Another sovereign nation seeks membership.

The Islamic Republic of Iran has officially submitted its application to join the group of five leading economies made up of Brazil, Russia, India, China, and South Africa, the foreign ministry in Tehran announced on Monday. The move comes after the Iranian president addressed the BRICS summit last week.

While BRICS is not a treaty bloc, it has a “very creative mechanism with broad aspects,” Iranian Foreign Ministry spokesman Saeed Khatibzadeh said on Monday, according to the Tasnim news agency. He added that Tehran has already had “a series of consultations” with BRICS about the application.

The goose is beginning to cook.
