I personally think China will eventually leave BRICS.
This could be an interesting opinion if you added some logic to it and try to explain why you think China would leave something they were one of the main founders of and is benefiting them greatly.
it wouldn’t be surprising if the countries in brics turned in on each other after they have defeated the us after all their intentions would be to improve their country’s standing
maybe china would push for their country and others wouldn’t like it and eventually leave or maybe they will all get along and have a global/international support group
