Hudson Lee, president of Tetra Pak China, said the business was "committed to sustainable development" and was "working together with suppliers, customers, consumers and NGOs" to create a green supply chain.

He added: "We are working hard to support responsible forest management and certification in China, building a convenient platform for consumers to be able to support environmental protection and participate in low-carbon activities by teaming up."

The company said its ultimate goal was to have all supply certified to the highest standard, which it said is currently FSC.
