Cities struggling to enforce bans on smoking in public

As China eyes a national ban on smoking in public indoor areas, health and law experts say regional anti-smoking regulations lack the teeth to protect nonsmokers from secondhand smoke.

More than 10 Chinese cities currently have smoking control rules, all of which ban smoking in public indoor areas, said Wang Qingbin, associate professor with the China University of Political Science and Law.

"But implementation of the law is unsatisfactory, mostly because there is a lack of enforcement and awareness of the law," he said at a symposium held by Beijing-based tobacco control campaign ThinkTank and the Tobacco Control Office of the Chinese Center for Disease Control and Prevention.
