IB History Foreign Policy Successes and Failures Under Mao Key Definitions

The force of Chinese troops that intervened in the Korean War in October–November 1950, officially described as "volunteers" to avoid a formal declaration of war against the United States. The CPVA numbered around 300,000 in its initial intervention and eventually exceeded 1 million troops, transforming the military balance in Korea.

President Truman relieved General Douglas MacArthur of command of UN forces in Korea on 11 April 1951, after MacArthur publicly contradicted the administration's policy of limited war. MacArthur had issued an ultimatum to Chinese commanders and written a letter to a Republican congressman calling for the war to be expanded to China. Truman's dismissal affirmed the principle of civilian control of the military and the strategy of fighting a limited war to avoid escalation to a wider conflict.

The boundary between British India and Tibet established at the Simla Convention of 1914, running along the Himalayan watershed. China's PRC government rejected the McMahon Line as an illegitimate colonial imposition, claiming the territory south of it (now the Indian state of Arunachal Pradesh) as Chinese. The dispute over this and other border sections was the primary cause of the 1962 Sino-Indian War.

The "Five Principles of Peaceful Coexistence" agreed between China and India in April 1954: mutual respect for sovereignty and territorial integrity, mutual non-aggression, mutual non-interference in internal affairs, equality and mutual benefit, and peaceful coexistence. The principles were jointly declared by Zhou Enlai and Jawaharlal Nehru and became a foundational text of Afro-Asian neutralism. The principles were ironically undermined by the Sino-Indian War just eight years later.

Ping-pong diplomacy refers to the use of table tennis exchanges to facilitate the rapprochement between the United States and the People's Republic of China in 1971. A US table tennis team competing in Japan was invited to China, becoming the first Americans officially hosted in the PRC since 1949. The exchanges led to Henry Kissinger's secret visit to Beijing in July 1971 and President Nixon's historic visit to China in February 1972.

The Sino-Indian War was a brief but decisive military conflict between China and India over disputed Himalayan border territories in October-November 1962. China launched a two-pronged offensive in the Aksai Chin (western sector) and NEFA (northeastern sector). Indian forces were routed. China declared a unilateral ceasefire in November 1962 and withdrew from some territory, but retained Aksai Chin. The war shattered India's confidence in its military capability and ended Nehru's policy of Sino-Indian friendship.

A 30-year alliance treaty signed between the PRC and the USSR in February 1950, providing China with Soviet economic and technical assistance, a defensive military alliance, and formal Soviet recognition of the PRC. The treaty was a major diplomatic achievement for Mao, though the relationship was unequal: the USSR retained special rights in Manchuria and Xinjiang. The alliance began to deteriorate after 1956 and had effectively collapsed by 1960, when the USSR withdrew all its technical advisers from China.

The breakdown of relations between China and the Soviet Union in the late 1950s and 1960s, caused by ideological disagreements, border disputes, and competition for leadership of the communist world.

Mao Zedong's foreign policy framework, articulated in 1974, which divided the world into three groups: the First World (the US and USSR as imperialist superpowers), the Second World (developed countries under superpower influence), and the Third World (developing nations in Asia, Africa, and Latin America). Mao positioned China as the natural leader of the Third World in opposition to both superpowers, providing a theoretical basis for China's independent foreign policy stance after the Sino-Soviet Split.
