Like I said in the past, India instigated a tactical plan to make moves in the south. It
did intrude into China (east Reqin) details of that are relatively sketchy but we know Chinese government officially declared this and even if Indian gov didn't (why would they) Indian military leaked videos showing something that confirms what CCP said and India media ran marathons with the story, probably with the support of the indian gov. It keeps its distance and doesnt need to admit it and it benefits from propaganda points. It just failed to convert that into anything worthwhile since China quickly expelled those Indians in east Reqin.
Then PLA held Black Top and Helmet Top (confirmation of this only happened in Sep and after iirc NOT actually August so even more for the point) and Chinese sources leaked that non-lethal DEW was used to quickly expel Indians. Chinese mouthpieces then said that Indian troops have vacated east reqin and the intrusion into China is resolved... CCP stopped complaining about it at this time. If CCP's intention was to "hide" this, it wouldn't have reported about it for two weeks.
India "captures" (

) its own peaks which PLA was not even remotely close to the entire time and makes it seem like they are preventing PLA invasion. Okay whatever it can indeed claim and say that since we can never know if that would have been a PLA intention but it remains doubtful since PLA wasn't even at Black and Helmet Tops until after August. If they wanted to invade into India, they would have done it.
