Chapter 2 of The People’s Republic under Mao, 1949–1976: “Korea and the Campaigns”
North Korea invaded the South in June 1950, and on 19 October Chinese troops crossed the Yalu as the “Chinese People’s Volunteers”. They pushed UN forces back to near the 38th parallel at a cost of about 200,000 to 400,000 Chinese dead, while the war gave the Party reason to destroy its remaining opponents at home.

SHORT EXPLANATION
North Korea’s invasion of the South in June 1950 had Stalin’s approval and Mao’s agreement. Mao expected a northern victory. Instead, American-led United Nations forces crossed the 38th parallel, the line dividing the Koreas, and by October approached the Yalu River on China’s border. On 19 October Chinese troops crossed into Korea under the name “Chinese People’s Volunteers”, allowing Beijing to fight the world’s strongest power without a formal declaration of war.
The Chinese pushed the UN forces back toward the war’s starting line, but the fighting cost China about 200,000 to 400,000 dead. The July 1953 armistice left Korea divided; it was a ceasefire, never turned into a peace treaty. China had fought the United States to a standstill, and the new state gained prestige from that result even though it had not won the war.
The war also changed politics inside China. The Communist Party, now the sole ruler, could present the destruction of remaining opponents as a national defense. It mobilized people in campaigns, organized drives against named enemies resembling emergencies in which ordinary rules were suspended. The Campaign to Suppress Counter-revolutionaries began in October 1950 against people accused of serving the old regime or foreign allies. Stadiums became places for mass trials, and the Party’s own count recorded 712,000 executions.
The Three-Anti campaign of 1951–52 attacked corruption, waste and bureaucracy among officials; the Five-Anti campaign of 1952 turned on private businessmen whom the 1949 coalition had promised to protect. Follow the arrows on the map to see the armies advance and retreat in Korea; the dotted line shows the armistice, while provinces turn solid red as land reform is completed. By 1953 the Party faced no organized opposition anywhere in China. Campaigns, with their quotas, accusations and confessions, had become a normal way to govern.
The full story
The Korean War began with a northern invasion, but by autumn 1950 the forces approaching China were American-led. The UN landing at Incheon in September reversed the course of the fighting. UN troops crossed the 38th parallel and advanced toward the Yalu, the river separating Korea from Manchuria, China’s industrial northeast. Premier and foreign minister Zhou Enlai warned through the Indian ambassador that China would act; Washington dismissed the warning as bluff. Mao judged the danger of remaining outside the war greater than the danger of entering it.
Lin Biao declined the command, and Mao chose the civil-war veteran Peng Dehuai. On the night of 19 October the Chinese People’s Volunteers crossed at Andong. Their intervention surprised the world’s strongest army: by late November they had trapped American columns at the Chosin Reservoir and along the Chongchon River, and in January 1951 they retook Seoul. That was the high point of their advance.
Holding the line became a different task from driving the UN forces back. Chinese armies lacked artillery, trucks and air cover; their attacks in waves met devastating American firepower. Mao Anying, Mao’s own son, was killed in an air raid on Peng’s headquarters in November 1950. By mid-1951 the front had settled near the 38th parallel. Talks continued for two more years, held up above all by prisoners: about 14,000 of the 21,000 Chinese captives refused repatriation and chose Taiwan instead.
The armistice was signed on 27 July 1953 at Panmunjom, a village on the front. The line on the map shows a divided Korea. Beijing’s official count of Chinese dead rose from 183,108 in 2010 to 197,653 in 2020; other estimates reach about 400,000. China had not won, but the ability to hold the United States to a standstill brought the new government enormous prestige.
The fighting abroad gave urgency to a campaign already beginning at home. A campaign mobilized the country against a named enemy, much as a wartime emergency drive might suspend ordinary rules. The “Double Tenth” directive of 10 October 1950 called for a hunt for “counter-revolutionaries”. The label covered former Nationalist officials, bandits, alleged saboteurs and leaders of secret societies such as Shanghai’s Green Gang. Mao suggested executions at about one per thousand people. Public trials filled stadiums and went out over the radio; a 1954 report counted 712,000 executed, 1.29 million imprisoned and 1.2 million placed under police watch.
