"From the commercial bustle of Shanghai to the renowned natural beauty of this city, President Clinton devoted two of the closing days of his China tour to a campaign aimed at persuading the Chinese that robust economic growth does not have to come at the expense of their country's fragile environment.</br></br>Clinton spent Wednesday touting China's recent moves toward market economics, including a tour of the Shanghai stock market and a luncheon with young entrepreneurs. But his generally ebullient remarks were tempered by a dire warning about the damaging effects that China's industrialization is having on air, water, and food quality.</br></br>Clinton continued to develop his environmental theme here in Guilin, where the Li River and the unusual limestone formations that jut up out of the valley floor create a striking natural tableau that has been memorialized for centuries in Chinese art.</br></br>Cooling himself in sweltering heat with a colorful Chinese fan -- he called it ""an energy-efficient air conditioner"" -- Clinton told Guilin residents today: ""China has a unique opportunity, because you are developing rapidly but later in time than other countries, to avoid making the same mistakes we have made.""</br></br>In the speech, Clinton announced a number of initiatives that will provide U.S. assistance to an incipient Chinese anti-pollution movement."
