There was another version of the incident on the LAC with South Block sources saying the Chinese personnel, who were in “civilian clothes”, did not cross the LAC but showed banners that read “Ban all activities to split Tibet”. “On July 6, some 11 Chinese in civilian clothes arrived in two vehicles when the Ladakhi villagers were celebrating Dalai Lama’s birthday. They then showed them banners and waited there for 30-40 minutes but did not cross the Line of Actual Control,” the sources said. The Tibetans were celebrating the 84th birthday of the Dalai Lama.
