Question: Does China have greenbelt policies for its biggest metropolitan areas, like London or Portland? This is because if cities like Beijing and Shanghai have population caps in the central city, won't this just encourage more and more urban sprawl (i.e. Shanghai and Suzhou linking up to become essentially one big continuous urban area like Tokyo and Yokohama, if it hasn't already)?
Watch this vid, Yukon explains how China can build lots of 50 million pop metros like Tokyo and it's for the better due to higher efficiency.
@Crang Only ones preventing North Korea from developing are the American bases in Korea and Japan. North Koreans are just as capable as Chinese/South Koreans, perhaps even more so due to their discipline and lack of Western brainwashing.
