China is certainly emerging as a Superpower but remember its government still manages the economy, not the best alternative. More importantly the have and have- not divide is significant. Yes, there is a thriving 300 million middle class segment but what about the other 1 billion? Corruption and looming environmental problems may limit how far China can advance along with population issues caused by Mao's one child policy which resulted in a decline in the female to male ratio. India doesn't have the latter issue but shares some of the former issues. It took two World wars, a few local wars, and some pretty stupid pollies to reduce the UK to its present status, a process that took 100 years. The USA will be a major force for sometime to come.
