From the looks of things, other nations in BRICS and SCO simply ignore India and do what they need to get done - usually with China. eg Pakistan's BRI projects.
India even refuses to open its market for RCEP, and looks like it won't open its market to anyone who isn't a white anglo and even then, not every anglo american company can make money from India without having it stolen and then being forced to leave the country, rinse and repeat.
Agree on the ignoring India. Just do not allow India to play the spoiler in these organization. India can leave whenever it wants.
i'm not sure why the surprise that India doesn't want a BRICS currency. Such a currency always seemed to make no real sense to me.
If China wants to offer alternatives to USD, it needs to work harder at internationalize RMB. It has plenty of assets it can use to back it. Just needs to figure out the best way to do it.
India will do things that are in India's interests and that means wobbling between different blocs
Again just ignore India. No need to let them act as spoiler.
