Scuffles broke out on Sunday between police and 12,000 protesters calling for it to be moved. Riot police had to be delpoyed.
Xinhua news agency said officials ordered the plant's closure ''immediately'' and pledged to relocate it.
The BBC reports a storm last week broke a dyke around the plant, sparking fears the paraxylene it makes could spill. Nearby residents had to be evacuated on Monday. The dyke has since been repaired.
