I think China now has a well developed standard for building up tensions between other countries like the others have said, it could be a negotiation tactic or something if India are showing similar tensions. I also don't think Indias army is anywhere close to the strength of China (but I might be wrong on this as I haven't studied the two). There may already be tensions due to china's cover-up of the virus and a lot of people seem to think they weren't badly affected by it which could be a stance a lot of governments take (even though a lot of sources have proven China took quite a hit to its economy and population).
