The BRICS have been presenting themselves for several years as a credible alternative to hegemonic economic blocs such as the G7. In this context of increasing rivalries among powers, Russia has taken steps to expand this alliance. It then invited Saudi Arabia and Turkey to join its ranks. Moscow hoped to strengthen the bloc's influence on the international stage and to face the pressures from Western economies. However, these efforts encountered a rejection. This setback illustrates the divergent interests among these nations, as well as the challenges that the BRICS face in expanding their circle of influence in a world where geopolitical balances are becoming increasingly complex.
