It's very unfortunate that lives were lost, whether they are Indian or Chinese. We will have to wait until more information come out to understand what exactly has happened. What's comforting, if there is any positive out there at all, is that the preliminary official statements from both sides seem to indicate neither side wants to escalate this militarily. The statements are more political and sticking to their respective positions, without making military threats. I take this as positive.
Let's refrain from extreme nationalistic rhetoric and taunting. It's just not helpful. It's not in India's or China's interest if a military conflict breaks out.
