In statements Nongfu Spring made on its official micro blog over the weekend and on Monday, the company insisted its quality indexes in a number of toxic elements are two to 11 times stricter than the national level.

It accused a Beijing newspaper of "being ignorant" for "singling out several indexes in a whole system to generate conclusions on standards" and making groundless attacks.

The company said the recent attacks on its product quality were set in motion by one of its rivals C'estbon Food and Beverage. The Shenzhen-based company denied having made the accusation.
