Justin Rowlatt visits Brazil and the United States, two countries being turned on their heads by the new economic might of China, in the second film investigating the rapid spread of Chinese influence around the world. It's an epic journey, encompassing the pleasures of Rio, the glory of the Amazon rainforest and the United States of America - from California to the rust belt. Justin meets Chinese communities in unlikely places; witnesses the phenomenal impact of the Chinese hunger for resources; and encounters the rising undercurrent of American fury over their own decline in the face of competition from China.
