NEW DELHI: China has significantly ramped up its military presence in Pangong Tso, Galwan valley and several other friction points in eastern Ladakh even after reaching consensus with India to ease tension in the region, people familiar with the development said.

They said Chinese military has also deployed a sizeable number of its troops in Galwan Valley, the site of the violent clashes on June 15 that left 20 Indian soldiers dead.

The erection of a surveillance post by China in the area had triggered the clashes.

However, Chinese troops have again put up some structure around patrolling point 14 in the area, notwithstanding India's stiff opposition, they said.

Over the last few days, China has been laying claim over Galwan Valley though India called it "untenable".

Besides Pangong Tso and Galwan Valley, the two armies are also locked in a standoff in Demchok, Gogra Hot Spring and Daulat Beg Oldie in eastern Ladakh.

A sizeable number of Chinese Army personnel transgressed into the Indian side of the LAC.

China has also increased the number of troops and weaponry in several other key sectors along the Line of Actual Control in Arunachal Pradesh, Sikkim and Uttarakhand, the people cited above said.
