I have no problem with non Indian sources. No one is denying the Chinese have pushed ITBP patrols towards finger4.
If you are talking about that 60sq km area, remember we share roughly 3,500kms of difficult terrain with each other and the climate, geography so hostile that even with significant man power it is impossible to guard the entire LAC. That 60 sq km occupied at different regions is not a dazzling military acheivement as some Indian analysts and Pakistanis are assuming it to be. A little common sense would help.
Whatever floats your boat. I can't argue with ill informed stubborns.
