I’ve listened to last audio of the solari report and I think there was a misconception about the role of the BIS in the new BRICS financial system. The mbridge system is not controlled by the BIS but the latter is a member otherwise the system wont take off. A better source to understand what the gameplan is would be the whitepaper of the “Unit” cryptocurrency.
The project is a Russian Idea built and implemented in Hong Kong by the Chinese. The plan is to give every country as much flexibilty as possible in implementing things like capital controls or industrial policy.
