“Valiant, high spirited, crossing the Yalu River…” 70 years ago, the Chinese people’s Volunteer Army, holding high the banner of resisting US aggression and aiding Korea and defending the country, went to the Korean battlefield and fought side by side with the Korean army and people. In an interview, many experts said that the war of resisting U.S. aggression and aiding Korea is a just war to safeguard peace and resist aggression, and has made great contributions to world peace and human progress. In June 1950, the Korean civil war broke out, and the U.S. government gathered the “United Nations forces” to intervene in armed forces, and sent the seventh fleet of the navy to invade the Taiwan Strait of China. After that, the invading US troops crossed the 38th line and went straight to Yalu River, and sent planes to bomb the northeast border of China, which directly threatened the national security of new China. < / P > < p > “making a major strategic decision to resist U.S. aggression and aid North Korea and protect the country is not only based on China’s security, but also from the need to save North Korea in times of crisis, and to maintain peace in Asia and the world, reflecting a high degree of internationalism.” Ding Wei, a researcher at the Academy of Military Sciences, said. After nine months of hard war, the Chinese people fought together in the bloody war. Experts said that the victory of the war of resistance against U.S. aggression and aid Korea has effectively hit the arrogant momentum of US imperialism’s aggression and expansion, greatly inspired the just cause of the oppressed nations and people in the world to strive for national independence and people’s liberation, and China’s international status has improved unprecedentedly. < / P > < p > “the war of resistance against U.S. aggression and aid Korea not only forced the adversaries to sign the armistice agreement, but also drew a” red line “for the aggressor’s behavior and set up the rules for safeguarding peace. This “red line” is that whoever wants to solve any Oriental problem directly related to China arbitrarily must be beaten to pieces. This “red line” drawn with the blood of martyrs is still of practical significance and influence. ” Shao Zhiyong, Professor of National Security College of National Defense University, said. Yin Zhengda, a professor at the school of national security of National Defense University, said that the war of resisting US aggression and aiding Korea carried out by the Chinese people’s Volunteer Army and the Chinese people was a just feat of fighting hegemonism and power politics, safeguarding the UN Charter and the basic norms of international relations. It has won the sympathy, support and assistance of peace loving countries and people all over the world, and to China, Northeast Asia and even the whole world The world has a profound impact. He said that the war of resistance against U.S. aggression and aid Korea has created a strong atmosphere in which the Chinese people and the Chinese nation do not believe in evil and are not afraid of ghosts, completely smashed the US attempt to occupy the Korean Peninsula and contain new China, maintained the security of China’s northeast border, and ensured the long-term stability of the strategic pattern of the Korean Peninsula and even northeast Asia. < / P > < p > “the victory of this war has safeguarded the security of the Democratic People’s Republic of Korea and the newly born people’s Republic of China, disrupted the deployment of imperialist expansion of sphere of influence, deterred the impulse of invading other countries’ territory and interfering in other countries’ internal affairs, and highlighted the rise of new China, an important force for maintaining world peace, and profoundly influenced and changed the Second World Congress After the end of the war, the political pattern in Asia and the world has maintained peace in Asia and the world. ” Yin Zhengda said. The U.S. armed forces use all advanced weapons and ground forces are mechanized, while the Chinese people’s Volunteer Army basically relies on infantry and a small number of artillery, and its weaponry is quite backward. Yuan Ye, a professor at the school of national security of National Defense University, believes that winning the war under the condition of great disparity between the enemy and ourselves has created an example of using the weak to win the strong and realizing the strategic goal of “seeking peace through war”. < / P > < p > “the Chinese people dare to send troops to North Korea, dare to fight with the United States, the world’s largest power, and dare to fight against the” United Nations army “, which embodies the firm determination and strong strength of the Chinese nation to resist violence and maintain world peace. This was a great encouragement to the oppressed nations and people at that time, and greatly enhanced their strong determination to defend their own development path. ” Yuan Ye said.
