1967: In Sikkim, India pushes China back
- Tensions came to a head again in 1967 along two mountain passes, Nathu La and Cho La, that connected Sikkim — then a kingdom and a protectorate of India — and China’s Tibet Autonomous Region.
- A scuffle broke out when Indian troops began laying barbed wire along what they recognized as the border.
- The scuffles soon escalated when a Chinese military unit began firing artillery shells at the Indians.
- In the ensuing conflict, more than 150 Indians and 340 Chinese were killed.
- The clashes in September and October 1967 in those passes would later be considered the second all-out war between China and India.
- But India prevailed, destroying Chinese fortifications in Nathu La and pushing them farther back into their territory near Cho La.
- The change in positions, however, meant that China and India each had different and conflicting ideas about the location of the Line of Actual Control.
- The fighting was the last time that troops on either side would be killed. — until the skirmishes in the Galwan Valley on Tuesday.
