BEIJING -- China will continue to improve the traceability system of baby formula to cover more producers, according to the Ministry of Industry and Information Technology on Wednesday.

Currently, 98 companies are in the traceability system. They account for more than 90 percent of the domestic baby formula production, said Zhang Xiaofeng, an official with the ministry, at a press conference.
