Have not heard about this only Nepal border and Bhutan border issues. I don't think anything is going to happen between India and China because at least for China, it 100% will want to avoid war. Only possible war is between China and USA soon. These stories are quite strange. One week some big fights and another week some soldiers captured but nothing in other media. Anyway if big changes happen in border, we will hear about it everywhere across the world and only then maybe there will see some action. But these attentions are quite fake like recent broadcast from Pakistani president about Indian imminent invasion. Everything between Pakistan and India is about Kashmir right now at the forefront.
PLA generals in two years old debriefing video explained India and China dispute in Doklam past years and explained how war very close could have happened but CCP and Indian leaders decided no to war. I think at that level both sides have much grander plans and attention elsewhere not just talking about who win or what. It's safe to say both sides have a certain kind of understanding which means definitely no war. However Pakistan and India is another issue and China will of course stand with Pakistan side due to politics. For China's considerations on why to avoid war is because it is too distracting from China's real problems. However Indian narrative is growing stronger and stronger against CCP about same level as CIA or whatever western plans for sabotage. So perhaps the issue becomes more severe between India and China in future but now everything can turn in any direction still. War is expensive and will be too unpredictable. Before when British conducted Opium war and eight nation war on China, Russia immediately seized many parts of north eastern China. Something similar can happen with USA and SCS bases if PLA gets too distracted. All these talk about fighting etc never come from Chinese side when the topic is India border. I think most Chinese don't even know much about the history except until last few years.
