Mysterious are the ways in which multilateral groupings prosper and wither away. The Non-Aligned Movement (NAM) and G-77 had their heyday in the Cold War era. Later they lost their relevance, but they still exist. The South Asian Association for Regional Cooperation (SAARC) summits ended in 2014, but the Secretariat somehow keeps itself busy. Despite serious policy divergences on China and Myanmar, the Association of Southeast Asian Nations (ASEAN) continues to function, consuming reams of paper to issue long communiqués.
The case of BRICS is truly remarkable. Despite several achievements, it began to lose its sparkle. COVID-19, the Galwan clash, and the Ukraine conflict resulted in increased global economic stress, damaged India-China ties, and turned Russia into a diminishing power. The group may have lost its mojo, but numerous nations want to be admitted, thus showing the paradox of BRICS.
