The move is not so easy. Chinese has the work ethic (combination of high IQ, disciplines, hard work spirit, can do spirit and sense of responsibility) which is equal, if not superior, than German (i m talking about pure German, not current melting pot Germany, which the work ethic going down the drain and German quality no longer being envied. Have worked with too many German equipment and really dissapointed) but the salary is much lower. The consequence is the effectiveness of the whole process, from raw material, manufacturing to logistics and trade. This cannot, and never will, be repeated in any country or continent at similar scale. If China was to be isolated as before 1980, the whole world manufacturing would collapse before it can be rebuilt.
My mother came back after getting a Ph.D in East Europe in early 1980s. Even back then, Chinese goods already conquered the market and most items she brought back home were made in China. At that time, Vietnam and China had no formal trade.
