The Chinese invasion, 1962

Two major developments strained India-China relations in the 1950s, culminating in the 1962 war. First, China's annexation of Tibet in 1950 removed a historical buffer zone between the two countries. India initially did not openly oppose this but grew uneasy as China suppressed Tibetan culture and autonomy. The Dalai Lama's asylum in India in 1959 further aggravated tensions, with China accusing India of harboring anti-China activities.

Second, a boundary dispute emerged over two main areas: Aksai Chin in Ladakh and Arunachal Pradesh (then NEFA). China claimed these territories as part of its own, rejecting colonial-era boundary agreements that India recognized. Between 1957 and 1959, China occupied Aksai Chin and constructed a strategic road.

Despite extensive correspondence and discussions between leaders, including Nehru and Mao Zedong, the disputes remained unresolved. Several border skirmishes occurred.

In October 1962, while global attention was focused on the Cuban Missile Crisis, China launched a swift and massive invasion on both disputed fronts. The first attack lasted a week, with Chinese forces capturing key areas in Arunachal Pradesh. A second wave followed in November. Indian forces managed to block advances in Ladakh but were pushed back near the Assam plains in the east.

China declared a unilateral ceasefire and withdrew troops to pre-war positions. The war was a severe blow to India's image domestically and internationally. India sought military assistance from the US and UK, while the Soviet Union remained neutral.

The war led to national humiliation but also strengthened Indian nationalism. Several top army commanders resigned or were retired. Defence Minister V. Krishna Menon, a close associate of Nehru, resigned. Nehru faced severe criticism for his misjudgment of Chinese intentions and lack of military preparedness. A no-confidence motion was moved against his government, and the Congress lost key by-elections, signaling a shift in political mood.
