As a toxic chemical slick that originated in China’s Songhua River flows toward the border with Russia, officials of both countries are already working together to tackle the spill. The China Daily newspaper quoted sources from Heilongjiang province Environment Protection Bureau as saying that the slick was expected overnight Friday to enter the Heilong River (Amur River in Russia), the border between China and Russia. The spill, which occurred November 13, was caused by a blast at a chemical plant in Jilin City, Jilin province in northeast China. An estimated 100 tons of benzene and other chemicals polluted the nearby Songhua River, disrupting the lives of millions living near the water. The spill prompted joint action from the highest levels of government in China and Russia, though Chinese officials initially were mum about the incident before opening up discussions on dealing with the problem.
