Being a developing country used to be easy. You followed leaders - Japan, Hong Kong, Taiwan, South Korea - up a well-trodden ladder from agriculture through manufacturing to services. Starting with tilling the soil, you moved on to turning out T-shirts, then toys, then tractors, then television sets, and ended up trading Treasuries.

The rise of China has made that less straightforward. Not only is the first rung harder to reach, thanks to the hundreds of millions of rural migrants to Chinese cities still willing to work for low wages stitching garments, but also exports of goods from China's coastal industrial fringe are rapidly becoming more sophisticated, threatening those halfway or more up the ladder. While the shoemakers of Italy and the steelmakers of Pennsylvania may complain loudly about Chinese competition, those with more to worry about are middle-income Asian countries geographically and econ-omically close to the Middle Kingdom.
