From Reuters:

China has further tightened smoking restrictions — targeting schools and day care centres — as it extends a crackdown linked to its pledge to hold a smoke-free Olympics.

Last month, Beijing formally pledged to restrict smoking in most public venues in the city, including government offices and public transport, beginning on May 1.

In a separate move reported on Wednesday, China ordered primary schools, secondary schools and day care centres across the country to prohibit even designated smoking zones, an effort to promote ‘non-smoking campuses’ ahead of the Games.
