US have ruled the world since the WWI and WWII. It´s the biggest economy in the world, one of the most developed and had done a remarkable job on "protecting the advantages of the free world." China, otherwise, has a marvelous history of development, from the most impoverished country of the world in 1950 to the second economy in 2015. Better policies, efficiency, courage, strongness and so far more to prove its value. In your opinion, will China drive the world better than the US?
