China to create largest mega city in the world with 42 million people ... China is planning to create the world's biggest mega city by merging nine cities to create a metropolis twice the size of Wales with a population of 42 million. City planners in south China have laid out an ambitious plan to merge together the nine cities that lie around the Pearl River Delta. The "Turn The Pearl River Delta Into One" scheme will create a 16,000 sq mile urban area that is 26 times larger geographically than Greater London, or twice the size of Wales. – UK Telegraph
