As I said, the 20% is the area between the Chinese and Indian lacs. This vast difference in perception is why there are frequent standoffs.
Don't know how you can say India controls 0% of the dispute when by now it is clear India has many positions within the 20% between the Chinese and aindian perception, including in areas that were previously unoccupied by both sides.
Didn't I keep saying India and China BOTH have positions within the 20%?
Do you need reminding that China didn't have positions inside the 20% and now does?
Previously 20% was unoccupied by both sides but patrolled very frequently by India. Now both sides have mirrored positions within 20% with buffers. Buffers that China got out of India only in exchange for China's forward positions.
