The border problems between India and China were the result of the independence of India from the United Kingdom. When the British left India in 1947, India proved unwilling to prevent China's reoccupation of Tibet. Indian protests at the loss of its rights there and later at the Chinese crushing of the 1959 Tibetan rebellion, as well as its granting asylum to the Dalai Lama, infuriated the Chinese but did not check their plans for the area. In the 1950's it became clear that China planned to push into India's border with India.
In 1954, China made its first incursion into Indian territory. This would be followed up in 1956-7.
The Sino-Indian War, which occurred in 1962, ended with a unilateral ceasefire declared by China on November 21, 1962. Following intense fighting, China gained control over disputed territories in the Aksai Chin region and retreated from areas in Arunachal Pradesh after establishing its positions. The conflict highlighted deep-seated territorial disputes and led to a significant shift in Sino-Indian relations, with both countries remaining cautious and distrustful of each other in subsequent years. The war officially concluded without a formal peace treaty, leaving lingering tensions over border issues.

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.
