China Pharmaceutical Group Ltd and several other Chinese makers of vitamin C will face a Nov 5 trial in the US on charges of price-fixing, Bloomberg reported on Tuesday, citing a federal judge.

The decision was declared by US District Judge Brian M. Cogan in New York on Tuesday.

The defendants, including Aland (Jiangsu) Nutraceutical Co, Northeast Pharmaceutical Co and Weisheng Pharmaceutical Co, captured more than 60 percent of the worldwide market for vitamin C by 2001, Cogan said in a September ruling. China's share of vitamin C imports to the US climbed to more than 80 percent in 2002 from 60 percent in 1997.