Other campaigns carried the method into government offices and private firms. The Three-Anti campaign purged officials for corruption; the Five-Anti campaign named five “poisons”, including bribery and tax evasion, and used fines and humiliation against businessmen. Hundreds of Shanghai owners took their own lives, and private firms came to depend on the state. Quotas, mass meetings and forced confessions could now be used in peace as well as war.
FULL EXPLANATION
Why did Mao send troops to Korea?
The approach to the Yalu gave Beijing a compelling security reason to intervene. Allen Whiting’s influential 1960 account put that reason at the center: American troops threatened Manchuria’s factories and power stations, and China acted after its warnings were ignored. Documents released in China and Russia after the Cold War added another dimension. In China’s Road to the Korean War (1994), Chen Jian shows Mao preparing forces in Manchuria from the summer of 1950 and pressing a reluctant Politburo to fight. Mao believed revolutionary China needed to confront American power somewhere; he also saw war as a way to rally the country behind the new state. Stalin had approved Kim Il-sung’s invasion and urged Chinese intervention, but hesitated over the air cover he had promised. The Volunteers entered without it. Most historians now combine the explanations: the security threat was real, while Mao chose to fight despite hesitation among other leaders and valued the war’s effects inside China as well as in Korea.
The campaign as a way of governing
A campaign, or yundong, was a technique of rule with a recognizable sequence. The Party named a target and assigned local quotas for finding enemies. Work teams called meetings, organized accusations and extracted confessions. At the end, a “rectification” could blame local officials for excesses. Julia Strauss calls this “paternalist terror”: the center demanded results, cadres competed to deliver them, and the center then appeared as the source of moderation. Yang Kuisong’s study of Party documents shows Mao setting execution ratios in early 1951 and slowing the killing in late April when it had run ahead of plan; Yang argues that the real total exceeded the official 712,000. The system could produce obedience, but it was badly equipped to correct mistakes. For a cadre judged by the number of enemies found, exceeding the target could seem safer than restraint.
How the Five-Anti campaign broke private business
Private businessmen had been promised a place in the 1949 Common Program. The Five-Anti campaign changed what that place was worth. In 1952 firms were investigated for bribery, tax evasion, theft of state property, cheating on government contracts and stealing state economic secrets. Employees were encouraged to denounce their bosses, and owners were classified from “law-abiding” to “completely lawless”. Most were found guilty of something. Fines could be so heavy that working capital passed to the state; many owners were publicly humiliated, and hundreds in Shanghai killed themselves in the first months of 1952. The firms remained private on paper, but state orders, credit and approval now sustained them. When the remaining enterprises became “joint state-private” companies in January 1956, almost no resistance followed. The earlier campaign had already deprived their owners of much of their independence.
Key places on the map
On this day
Why it happened
Kim Il-sung’s war and Stalin’s consent. Kim Il-sung secured Stalin’s approval in April 1950 and Mao’s acceptance during a visit to Beijing in May. North Korea invaded the South on 25 June. Mao expected the North to win quickly and intended to invade Taiwan that year. Instead the United States sent the Seventh Fleet into the Taiwan Strait and an army to Korea. The Korean civil war had brought American forces close to China.
MacArthur crossed the parallel. The UN landing at Incheon on 15 September 1950 broke the North Korean army. Pursuit across the 38th parallel in early October put American troops on the road to the Yalu. Zhou Enlai sent a warning through the Indian ambassador, K. M. Panikkar, but Washington treated it as bluff. General MacArthur assured President Truman that China would either stay out or be crushed if it intervened. The error helped determine the next three years of war.
