Why did China build a road through Aksai Chin in the 1950s?

China constructed a military road through Aksai Chin during the 1950s primarily to establish a strategic connection between Tibet and Xinjiang.1

This project was undertaken because the region, while historically remote and isolated, served as a vital link for Chinese administrative and military logistics between these two territories. The subsequent discovery of this road by India and the resulting diplomatic objections were significant factors that contributed to the Sino-Indian War in 1962. Following the conflict, China maintained control over the area, which remains a point of ongoing territorial contention.1
