China’s biggest shipping and logistics company Cosco says it is planning to implement a ban on the transport of shark fins. The new policy was announced in a letter to the Hong Kong branch of the U.S. wildlife conservation group WildAid according to the local South China Morning Post. However, Cosco have yet to give an indication as to when the ban would be implemented. Cosco is the world’s fourth largest container operator and joins a host of shipping companies that have said no to transporting shark fin, although some like France’s CMA CGM and Taiwan’s Evergreen Line still carry fins from sharks that are not endangered. The change of heart comes after the discovery earlier this month of 880kg (nearly 2,000 pounds) of endangered hammerhead shark fins, protected under Hong Kong law, on board a Cocso vessel from Panama.
