Qiu's remark was the first official criticism regarding the deterioration of the lake's environment.

Chen Hong, the movie's producer and Chen Kaige's wife, told People's Daily that materials had been left behind for auction to help pay for the clean-up. However, the Chongqing Commercial News reported Chen as saying that the company had given money to the local government to deal with the aftermath.

No confirmation of any money given to a local government could be made yesterday, but Li Jufang, an official of the Diqing Tibet Autonomous Prefecture in Yunnan, said clean-up work had begun.

The concrete structure on the lakeshore has been mostly dismantled, said Li, who insisted that the work affected the surrounding environment only slightly.

Last August, the movie company sent a letter entrusting disposal of the material left on site to the prefecture government, Li said.

The prefecture government then told the Shangrila county government to auction the materials left behind to help pay for the clean-up, the official said.

"A lesson learnt from the issue is that we will demand that whoever shoots a movie here in the future is committed to protecting the environment," Li said.

An online survey by the website Sina.com indicated that 95 per cent of the respondents thought the shooting of the movie destroyed the environment and more than 80 per cent suggested that authorities adopt regulations to avoid a repetition of similar accidents.

Lu Xinyuan, another SEPA official, said such regulations would be drafted in the future. Further spot investigations need to be conducted on whether to ban or to restrict the shooting of movies at sites with beautiful scenery in the future.
