The quality wars across the Pacific have picked up speed, as Chinese government agencies now say American food is not suitable for consumption.

According to local media, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the Shanghai Entry-Exit Inspection and Quarantine Bureau have identified excessive use of red dye in drinks exported from the United States to China.

AQSIQ says the sugar-free drink in question was produced by Sturm Foods and it did not meet China's relevant health standards. The drinks have been returned to the U.S. manufacturer.

AQSIQ reminds Chinese importers to include China's food safety requirements in their contracts with American manufacturers so as to lower trade risks.
