At various times since 1850 different countries have been the worlds main exporter of goods - the UK 1850 -1890, Germany 1890-1910, USA 1910 -2010, China 2010 - none of them finished up "enslaving" the whole world
I'd put my money on India to replace China eventually and then Brazil & Nigeria beyond that
