What if they ban like xiaomi or one plus. Those are like the most popular phones in India.
Is there some reason you think it would be?
Could you point to some specific cheap phones by those companies so I could see if I can find comparable phones by non-Chinese companies?

On Antutu benchmark, the Redmi is almost 5x higher [0]. So I don't think they can be considered "similar".
