1962 border war india and china?

The 1962 border war between India and China, also known as the Sino-Indian War, was primarily rooted in territorial disputes over the Aksai Chin region and Arunachal Pradesh. Tensions escalated when China launched a surprise offensive in October 1962, quickly overwhelming Indian forces. The conflict lasted about a month, resulting in a significant Chinese victory and the establishment of the McMahon Line as a de facto border, although disputes over the region remain unresolved. The war had lasting impacts on India-China relations and heightened India's focus on military modernization.
