BEIJING, May 30: Chinese citizens alarmed about pollution won a rare victory on Wednesday when a city froze a chemical project after angry residents joined hands through a flood of mobile phone text messages.

Xiamen, a port city of about 1.5 million people in eastern China's Fujian province, announced it was halting construction of a plant to make paraxylene (PX), a petrochemical that goes into polyester and fabrics, the official Xinhua news agency reported.

Angry locals had denounced the project as an “atomic bomb” threatening the seaside environment, the report said, adding they had claimed to have circulated nearly a million mobile phone text messages urging family and friends to oppose the plant.

As recently as Tuesday, Chinese media quoted Xiamen officials as vowing the project would go forward despite the outcry.

The abrupt reversal reflected an increasingly potent combination of public worry about pollution, modern communications, and increasingly assertive citizens, said Zhong Xiaoyong, a freelance writer in Xiamen who opposed the plant.

“It's a step forward that shows they have to listen to peoples' worries about the environment, not just in Xiamen but across the country,” Zhong told journalists by phone.“Now nobody feels that they can avoid the effects on water, air, soil, and public awareness is growing that this is everybody's concern, not someone else's.”

China's leaders have promised to clean up skies and water, tainted by decades of largely unchecked growth, and environmental agencies are increasingly vocal about officials who push industrial projects without assessing the impact.

But local governments often remain eager to boost employment and revenues even if the environment suffers.

The plant is 7 kilometres from the city centre by the Taiwan-funded Xianglu Group and could produce 800,000 tonnes of paraxylene every year, the China Daily reported on Tuesday.Debate over the plant began to grow during the annual session of China's parliament, when 105 members of the Chinese People's Political Consultative Conference -- a usually sleepy talkshop -- raised doubts about the project, estimated to cost 10.8 billion yuan ($1.4 billion).

Public opposition began to build through the internet, which remains a lively forum despite government censorship.

“As soon as it enters production, all of Xiamen island and even the densely populated south Fujian peninsula will be caged under a toxic chemical industry cloud,” wrote one local blog author quoted by Phoenix weekly, a Beijing-based current affairs magazine.—Reuters
