It’s a little more than posturing, India and China have been at odds for a while. They’re frequent competitors for resources on the open market, which China has a better position in. China has also antagonized India over their borders in the Himalayas in Kashmir, as well as encroached on Nepal’s borders (which India views as a necessary buffer state and an in-kind extension of Indian territory).

Modi’s for sure been causing a lot of anti-democratic ruckus domestically, but his anti-China stance is pretty valid.
