Late last month, India says its soldiers thwarted the Chinese military's moves "to change the status quo" in violation of a consensus reached in past efforts to settle the standoff.
The activity last month and on Monday were alleged to have occurred on the southern bank of Pangong Lake, a glacial lake divided by the de facto frontier and where the India-China faceoff began in early May.
The standoff escalated to a medieval, nighttime clash on June 15 that was the deadliest conflict in 45 years between the nuclear-armed rivals. According to Indian officials, Chinese troops atop a ridge at the mouth of the narrow Galwan Valley threw stones, punched and pushed Indian soldiers down the ridge at around 4500m.
India said 20 of its soldiers were killed, including a colonel. China did not report any casualties.
The disputed and undemarcated 3500km border between India and China, referred to as the Line of Actual Control, stretches from the Ladakh region in the north to the Indian state of Sikkim. The nuclear-armed Asia giants fought a border war in 1962 that also spilled into Ladakh and ended in an uneasy truce. The two countries have been trying to settle their border dispute since the early 1990s, without success.
