You are not making any sense. The Galwan mouth is where the galwan meets the shyok. Between that, I have already shown images of Indian permanent camps and infrastructure in the valley. So no, China did not acheive its objectives therePretty much every single chinese media, even your own satellite images, put china's LAC in the pp14. How do you get the idea that china wants to invade all the way into the river mouth? This statement is false simply because it's you who started the incident, as written in the link that you yourself put?
If china does want to invade and change the LAC, why is india the one who take the initiative and intrude to pp14, as shown with the written statement and the satellite images?
All China asked in the statement is to empty the area between the mouth and pp14, which as you again posted here, have been done by your side. How's that a lose for china, manage to ask you to empty part of your own area? You see a pattern here? Buffer zones includes indians emptying f3-f4, galwan valley includes you emptying mouth to patch of land near pp14. Classic india, 'winning' by vacating it's own territory at china's behest lmao.
And by your logic, india vacated f4-f5. China vacated f4-f8 and agreed not to patrol beyond finger 3. Yes, big win for China by retreating from its own claimed territory.
