The area is not accessible from the Chinese side whereas the Indian side has a road almost to the last point on which the Army can carry loads up to nine tonnes.
Chumar had become a flash point during the fortnight long stand-off last year in Daulat Beg Oldie (DBO) last year as the Chinese side had objected to overhead bunkers erected by the Indian side.
As part of an agreement reached at the flag meeting to end the stand-off from April-May 2013 at DBO, Indian side had to dismantle some overhead bunkers in Chumar.
Again, Chumar witnessed Chinese troops walking away with an Army surveillance camera on June 17 which was meant for keeping an eye on the PLA troops patrolling there. The same camera was returned after a few days.
