The year 1965 is often remembered in Indian history for the war with Pakistan, but during the same period, India also faced rising tensions with China. Although there was no large-scale war like in 1962, several border skirmishes and political classes occurred between the two nations, especially in the regions of Sikkim and the eastern Himalayas.
Background
After the 1962 Sino-Indian War, relations between India and China remained extremely strained. China continued to strengthen its position along the Himalayan borders, while India focused on rebuilding its military and improving its defense infrastructure. By 1965, both nations had unresolved border disputes,particularly in the areas of Aksai Chin (in Ladakh) and the McMahon Line (in Arunachal Pradesh).
Chinese Ultimatum
During the height of the Indo-Pak war (September 1965), China accused India of trespassing into Chinese territory and demanded that India dismantle certain military posts. China even gave India an ultimatum to withdraw its troops from the claimed area. However, India stood firm and refused to comply with China’s withdraw its troops from the claimed area.

Outcom
The situation eventually de-escalated without leading to a full-scale war. China did not intervene militarily in support of Pakistan, despite being its close ally. This showed that India’s diplomatic and military stance had strengthened considerably since the 1962 war. The incident also highlighted the importance of India’s defense preparedness and its ability to manage threats on two fronts.
Aftermath and Significance
The 1965 India-China tensions marked a new phase in their relationship. India learned the importance of vigilance along the northern borders and began to further modernize its armed forces. Although the conflict did not result in major casualties, it reminded both nations that the border issue remained unresolved—a factor that continues to influence India-China relations even today.
