The gap between rich and poor will increase. The inflation will make that prices of basic commodities become unavailable for a great majority of Chinese.

Chinese parents will still have to rely on their own parents to take care of their children, so that they can keep enjoying their night life or go out with colleagues or friends.

Chinese businesses will keep copying anything invented in Western countries.

Tainted powder milk, pork, vegetables and fruits will still create new scandals until a high government official or two get their child sick and wants a revenge.

Taiwan will still be on its own, providing that the Chinese troops don't invade the island.

Chinese will keep doing poor building and construction as good and quality material become less and less available.

Capitalism and materialism will become the credo of the new China : Get rich is not enough, get richer is better. Keep what you own and don't let anybody take it.

As for the people, Chinese will remain Chinese as they are now (with some good qualities, but also the bad qualities).

In the overall, you see now the China of the future, with more people, less quiet, more pollution and more waste.

I'd say a growing population, sinking resources, growing gap between rich and poor will cause the major cities to wall themselves off from the rest of the country, especially when the market from cheap consumer goods moves to another country. Massive construction will continue to occur inside the walls to show how powerful the cities are, as cheaply constructed slums form outside the city wall. Smog and pollution will increase and the sky blackens.

I see a possible post-apocalyptic look but with over crowed slums outside of the city gates instead of empty deserts.

in 20 years they will be the biggest economy of the world and they will shape the world
maybe in 50 years, after china got the first economy rank in the world, asian countries will choose communism (especially the former ussr countries)
