Not confirmation, that's continued salami slicing sheninagans i.e. cartographic normalization and stapled visas instead of stamped visas to delegitmize AP citizenship. PRC will always rhetorically state AP is south Tibet because that's just how geopolitics works, you don't preemptively concede you don't claim something you claim even if said claim is to get something else because that weakens claim. PRC will always publically hold position all of AP is Tibet, i.e. maximalist bargaining position, until package swap is accepted first behind close doors because anything else weakens claim.
Package swap deals is not something offered in low level talks, it's leader to leader offer, i.e. Zhou Enlai to Nehru, Deng Xiaoping to Ghandi. Modi's been dipping meeting Xi (or vice versa if you want) until last year, right before trump2 and it's been rollercoaster geopolitics. Until India, PRC, US triangulation / dynamic becomes cleares and Xi/Modi relations normalize the only thing boundry talks do is what it always does, maintainence work with some progress towards normalize relations where high level boundary talks can start, as in actual formal settlement, not LAC management homework, i.e. we're past generals talking in tents to ministers meeting in capital, and maybe one day leaders discussing swap.
In the meantime, in addition to talks, the new normal PRC wants to set is to continue adding pressure via salami slice and rachet pressure because PRC isn't interested in settling for status quo (talks) where nothing happens, i.e. India wanting pre 2020 status quota ante, basically PRC perceives to be (decades of) deliberate stalling, so PRC will continue to add pressure so situation doesn't settle into unproductive status quo ante dynamic again. Bluntly it is better for PRC if PRC/India draws blood every once in a while to keep the pressure up because that might lead to earlier settlement than the alternative, drawing patrol routes and words which hasn't lead anywhere. Anything that can move the settlment clock forward.
E: alright really last reply, you can believe what you want. But ultimately, ask yourself, do you think PRC can invade and hold Arunachal Pradesh, through Assam Himalayas. Exceedingly unlikely, geographically logistics harder to sustain than TW. It's more trouble than it's worth.
