In the mid 80's, China moved from exporting raw materials to exporting finished products. In the 90's, from light and textile industries to electrotechnical products. In the 2000's, share of high-tech products increased, most important being electronic and informational technologies. In 2005, almost half of exports of China was machinery and electrotechnical products (including appliances), with textile and metallurgical products ranking second and third (14.3% and 8.8%).

China is a bubble, they have been generous with their excesses.  expansion is their only option, maintanence alone will not keep their economy healthy.
