Protests in the eastern Chinese city of Qidong ended with victory for opponents of a government-run pipeline project that they claimed would increase pollution in local waters . But it also appears to have exacerbated anti-Japanese sentiment both locally and on the Chinese Internet. Officials who oversee Qidong, a coastal city that faces Shanghai across the Yangtze River in China’s Jiangsu province, said Saturday they would “permanently halt” a pipeline construction project intended to pipe water away from a paper mill owned by Japan’s Oji Paper Co. Local officials will now consider other ways to clean or transport the water that will come from the mill, which Oji Paper said is worth $1.95 billion.
