Hate to disappoint you but "mutual disengagement" was what you yourself were repeating so often few months back.I hate to dissapoint you, but no notable international media outlets have media outlets have published tgose images. And despite your trolling, it is a fact that China retreated fron the la c in multiple locations. Those "irrelevant satellite images" show that quite clearly.
And in many locations, if you consider China as the advancer (encroacher) it'd mean the buffer zones are majorly in what was previously thought to be Indian controlled regions.
The multiple satellite images, if at all they show anything substantial in the rare cases, also show that clearly.
