Do you think PLA (or more accurately, CCP) is planning/expecting a fight in the long run? New airbase construction in tibbet, modernization of old ones, deploying greater numbers of assets. (specially J20 squadrons and Type-15 tanks)
From what I know of the CCP, a conflict of any real significant level with India is fraught with new level of risks long term that they adjudge as not worth exploring given India's size and role for this century and long term alliances it can strengthen counter to China's interests in deep ways. These risks were similarly not explored and pursued with the Soviets post ussuri clashes as again the risks were just too high at that point. The CCP is generally careful with larger countries with view of longer term....as China in general has bad experience with even smaller powers with simply sufficient force concentration and where buffers were not available (like in the western half of country) to delay and respond to them.
The larger Chinese population does not attach any significant value to the border with India as compared to say what Taiwan represents in Chinese redemption part of the psyche....and CCP is largely cognizant to that along with where Chinese population centres reside w.r.t its coastline and security risks stemming from far lower amount of buffer zone there and powerful allied threats projecting there relative to India (or say Russia today especially compared to what the USSR had in the coldwar calculus w.r.t PRC).
There is not much follow up pattern (its now past 3 years) after Galwan like say they did after the 1979 war with Vietnam for nearly 10 years. There are pressure points where PLA has optimal advantage right now to do so if CCP desires that and would likely have done so by now, but it has not and openly signals and prefers conservative approach.
So I believe its case of ramping up pressure and presence with prodding where possible within a larger status quo setting below large open or sustained conflict.
India of course as the weaker party has to plan with the worst case scenarios in mind as far as rationally possible rather than simply rely too much upon whats in the middle of the possibility curves like it has so far done since the 80s-90s thaw under Deng continued by the two successor administrations but now changing under Xi.
