China's capital, which is to host the Olympics next year, will also increase rewards for uncovering unlawful production methods from 10,000 yuan ($1,300) to 50,000 yuan, the Beijing News reported.

Beijing "this year will set up a supervision system to analyse food additives, and intensify management of the approval system and record-keeping of food additive enterprises," the report said, citing a proposal initiated by Beijing city official Wang Weicheng.

Beijing is also extremely sensitive to ensuring every aspect of security -- including food safety -- for the 2008 Olympic Games, when millions of athletes, tourists and journalists will descend on the city.

The strengthened oversight will focus on food additives, the report said.

Beijing will set up a system to trace back food and food products to their origins and will strictly monitor the use of fertiliser and pesticides.

"Goods from companies that don't meet production standards will be firmly kept out of the market," the report said.
