"China will publish a list of its 10 worst - and best - cities for air pollution each month, a top leader said on Wednesday, as the country pushes officials to dispel a persistent smog crisis that is fuelling public anger. Vice Premier Zhang Gaoli said the move would help cities meet targets for cleaning up their air and promote more environmentally-friendly economic growth, the central government said on its website (www.gov.cn). It did not say when publication of the lists would start." (Quoted from article)
