I don't understand, are they camped Indian side of ladakh or in Chinese territory? someone please answer
Because India-Tibet border has never been delineated in history.
India and china were never "neighbouring countries" in all history. But that changed when china occupied Tibet.
Till Tibet is resolved it will quite impossible to resolve the Ladakh-Tibet border (even though, Aksai chin is well within Ladakh.. and current LAC is basically intrusion of PLA into Ladakh in 1959).
The LAC is not demarkated .. it exists but very roughly.. on basis of physical troop presence.
Setting up a new "tent-position" is clearly a violation of agreements between India and china. Very likely it will be peacefully removed without a bullet being fired.
