Go back a decade or so. China would never comment or come out against India in any international fora although silently it did treat India as a competitor locally if not globally.
India consequently, has also been very lackadaisical when it came to making certain decisions just because they didn't want to antagonize their northern neighbors. There was a clear lack of understanding of the extent china opposes India.
Now that china has played it's card, it would help the domestic discourse to move forward in India and make firm independent decisions keeping in mind that China is it's sole adversary.
Such open hostility is a first. Indians should be happy that they have a very strong leadership which forced China to open their cards. If you guys have played competitive poker, you will consider it a victory at some level.
