Para-xylene is a common chemical used to manufacture polyester. The chemical seems to have a low toxicity and there are very few reports worldwide of environmental harm from PX. Despite this, "PX has become a common target for public protest in China since December 2007 when the government of Xiamen suspended the construction of an £882 million PX factory. Since then, PX projects have been halted in Dalian, Ningbo and Kunming as a result of public discontent". A paraxylene (PX) plant in Jiujiang was proposed by the Jiujiang Petrochemical Corporation and got the first EIA published on 4 April, 2012. It was approved peacefully, due to the harmonious coexistence between local residents and the company. This was unusual though, as in other sites where PX plants have come up, citizens have vehemently protested. In fact, the State Environmental Protection Department believed that PX plant was a sensitive activity. As a precaution, national Ministry of Environmental Protection required Jiujiang Petrochemical Corporation to provide more public information. So, the company published an article in “Xunyang Evening News". Short after, on May 4th, under the impact of the controversy over planned paraxylene (PX) plant expansion in Kunming, a group of citizens started to consult the PX plant in Jiujiang. On May 6th, the Jiujiang News Forum appeared the first anti-PX article, titled "PX plant planned to settle in Jiujiang. The people of Jiujiang come to die", which wrote: "PX plants in Xiamen, Dalian, Ningbo and Kunming stopped, why has Jiujiang continued? Who wants it?" It has elicited a great deal of public attention and concern. On the 10th, articles about Jiujiang PX plant posted on Jiujiang News Forum get more than 23,000 hits and replies of 358 people. Residents announced a sit-in at municipal government building to protest against construction of paraxylene (PX) plant in Jiujiang on May 13th. At this critical moment, Jiujiang Petrochemical applied to the local government for emergency help. Jiujiang municipal Party committee and municipal government launched the emergency status for maintaining stability, which comprised of measures by police, propaganda department, environmental protection department, security department, etc.
