The original " China secured 19XX line " was from an Indian politician / personality itself. I'm doubtful as to what exactly are China's claims since 1962. Seems like China has shelved looking to settle on any fixed claim since
1. This means less maneuvering space in that region in the future regarding anything related to Pakistan and its node of BRI ( CPEC).
2. Attention falling to South Tibet part where India can really open a good front .
(note: few pages back I remarked that China had settled border disputes with many SE nations and included Combodia. But Combodia doesn't share a border with China. It is Laos which settled the border disputes.)
Yep, which is why I keep saying that this whole fantasy-map line of argumentation that Indians have been pushing is besides the point. It's a diversionary tactic. What matters is the military posture, strategy/goals and capabilities in theater, and yet this thread has been focused on the fantasy maps, because people keep taking the bait and falling into troll-traps.
