On the topic of Chinese economy, this one is an interesting read:

The gist of it is, Chinese growth is (has been) hugely dependent on construction on a massive, unsustainable scale. For example, in 2010 China consumed 55% of the world's cement and 60% of new elevators delivered while the Chinese economy is only around 8% of the world. The same year, they built enough urban residential housing to accommodate 60 million people, while the urban population only increased by 20 million. The rate they are going, pretty soon you will have a nation of construction workers with nothing meaningful left to build.
