I'm not forgetting anything. You are bringing that up here to cement your previous position. Let me helpYou are forgetting that back in May China had an issue with India building bridges in the Galwan Valley and near the mouth. THe Chinese embassy specifically used the term Galwan estuary.
Your position was this - India has a problem with China having posts and armored divisions at the PP19.
You are trying to prove that China has issues with India too for border constructions India does. By that logic, both get even. Then you could argue that China failed in stopping Indian construction.
How nice. Won't be playing that game though.
