What this dot point is asking
NESA expects you to outline Mao Zedong's foreign policy, including the alliance with the USSR, its rupture, and the strategic opening to the United States in 1971 to 1972. Strong answers integrate the ideological, military, and diplomatic dimensions.
The answer
The lean to one side, 1949
Mao's June 1949 essay "On the People's Democratic Dictatorship" (Lun renmin minzhu zhuanzheng) committed the PRC to "leaning to one side" (yibian dao) of the Soviet Union. The June essay foreclosed a Titoist or neutralist position before the proclamation of the PRC on 1 October 1949. Mao's December 1949 to February 1950 trip to Moscow produced the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance (14 February 1950), a 30-year alliance with a USD 300 million loan over five years and the 156 First Five-Year Plan capital projects.
The Korean War and the high tide of the alliance
The Korean War (1950 to 1953) bound the PRC to the Soviet weapons system. The PRC repaid the entire Korean War debt to the USSR. The mid-1950s were the peak of the alliance: Soviet engineers built the First Five-Year Plan; the 1957 Moscow Agreement on Defence New Technology provided for a Soviet prototype atomic bomb to be delivered to China.
Sources of the split
The split developed from 1956 to 1960 across several axes:
- De-Stalinisation. Khrushchev's secret speech of 25 February 1956 denounced Stalin. Mao, who had defended Stalin within strict limits, accused Khrushchev of repudiating the international communist tradition.
- Peaceful coexistence. Khrushchev's 20th Congress doctrine of "peaceful coexistence" with the capitalist world struck Mao as revisionism. Mao's "the East wind prevails over the West wind" of November 1957 was a counter-doctrine.
- Atomic weapons. The 1957 prototype agreement was revoked by the Soviets on 20 June 1959. Mao thereafter accelerated the Two Bombs and One Satellite (Liang dan yi xing) programme.
- The 1958 Taiwan Strait Crisis. Mao shelled Quemoy and Matsu without consulting Moscow; Khrushchev resented the strain on Soviet US deterrence.
- The Great Leap. The Communes and the "transition to communism" were treated by Soviet doctrinaires as deviation.
- Personal contempt. Mao and Khrushchev disliked each other. Khrushchev's 1958 and 1959 visits to Beijing were diplomatic disasters.
- The Sino-Indian dispute. Soviet "neutrality" between the PRC and India in 1959 and after was treated as betrayal.
The rupture, 1960 to 1963
Khrushchev withdrew about 1,400 Soviet advisers from China in July to August 1960, tearing up around 343 contracts and 257 scientific projects. The Bucharest Conference of June 1960 and the Moscow Conference of 81 communist parties in November 1960 saw public polemics. The "21st Anniversary of Lenin's Birth" Renmin Ribao editorial of 16 April 1960, "Long Live Leninism", was the open ideological attack.
From 1963 the CCP published the Nine Commentaries (Jiu Ping) on the open letter of the CPSU CC, the most sustained polemic of the Cold War. The split became public knowledge.
The Sino-Indian War, 1962
A short border war over Aksai Chin (in the west) and the McMahon Line (in the east) ran from 20 October to 21 November 1962. PLA forces under Zhang Guohua drove Indian forces from disputed territory and then unilaterally withdrew, retaining Aksai Chin. The war embarrassed the Soviets, who had supplied India with MiG aircraft.
Two Bombs and One Satellite
China's first atomic bomb test at Lop Nur in Xinjiang took place on 16 October 1964, designed by Qian Sanqiang, Deng Jiaxian, and Yu Min. The first thermonuclear test (Test 6) was on 17 June 1967. The first satellite, Dong Fang Hong 1, was launched on 24 April 1970. The Dong Feng-5 ICBM (1980) gave the PRC strategic deterrence.
Zhenbao Island clashes, 1969
The border dispute escalated in 1969. On 2 March 1969 PLA frontier troops ambushed Soviet forces on Zhenbao Island (Russian: Damansky Island) on the Ussuri River, killing about 32. The Soviets counter-attacked on 15 March 1969 with armour and artillery, with casualties on both sides. A larger clash followed in August 1969 in Xinjiang. Soviet hints through the Polish channel and via diplomats in Washington of a potential preventive nuclear strike on Chinese facilities at Lop Nur forced Mao to seek a strategic counterweight.
Opening to the United States
Mao's reading of the Sino-Soviet danger, parallel to Nixon's reading of the Vietnam War as needing Chinese leverage, produced rapprochement. The signals included:
- The Polish channel and the Warsaw ambassadorial talks (resumed 1970).
