Answer:
Developing countries
Explanation:
Developing countries such as China, India, Brazil and Indonesia are expected to grow faster and significantly more than developed economies. In part, the reason for this is that developing nations tend to grow more than developed nations in general, because advanced countries have reached a level of economic development from which it is hard to go on.
China specifically is expected to overtake the United States as the number one economy in the world in the following two decades.
