Prime Minister Narendra Modi has said that it is the first time the troika of G20 is with three members of the Global South - Indonesia, India and Brazil - and this can significantly advance the interests of the developing world. The troika refers to the grouping of three countries based on the previous, current and incoming G20 Presidencies. Where India is the current chair of the group of 20 leading economies, the country's predecessor was Indonesia and its successor will be Brazil.
