I guess the definition of "international" here is NATO.
BRICS have a population of 3.24 Billion. B - Billion.
NATO has a population of about 950 Million. M - Million.
BRICS countries are actively Trading with Russia.
America's favorite ally in the Middle East, Saudi Arabia is doing deals with Russia and Iran. BTW Saudi Arabia wants to join BRICS.
Iran is friendly with Russia.
>India and China despise each other and are becoming more, not less hostile. China has pretty openly racist views about India and doesn't treat them like equals in any way shape or form.
You are not completely wrong about this. Still India and China Trade is USD 135 Billion. That's after many restrictions they impose on each other.
In the Indian and Chinese mindset, it's a very practical relationship. Don't consider each other friends, do business when necessary.
About your last point. Chinese don't consider anyone as their equals.

The world order is changing. BRICS countries are not dictating to anyone how they should live. They are just finding new opportunities among themselves.
