As important as diplomatic engagements are, there are at least four reasons why these are a mistake in the present India-China context.
One, diplomacy has to be leveraged and purposed carefully in such manner that it is not converted to mere talkfests and demeaned in value. There have been a series of high-level civilian exchanges between India and China since the Galwan incident of June. The latest confabulation between the Indian and Chinese foreign ministers in Moscow on September 10, ‘lasted two and half hours’ but at the end of it, the Indian statement suggested that no progress was made. It pointed out that the ‘Chinese side has not provided a credible explanation’ for the deployment of PLA troops along the LAC and that their ‘provocative behaviour… at numerous incidents of friction along the LAC also showed disregard for bilateral agreements and protocols.’
In short, in this instance, diplomatic talks are unlikely to achieve what military commanders on the ground cannot.
