After the standoff began early last month, the Indian military leadership decided that Indian troops will adopt a firm approach dealing with the aggressive posturing by the Chinese troops in all disputed areas of Pangong Tso, Galwan Valley, Demchok and Daulat Beg Oldie.
The Chinese Army is learnt to have deployed around 2,500 troops in Pangong Tso and Galwan Valley besides gradually enhancing temporary infrastructure and weaponry.
India has also been bolstering its presence by sending additional troops and artillery guns, the sources said.
The trigger for the face-off was China's stiff opposition to India laying a key road in the Finger area around the Pangong Tso Lake besides construction of another road connecting the Darbuk-Shayok-Daulat Beg Oldie road in Galwan Valley.
