Passage 2
Zhangjiagang is a commercial hub of Jiangsu,the fastest-growing province in China.China has the most dynamic economy in the world today.Iis boom radiates from Guangdong,its richest province,but it has spread as far west as Xinjiang,where foreign investors are searching for oil and other natural resources.It is creeping inland,from Jiangsu to the cities of Chongqing and Wuhan,where businessmen from Hong Kong and Taiwan are starting to spend billions of dollars to build factories.And it has penetrated the northeast ,where the city of Shenyang,long a moribund center of state industry,is bustling with new private business.Back in Beijing, officials at China's State Council,or cabinet,are giddy with excitement and exhaustion.“We don't have enough people. We don't have enough time,”says one.“Things are moving too fast.”
After a slowdown through 1990, China's economy bounced back mightily ,reaching a recent peak of 13 percent growth last year.Now,some Western experts are predicting that China could become the world's dominant economy early in the 21st century.
