No one is preaching about that being an exclusive Chinese win.India was perfectly fine with pangong 4-8 being a buffer zone. Read what colonel Dinny wrote about that. It was China that tried to forcefully occupy that by building infrastructure that is permanent in nature to try and gain an advantage over India in the region, but was forced to withdraw. Even if that is not a complete Indian victory, I fail to see how that is a Chinese win.
The buffer zone is between F2/3 to F8 with a good infra in place from F8 to F4.