Mao wanted the confrontation. Mao had reasons to fight beyond the immediate border threat. Archival research shows his belief that confronting American power would bring revolutionary China respect abroad and loyalty at home. He also remembered the Korean soldiers who had fought in China’s civil war and feared that a hostile Korea would threaten the industrial northeast. Much of the Politburo hesitated in early October, but Mao overruled it; his authority carried the decision.
A state that felt surrounded by enemies. In 1950 the new government faced Nationalist units and bandit gangs in the southwest, rural secret societies and agents sent from Taiwan. It claimed that it had to suppress about a million “bandits” in its first years. War with the United States made it easier to portray these distinct threats as parts of a foreign plot. Suspicion could become evidence, and a security operation could become a national campaign.
THE TURNING POINT
The Yalu, 19 October 1950. The Double Tenth directive preceded the Yalu crossing by nine days. Together they show how quickly consolidation gave way to an enduring emergency. The Party had still been courting businessmen, intellectuals and foreign governments; now China fought the United States, faced an embargo on Western trade and depended on Soviet weapons and loans. War abroad strengthened the government’s demand for total loyalty at home. The campaign became a normal instrument of rule.
What it changed
A general with the prestige to object. Peng Dehuai emerged from Korea as China’s most respected soldier, credited with holding off the Americans with a peasant army. That standing helped give him the confidence to write Mao a frank letter about the Great Leap Forward in 1959. It also helps explain why Mao regarded his criticism as dangerous. The war had elevated a soldier whom the Leap would destroy.
The campaign becomes the method of rule. The campaigns of 1950–53 supplied a set of tools used again against intellectuals in 1957, peasants in 1958 and the Party itself in 1966: quotas, mass meetings, forced confessions and subsequent “corrections” of excess. Officials learned that exceeding a target could be safe while caution could look like sympathy for the enemy. Campaigns consequently ran hotter than the center had planned, and officials who had obeyed were blamed afterward.
Locked into the Soviet camp. An American-led trade embargo from 1951 restricted China’s choices, while the war made it dependent on Soviet loans, advisers and weapons that had to be paid for. The First Five-Year Plan, launched in 1953, used Soviet equipment and followed the Soviet model. Mao’s political preference for that model, declared in 1949, had become a dependence that shaped industrialization.
Taiwan behind an American shield. Truman’s fleet entered the Taiwan Strait in June 1950 and never left; in 1954 Washington signed a defense treaty with the Nationalists. The Korean War had put Mao’s chance of completing the civil war out of reach. Beijing tested the American commitment by shelling offshore islands in 1954 and 1958. Taiwan remained central to Chinese foreign policy through Nixon’s 1972 visit and beyond.
DISCUSSION QUESTION — Did the Korean War strengthen or weaken Mao’s new state?
The war strengthened the regime’s authority, but its costs fell heavily on China and its people. About 200,000 to 400,000 Chinese soldiers died, much of the budget went to the war, Soviet weapons had to be paid for, and the American fleet put Taiwan out of reach. Soldiers and families bore the cost of a decision that some historians emphasize was a gamble. At home, however, the Party could present campaigns against counter-revolutionaries, corrupt officials and businessmen as patriotic defense. Donations and recruits came from every province, while a peasant army’s stand against the United States gave the state prestige no Chinese government had enjoyed since the Opium Wars. Chen Jian argues that Mao had sought domestic mobilization from the outset. By the measure of state power, China emerged harder, more unified and more feared; its society emerged poorer, more isolated and more afraid. War can strengthen a new authoritarian regime by making dissent appear to be treason.
An interesting fact
A national donation drive asked factories, villages and schools to raise money to “buy” aircraft and guns for the Korean front. Its most famous donor was Chang Xiangyu, a Henan opera star. During six months in 1951 she toured China in a play about the woman warrior Hua Mulan and gave the proceeds for a MiG-15 fighter. Her troupe’s name was painted on its nose; the aircraft now stands in the China Aviation Museum north of Beijing. Such drives recurred in later campaigns, making patriotism a public act measurable by the amount given.
