Nangpa La Pass is visible from the nearby Cho Oyu mountain and its mountaineering base camps. Dozens of foreign mountaineers who were on Cho Oyu witnessed the incident. The mountaineers were able to produce numerous images and videos of the incident, including images of Chinese soldiers escorting the survivors through advanced base camp at Cho Oyu and footage of the People's Armed Police personnel shooting the refugees from great distance. Sergiu Matei, a cameraman at Pro TV, filmed the incident and broadcast live during the incident on Romanian station Pro FM. Matei also helped hide one of the Tibetan refugees for 10 hours before the refugee was able to cross the border into Nepal.
