Violence between India and China has erupted in and around the Pangong Tso Lake in recent months.'
Kicking and punching, stone hurling, and the use of sticks and steel rods have all been described as causing serious injuries.
Normally, the two patrols would have practiced a "flag exercise," in which one side would show a banner asking the other to leave its territory.
This exercise could last anything from a few minutes to an hour.
Except for a little jostling here and there, the two sides would separate gently.
Due to heightened tensions between the two troops at Doklam on the Sikkim border, the Chinese chose to launch violence against the Indians this time.
What is Pangong Tso's significance:
Pangong Tso is a long, thin, deep, landlocked lake in Ladakh, Himalayas, at a height of almost 14,000 feet.
The 135-kilometer-long lake, which is shaped like a boomerang and spans 604 square kilometers, is 6 kilometers wide at its widest point.
Pangong Tso's western terminus is 54 kilometers southeast of Leh.
In the winter, the brackish water lake freezes over, making it perfect for ice skating and polo.
What is the source of the conflict:
The Line of Actual Control (LAC) runs through the lake, but its exact location is disputed by India and China.
When the Army unit from the region was relocated to Kargil for Operation Vijay in 1999, China took advantage of the chance to construct a 5-kilometer road along the lake's edge inside Indian territory.
Chinese fortifications on the northern tip of Pangong Lake physically overlook Indian positions from one of these roads.
Currently, India controls a 45-kilometer stretch of the lake's western shore, while China controls the rest.
The majority of the battles between the two armies take place in the lake's disputed area.
What are the territorial rights in this area:
The Chinese had a significant advantage over the Indians, as their superior boats could essentially run circles around them.
India, on the other hand, purchased superior vessels, prompting a speedier and more aggressive response.
Tourists were not permitted to visit Pangong Tso until 1999, and even now, an Inner Line Permit must be obtained from the office of the Deputy Commissioner in Leh.
Tourists are now only permitted to travel up to Spangmik village, around 7 kilometers into the lake.
