Why is Brazilian President Lula so passionate when talking about elevating the voice of the Global South? "The geopolitics of 1945 don't exist any more," says Lula, "the world needs a stronger global governance." In this exclusive with CMG's Wang Guan, Lula explains why a new model of global governance, representing the political expectations of the entire human community, is needed for a better world. China has a role in that as well as the Global South. His pledge: "I will continue to work for it. I will continue to strengthen our relationship with China."
