous and direct enemy." Another reason is that China supported Cambodia at that time, and they regarded Cambodia as an enemy, so they regarded China as an enemy. For China at that time, Vietnam encroached on the Sino-Vietnamese border in the south, constantly made armed provocations, and invaded China's ally Cambodia at the end of 1978, which was naked regional hegemonism and a serious threat to China's peripheral security. Therefore, on July 3, 1978, the Chinese government sent a note to the Vietnamese government to stop aiding Vietnam. At 4:30 a.m. on February 17, 1979, the War of Punishment for Vietnam began. This war is generally known as the Sino-Vietnamese border self-defense counterattack operation or the Vietnamese self-defense counterattack operation, also known as the vietnamese self-defense counterattack war, in Vietnam, known as the 1979 Northern Border War or the Vietnam-China Border War.
How much damage did the self-defense counterattack against Vietnam cause to Vietnam? Why doesn't China dare to report it? After ten years of border operations, China struck a blow to Vietnam's confidence that had swelled since the victory in the Vietnam War, stabilized China's southwest frontier, and at the same time promoted the peace situation in Southeast Asia, dividing the front into Two Operational Directions of China's Western Front Yunnan Province and the Eastern Front Guangxi Zhuang Autonomous Region, by March 4, 1979, the Eastern Front Chinese troops burst into Vietnam with a depth of 50-100 kilometers, successively capturing the two provincial capitals of GaoPing and Lang Son, as well as Ha Quang, Cha Ling, Guang Ho, Ha An, Tong Nong, Shi An, Chongqing, Changding, Thlang, Gao Lu, Lu Ping has 11 county seats and Tongdeng Town. A total of 40,671 enemy personnel were annihilated, more than 340 Vietnamese artillery pieces, 45 tanks and armored vehicles, and more than 480 cars were destroyed, more than 840 artillery pieces, more than 11,000 guns of various kinds (poles and equipment) and a large number of military materials were captured, and at the same time, devastating blows and destruction were carried out on military and civilian facilities in the northern Part of the Eastern Front, and cattle were killed or robbed: 157,000 of the total 260,000 heads were killed or robbed, accounting for 60 percent. Pigs killed or snatched: 244,000 of the total 35,000 were killed or robbed, or 80 percent.
In fact, during the Vietnam War of Resistance Against France, China was the first to recognize the Democratic Republic of Vietnam and establish diplomatic relations with it. China was also the only country in Indochina to trade with Vietnam before the peaceful restoration of peace. In Sino-Vietnamese trade, China has tried its best to buy the local specialties that Vietnam needs to export, and China has tried its best to satisfy the goods that Vietnam needs to import, which has made tremendous contributions to stabilizing the livelihood of the Vietnamese people, smashing the French economic blockade of the Liberated Areas, and promoting the development of the productive forces in the Liberated Areas of Northern Vietnam. Shortly after the founding of New China, China, in the face of waste and many difficulties, cut back on food and clothing, and provided weapons, ammunition, grain, oil, and other assistance to Vietnam in the War of Resistance Against France. Unexpectedly, I raised a white-eyed wolf. For such a white-eyed wolf, of course, we must teach a good lesson
