A tough new smoking ban has been introduced in China's capital city Beijing. It coincides with World No Tobacco Day and was welcomed by the World Health Organization (WHO). The ban came into effect on June the 1st and is the toughest anti-smoking law to be implemented anywhere in China. It prohibits smoking in all indoor public places, on public transport and in workplaces. Unlike other bans in China, this one is backed up by hefty fines for anyone lighting up indoors in public. Restaurants will have a big part to play in implementing the ban. Restaurant owners will face a heavy fine if they do not stop people smoking. The public is also being encouraged to report anyone breaking the law
