The situation between the two nations was complicated by the 1957–1959 uprising by Tibetans against Chinese rule. Refugees poured across the Indian border, and the Indian public was outraged. Any compromise with China on the border issue became impossible. Similarly, China was offended that India had given political asylum to the Dalai Lama when he fled across the border in March 1959. In late 1959, there were shots fired between border patrols operating along both the ill-defined McMahon Line and in the Aksai Chin.
Territorial Dispute: The situation along the Sino-Indian frontier continued to worsen. In late July (1959), an Indian reconnaissance patrol was blocked, "apprehended," and eventually expelled after three weeks in custody at the hands of a larger Chinese force near Khurnak Fort in Aksai Chin. ... Circumstances worsened further in October 1959, when a major class at Kongka Pass in eastern Ladakh led to nine dead and ten captured Indian border personnel, making it by far the most serious Sino-Indian class since India's independence.