- Mao's 1 October 1970 Tiananmen photograph with Edgar Snow.
- "Ping-pong diplomacy" in April 1971 when the US table tennis team toured China.
- Henry Kissinger's secret trip to Beijing via Pakistan, 9 to 11 July 1971.
- The PRC taking the China seat at the UN on 25 October 1971 under General Assembly Resolution 2758.
- Nixon's visit, 21 to 28 February 1972. Nixon met Mao on 21 February in Mao's study. The Shanghai Communique of 27 February 1972 acknowledged "one China" without specifying which Beijing.
The Three Worlds Theory, formulated by Mao in talks with Zambian President Kenneth Kaunda on 22 February 1974, divided the world into First (US and USSR superpowers), Second (developed Europe, Japan), and Third (developing world including China) and justified the US tilt against the Soviet "main enemy".

Historiography
Lorenz Luthi (The Sino-Soviet Split, 2008) gave the canonical archival account from Chinese, Russian, and East European sources.
Sergey Radchenko (Two Suns in the Heavens, 2009) emphasised the personal antagonism between Khrushchev and Mao.
Margaret MacMillan (Nixon and Mao, 2007) gave the standard popular account of the 1972 opening.
Chen Jian (Mao's China and the Cold War, 2001) treated PRC foreign policy as driven by ideology and revolutionary identity, not by Realpolitik alone.
Odd Arne Westad (Restless Empire, 2012) treated Mao's foreign policy in the long arc of Chinese modern history.
Niu Jun (From Yan'an to the World, 2005) is the leading Chinese-language account.
Common exam traps
Treating the split as primarily about ideology. State interests (atomic weapons, border, Indian war) were as important as Marxist doctrine.
Misdating the UN seat. 25 October 1971, four months before Nixon's visit.
Forgetting the Soviet danger. Zhenbao 1969 produced the US opening, not the other way around.
In one sentence
Mao Zedong's foreign policy moved from the "lean to one side" of 1949 and the Sino-Soviet Treaty of 14 February 1950, through the ideological and material rupture with Moscow over de-Stalinisation, peaceful coexistence, and nuclear sharing between 1956 and 1960, to the Sino-Indian War of 1962, the first atomic bomb test on 16 October 1964, the Zhenbao Island border clashes of 2 and 15 March 1969 that brought the threat of Soviet preventive strikes, and the strategic pivot to the United States with Kissinger's July 1971 visit, the 25 October 1971 UN seat, and the Nixon visit of 21 to 28 February 1972, justified theoretically by the Three Worlds Theory of February 1974.

A 10-mark "assess" needs a judgement.
Lean to one side, 1949. Mao's June 1949 essay On the People's Democratic Dictatorship committed the PRC to the Soviet camp. The Sino-Soviet Treaty of 14 February 1950 was the alliance.
Sources of split. Khrushchev's 1956 secret speech on Stalin, the dispute over peaceful coexistence, Soviet reluctance to share atomic weapons (the 1957 to 1959 agreements were torn up in June 1959), Soviet "neutrality" in the 1959 to 1962 Sino-Indian dispute, and Khrushchev's withdrawal of about 1,400 Soviet advisers in July 1960.
Public split, 1960 to 1963. The Bucharest Conference of June 1960, the Moscow Conference of November 1960, and the open polemics of 1963 (Nine Commentaries on the Open Letter of the CPSU Central Committee) broke the alliance.
Border conflict. The Zhenbao Island (Damansky) clashes of 2 and 15 March 1969 brought the two states to the brink of nuclear war. Soviet hints of a preventive strike on Chinese nuclear facilities in summer 1969 forced Mao to consider US rapprochement.
Nuclear weapons. China's first atomic bomb test at Lop Nur on 16 October 1964, the hydrogen bomb on 17 June 1967, and the Dong Feng-5 ICBM gave the PRC strategic standing.
Sino-Indian War, 1962. A short border war over Aksai Chin and the McMahon Line. China won militarily and withdrew.
Opening to the United States. Kissinger's secret visit on 9 to 11 July 1971 and Nixon's visit on 21 to 28 February 1972 produced the Shanghai Communique. The PRC took the China seat at the UN on 25 October 1971.
Judgement: the Sino-Soviet split forced Mao to invent the Three Worlds Theory and to pivot to a US tilt. The 1972 opening reshaped the Cold War.
Markers reward 1950 Treaty, 1960 split, 1964 bomb, 1969 Zhenbao, 1971 UN seat, 1972 Nixon.
