The War to Resist US Aggression and Aid Korea, also known as the Movement to Resist US Aggression and Aid Korea or the War to Resist US Aggression and Aid Korea, was part of the Korean War that broke out in the early 50s of the 20th century, which only refers to the stage when the Chinese People's Volunteers participated in the war, and also includes the mass movement of the Chinese people to support the Korean people in resisting US aggression.
Cold War background: The War to Resist US Aggression and Aid Korea took place during the Cold War, and the international confrontation between the capitalist camp led by the United States and the socialist camp with the Soviet Union as the core was formed. The Korean War was an important event in the Cold War, involving a confrontation between the two camps.
The situation on the Korean Peninsula: Before the outbreak of the Korean War, the Korean Peninsula was in a state of confrontation between the North and the South. There are huge differences between North and South Korea in terms of ideology, political system and economic model, and tensions between the North and the South have persisted. North Korea is trying to reunify the peninsula by force, while South Korea is supported by the United States.
The course of the war: At the beginning of the Korean War, the North Korean army quickly occupied most of the South Korean territory, but the joint was carried out, and the North and South fronts gradually stabilized. Subsequently, China intervened in the war, supported North Korea, and launched an offensive in the northern part of the Korean Peninsula. The war became protracted and brutal, with huge losses on both sides.
International Engagement: The Korean War was an important event during the Cold War and involved many countries. In addition to North and South Korea, countries such as the United States, China, and the Soviet Union participated. The war became a direct conflict between the two camps of the United States, the United States and the Soviet Union in the Cold War, and it was also the first time that the United Nations responded to a conflict with collective action.
China sent troops: On July 10, 1950, the "Chinese People's Movement Committee Against US Aggression against Taiwan and Korea" was established, and the Movement to Resist US Aggression and Aid Korea began. In October, the Chinese People's Volunteers went to fight in Korea, kicking off the War to Resist US Aggression and Aid Korea. In the War to Resist US Aggression and Aid Korea, the Chinese Volunteers received the full support of the entire PLA and the Chinese people, and the cooperation of the socialist camp headed by the Soviet Union. Ignoring repeated warnings from China, the United States crossed the 38th parallel on October 1 and occupied Pyongyang on the 19th, in an attempt to quickly occupy the whole of Korea, and openly claimed: "In history, the Yalu River is not an insurmountable obstacle that divides China and North Korea." At the same time, US planes have repeatedly intruded into China's airspace and bombed the Dandong area, and the war is about to burn to the Yalu River. On October 8, 1950, North Korea** requested China's military assistance. At the request of the DPRK, China made the decision to "resist US aggression and aid Korea and defend the homeland and defend the country" and quickly formed the Chinese People's Volunteer Army to enter the Korean War.
Personally, I think that in addition to responding to the request of the DPRK, China has the following considerations:
Geopolitical considerations: After the outbreak of the Korean War, the United States and the United Nations decided to step in to support South Korea. Considering the impact of the war on the stability of its borders, as well as the threat of U.S. forces proximity to China's northeast and east coasts, China chose to step in to protect ***
Ideological conflicts: *The Chinese Communist Party (CCP) led by the Chinese Communist Party has clear differences with the ideological and political positions of the United States. The U.S. involvement in the Korean War was seen by China as a challenge to communism, so China chose to support North Korea and the Soviet Union as a way to resist the U.S. and capitalism.
International status and reputation: Participating in the War to Resist US Aggression and Aid Korea has enhanced China's status and influence on the world stage. The war made China the vanguard of resistance to American aggression and expanded its influence around the world.
Protect the interests of the socialist camp: Participation in the Korean War was to protect the interests of the socialist camp. The Soviet Union was a supporter in the Korean War, and China was involved in it in order to preserve common ideology and national interests.
Overall, China's involvement in the Korean War was motivated by a number of factors, including ideological, geopolitical, and domestic stability. The war also became one of the important conflicts between China and the United States during the Cold War, affecting the political landscape and international relations of the entire Asian region.
