As a partner-state rather than a full member-state, however:
Cuba and Bolivia are expected to officially join BRICS as partner states on January 1, Russian Deputy Foreign Minister Sergei Ryabkov has said. In an interview with the Izvestia newspaper on Friday, Ryabkov confirmed that both countries had received invitations.
“We are confident that everything will work out in terms of their joining the group as partners,” the diplomat said.
The new ‘partner country’ status was approved at the BRICS summit in October, hosted by Russia in Kazan, and is intended to serve as an alternative to membership after more than 30 nations applied to join the organization.
I think the more noteworthy item is the absence of an invitation for Türkiye. One would have thought they would be a shoe-in, but perhaps the Turkish invasion of Syria was more than the BRICS members were willing to accept. I also find it curious that neither Malaysia nor Vietnam were accepted, but it might be that there will be a separate announcement concerning the new Asian member-states coming from China.
