Beijing is to impose smoking ban

For every three cigarettes lit worldwide, one is smoked in China. Almost 25% of the Chinese smoke.

Smoking is also contributing to a rapid rise of cancer and heart disease in the world's most populous country.

Enforcement team

In Beijing, the smokers are everywhere - and it feels like it.

But from Thursday, that may change.

The city authorities will impose a ban on smoking in most public buildings.

They say they are organising 100,000 existing employees to act as an enforcement team.

The authorities had wanted restaurants and bars to be mostly smoke-free as well, but there was too much resistance.

Instead, they must provide non-smoking areas or rooms.

Lack of awareness

"If measures are not taken, with so many smokers in China, in 10, 20, 30 years, the health system will have even higher burden to manage patients with cardio-vascular diseases, with cancer and so on," says Dr Hans Troedsson, the China representative for the World Health Organization.

"So it's a kind of sub-acute health threat here in China," he says.

The imminent Olympic Games have also strengthened motivation.

China wants to promote Beijing as a progressive, modern and clean city.

Less smoke and fewer cigarette butts could really help.
