Shanghai Zoo accused of failing to publicize the case in a timely manner

State authorities have said that no efforts were spared in attempts to save two giant pandas whose deaths at a Shanghai zoo late last month triggered public anger.

The State Forestry Administration also said on its micro-blogging service that they have good reasons to set up panda conservation and research centers in Shanghai, Beijing and Guangzhou - places which are not traditional habitats for the animals that are deeply loved in China.
