Beijing will take tough steps to control air pollution during the APEC senior officials' meeting in the city by launching stricter emergency actions than called for if a pollution warning is issued.

China is hosting the Third Senior Officials' Meeting and related meetings of the Asia-Pacific Economic Cooperation in Beijing from Aug 6 to 21, when there will be about 100 sessions covering topics including trade, investment, agriculture, food and anti-corruption.

The senior officials' meeting will involve a large number of participants and a more intensive schedule than the two previous meetings, which were held in Ningbo of Zhejiang province and Qingdao of Shandong province.
