Pollution 'to ease in five to 10 years'

Top climate change negotiator says China does its bit to cut emissions

China's air pollution problem will be alleviated in five to 10 years, the country's top climate change negotiator said on Tuesday.

Xie Zhenhua, vice-minister of the National Development and Reform Commission, was responding to recent fears voiced in South Korean media that pollution blown to that country from China has triggered cases of respiratory disease.
