The 16th BRICS Summit is scheduled to kick off in Kazan, Russia. It will be the first summit of all BRICS nations since it expanded from five to 10 members and the entire world is watching how these nations will reach consensus in the newly-expanded bloc. In an exclusive interview with CGTN, Columbia University Professor Jeffrey Sachs noted that BRICS is not only committed to deepening internal relations, but also to building strong ties with emerging economies and developing countries, leading the way to the formation of a truly multipolar and multilateral world.
