BRICS began with Brazil, Russia, India and China (BRIC). NEW DELHI: Delhi has been turned into a fortress.

Roads are being secured, security has been stepped up and the capital is preparing for the arrival of some of the world’s most powerful leaders. Russian President Vladimir Putin, Chinese President Xi Jinping and other leaders are set to gather for the Brics Summit, turning New Delhi into the stage for a meeting of a bloc that now represents nearly half of the world’s population.

But beyond the motorcades, bilateral meetings and summit optics lies a much bigger test. 5% of the world’s population, Brics is no longer simply a grouping of emerging economies.

As India hosts the 18th Brics Summit on September 12-13, New Delhi now has to show what it can do with that growing weight. India has spent its 2026 chairship pushing the grouping towards more practical cooperation: from food and energy security to critical supply chains, artificial intelligence and development finance.

The challenge now is whether those efforts can translate into meaningful outcomes at a time when wars, tariff battles, supply-chain disruptions and geopolitical rivalries are reshaping the global economy. A bigger Brics, a bigger global footprintBrics began with Brazil, Russia, India and China, with South Africa joining in 2011.

The grouping expanded significantly in 2024 with the addition of Egypt, Ethiopia, Iran, the United Arab Emirates and Saudi Arabia. Indonesia joined in 2025, taking the number of full members to 11.

The bloc also has 10 partner countries: Belarus, Bolivia, Cuba, Kazakhstan, Malaysia, Nigeria, Thailand, Uganda, Uzbekistan and Vietnam. The expansion has dramatically widened Brics’ geographical reach across Asia, Africa, the Middle East and Latin America.

It brings together major energy producers, manufacturing powers, large consumer markets, commodity exporters and rapidly developing economies. Diversity is both an asset and a challenge.

Brics has emerged as an important platform for major emerging economies to coordinate positions on global governance, development, trade, finance and technology. Yet the same diversity makes consensus more difficult.

Unlike a formal economic union, Brics has neither a single economic policy nor a common foreign policy. Its members have different political systems, economic structures and strategic interests, and in some cases, sharply divergent positions on major international issues.
