The Chinese have clearly come to the Galwan Valley with a large force and have dug in to fight it out. Perhaps around 5,000-6,000 or more (even 10,000). They are there with the express intention of staying put to reinforce their claim to this area, as is further evidenced by the very recent proclamation by China's foreign ministry spokesperson, that Galwan Valley is located on “their side” of the LAC.
The façade of dialogue starting at the Corps Commander level, followed by Major General level and then at the Brigade Commander /Commanding Officer level, was obviously initiated to gain time to build up logistically and deploy artillery and other firepower on their end.
