BEIJING: Residents of a Chinese city plagued by pollution are mobilizing against a proposed chemical plant that they say could harm their health, with some urging marches against the plan, which they say puts growth before the environment. The plant proposed for Taizhou, Zhejiang Province, on the eastern coast of China, would make paraxylene, a petrochemical also known as PX and used to make polyester. Last year, protests against a PX plant planned for another coastal city, Xiamen, led to its being shelved. Now Taizhou residents, dismayed at the prospect of another chemical plant /in an area already crowded with them, are threatening to re-enact those protests. "Resolutely oppose the PX project. As Taizhou residents, everyone must take some action," said one message on a local Web site (bbs.taizhou.com) that has served as a platform for those opposed to the plant. "We want clear water and green hills, not toxic cash." Leaders in China have vowed to create what it calls a more "harmonious society" with cleaner air and water, even at the cost of slower economic growth. But this dispute threatens to become another battle pitting citizens with environmental or health concerns against local officials whose priority often remains attracting fresh investment and revenue.
