About 200 people staged a rare protest in a city in southwest China against construction of a major petrochemical complex, saying it would lead to serious air and water pollution, local media reported on Monday.
Protesters in Chengdu, capital of Sichuan province, marched peacefully for about two hours on Sunday to demonstrate against plans for an ethylene plant and an oil refinery on the city’s northern outskirts, the Beijing News said.
“Because of fears that these two projects, when finished, could seriously pollute Chengdu’s air and water resources, the people ‘took a stroll’ to express their opposition,” the paper quoted an unnamed resident as saying.
