The PLA is also testing Indian deployments at a few places along the 1,597-km frontier in eastern Ladakh, stretching north to south from Daulat Beg Oldie (DBO)-Depsang, Galwan, Hot Springs, Pangong Tso, Chushul, Demchok and Chumar sectors. On Tuesday, for instance, several PLA vehicles came close to the LAC in the Chumar sector but there was no attempt to intrude, said an officer.
