Nearly 200 government departments, government-affiliated institutions and State-owned companies in Beijing have started a campaign to eliminate smoking in their buildings.

"The organizations taking part in the campaign have shown great enthusiasm," said Zhao Chunhui, deputy director of the Beijing Municipal Health Bureau. "We planned to have 100 such organizations take part in this campaign, but ended up with 170 by the end of April."

The 170 organizations include ministries of the central government, such as the Ministry of Industry and Information Technology, the ministry leading the tobacco control efforts in China.
