We begin in Johannesburg, where the leaders of the five BRICS nations - Brazil, Russia, India, China and South Africa - have attended the 10th BRICS summit. They exchanged in-depth views on BRICS cooperation and major international issues of common concern, reaching broad consensuses. CGTN's Vauldi Carelse has more.

They lead the world's top emerging economies. And their activities here in Johannesburg are being watched worldwide. The shadow of a global trade war has been hanging over this summit. China's President Xi Jinping already has warned, there can be no winners. That's not the only issue the BRICS leader are grappling with. They also are seeking a response to the rapid advance of technology - the so-called fourth industrial revolution.

CYRIL RAMAPHOSA SOUTH AFRICAN PRESIDENT "We proceed from the understanding that this is not simply a digital revolution, but a fundamental shift in the way people live, work and relate to each other. It has the potential to solve many of the social problems we face, by better equipping us to combat disease, hunger and environmental degradation. However, unless it is approached in a collaborative manner, underpinned by a developmental agenda, rapid technological change could merely serve to entrench existing disparities within and between countries."

President Xi told his peers, they need to co-operate more and to get closer.

XI JINPING CHINESE PRESIDENT "At the same time we must work together at the United Nations, the G20 and the World Trade Organizations to safeguard the rule-based multilateral trading regime, promote trade and investment liberalisation and facilitation and reject protectionism outright."

And Russia's concerns - that BRICS members collaborate to combat extremists and cross-border crime.

VLADIMIR PUTIN RUSSIAN PRESIDENT "BRICS membership is reacting jointly to the threats and challenges we face. We are cooperating in fighting terrorism, extremism, drug trafficking, trans-border organized crime and BRICS has unique play in the global economy."

The BRICS leaders have agreed to sign up to a so-called Johannesburg declaration - More than 100 separate resolutions - from co-operation on peace and security to global economic recovery, to women's rights.
