Before the confrontation between our country and the former Soviet Union, the Soviet Union could be said to be our big brother, which established complete basic industrial facilities for us, and the Soviet Union was one of the few socialist powers at that time, the same ideology as ours, and our country also borrowed from the revolutionary experience of the Soviet Red Army. But since the 1960s, China's relations with the Soviet Union have begun to deteriorate, and even the Soviet Union has gathered a million troops in the border areas between the two countries, but the result is that they finally dare not wave their troops south.

In 1968, the Soviet Union assembled 40 divisions in the Far East and stationed 12 more in Outer Mongolia, with a total number of more than 700,000 people, all fully equipped. In addition to the army, the Soviet Union also deployed more than 20 divisions of air force and air defense forces, and this huge army gathered on the border was like a precursor to a war, but in the end it did not return. In fact, at that time, if the Soviet Union really wanted to attack our country, the first thing it needed to consider was logistical support and other issues. At that time, the Far East was far from enough to support the logistical supply of a million troops, and the Soviet Union had only one Trans-Siberian Railway to transport war supplies and combatants to the Far East.
And at that time, the Soviet Union and the United States were also in the Cold War period, and if the Soviet Union sent troops to our country at that time, then the United States was likely to take advantage of the void, and then perhaps the Soviet Union would fall into a two-front combat situation, which was undoubtedly unbearable for the Soviet Union. The most important thing is that at that time, China had successfully tested atomic bombs and hydrogen bombs one after another, and also had more than 6 million troops, with a certain military strength.
Moreover, at that time, the biggest enemy of the Soviet Union was still the United States, if the Soviet Union attacked our country, it would certainly not retreat from the whole body, and it would also pay very heavy losses, and the combat strength of the Chinese People's Liberation Army had already been displayed in the War to Resist US Aggression and Aid Korea, and the Soviet Union was also well aware of the combat capabilities of our army.
