Vietnam is a country even more shameless than Japan, and they do not know how to be grateful at all. Vietnam was originally a part of our China in ancient times, and even after independence, Vietnam has always been a vassal of our China, so there is a deep relationship between the two countries.
After the founding of New China, everything in our country has not yet recovered from the war, but Vietnam is poorer than us, and at that time, our country extended a helping hand to them in the relationship between the two countries, and provided a large amount of economic and military support to Vietnam. After the outbreak of the Vietnam War, our country also risked offending the United States to help them fight against US imperialism, and finally the war was won, and Vietnam successfully completed its reunification, but at this time they turned their faces and did not recognize people, and even began to harass china's border areas continuously, which was simply shameless to the extreme.
When the United States withdrew from Vietnam, it left behind a large number of advanced weapons, and after Vietnam obtained these weapons, it felt that its military strength had been greatly improved, so they did not pay attention to our country at all, and the arrogant Vietnam even claimed to be the third military power besides the United States and the Soviet Union.
Later, after the unanimous decision of the Party Central Committee, in 1979 the People's Liberation Army sent troops to Vietnam, and a counterattack war against Vietnam broke out. However, what chilled our country was that at that time, almost no country in the world supported us, and many countries openly supported Vietnam, including our country's five neighbors, namely the Soviet Union, India, Laos, Afghanistan and Mongolia. We can't say anything about the first four countries, but the Soviet Union is actually Vietnam's most powerful reliance, but Mongolia is the most unacceptable, after all, it has always been part of our China.
Mongolia has always been a part of our country in ancient times, but just when our country was in crisis, Mongolia took advantage of the chaos to declare independence, and there was a Soviet Union behind it, so in the end our country had to recognize the independence of the Soviet Union. After independence, Outer Mongolia was actually a puppet of the Soviet Union, a kind of flattering Soviet Union.
At that time, the relations between our country and the Soviet Union also fell to a freezing point, so the Soviet Union would provoke Vietnam to harass the border areas of our country, and Mongolia openly supported Vietnam in order to please the Soviet Union, and Mongolia, with the support of the Soviet Union, continued to carry out military operations in the northern border areas of our country.
