China enacted a new rule to ban smoking in enclosed public locations, according to the country's Ministry of Health on Tuesday.

The new rule, which will take effect on May 1, was added to the revised regulations on health management in public places from the ministry.

The new anti-smoking rule shows the government's resolution to intensify tobacco control efforts in China, which has ratified the Framework Convention on Tobacco Control of the World Health Organization, said Xie Yang, an official from the ministry.

The revised regulations also stipulates that business owners of public places should set up conspicuous non-smoking signs, carry out promotional activities to warn people of the danger of smoking, and dispatch personnel to dissuade smokers.

Further, the smoking area in outdoor locations should not occupy people's paths and cigarette vending machines should be excluded from public places, the regulation said.

China has more than 300 million smokers and a large percentage of the country's non-smokers inhale toxic second-hand smoke in public places such as restaurants, office buildings, schools, hospitals and public transport.

Figures show that tobacco use and second-hand smoke kill roughly 1.2 million people per year.

More figures:

A total 301 million Chinese, or 28 percent of the population, smoke cigarettes and 740 million people, including 182 million children, were exposed to second-hand smoke in 2010, according to the report "Tobacco Control and China's Future," released in January this year, by the Chinese Center of Disease Control and Prevention (CDC), according to Xinhua News Agency.

Smoking killed 1.2 million people in China in 2005, and the number of deaths was expected to reach more than three million in 2030, said the report, quoting the World Health Organization (WHO) and China CDC.
