To avoid escalation, both sides should agree on the “Line of Actual Control”
Yet whatever the efficacy of generals meeting in windblown tents, it is a reckless way to fix problems between two rising nuclear powers that are home to a third of humanity. India has previously suggested that, as a second-best to a formal agreement over where the border lies, the two sides should at least present maps showing their view of where the line of control runs in practice. China, perhaps thinking itself the more astute Go player, has always refused to do so. This allows it to claim that any Indian move is a violation of its own understanding.
