The New Development Bank, or NDB, was established by five BRICS countries in 2015 to fund global development cooperation. During the 8 years since its founding, the bank has approved a total of 98 projects on infrastructure and sustainable development all over the world.

What impact has the bank had on global development cooperation? And why does Dilma Rousseff believe in the future of the bank despite skepticisms in the West about BRICS and related institutions?
