In which year did China attack India?

Border disputes and conflicts have shaped international relations throughout history. The question refers to a significant military confrontation between two Asian giants. The correct answer is 1962.

• The Sino-Indian War, a brief but intense border conflict between China and India, occurred in 1962. The war was primarily fought over disputed territories in Aksai Chin and what was then the North-East Frontier Agency (NEFA), now Arunachal Pradesh. China launched a large-scale offensive on October 20, 1962, and declared a unilateral ceasefire a month later.
• 1981 did not witness a major military conflict between China and India.
• The war concluded in 1962, so 1963 is incorrect for the year of the attack.
• 1971 is notable for the Indo-Pakistani War, which led to the creation of Bangladesh, not a major conflict with China.
