CHINA’S top environmental authority will look into charges that the film production team of “The Promise” damaged the environment around Bigu Lake in Shangri-La County, Yunnan Province, during shooting of the motion picture.
The State Environmental Protection Administration will order its Yunnan subordinate to investigate if the criticism is true, Zhu Xingxiang, head of the administration’s Department for Environmental Impact Assessment, said yesterday.
Zhu said the administration hasn’t received any complaints and reports about the issue, but it is aware of the situation through media reports.
