Sharon Stone's dubious comment is widely criticized in China.

Sharon Stone, 50, suggested last week that the devastating May 12 earthquake in China could have been the result of bad karma over the government's treatment of Tibet.

China's biggest cinema chains now refuse to show her films in their theaters, according to a story in The Hollywood Reporter.

"I'm not happy about the way the Chinese are treating the Tibetans because I don't think anyone should be unkind to anyone else," Stone said Thursday during a Cannes Film Festival red-carpet interview with Hong Kong's Cable Entertainment News.

"And then this earthquake and all this stuff happened, and then I thought, is that karma? When you're not nice that the bad things happen to you?"

During the interview, which has also surfaced on YouTube, Stone also said she cried when she received a letter from the Tibetan Foundation asking her to help quake victims.

"They wanted to go and be helpful, and that made me cry," she said. "It was a big lesson to me that sometimes you have to learn to put your head down and be of service even to people who aren't nice to you."

Ng See-Yuen, founder of the UME Cineplex chain and the chairman of the Federation of Hong Kong Filmmakers, called Stone's comments "inappropriate." He also added that actors should not bring personal politics to comments about a natural disaster that has left five million Chinese homeless, according to the Reporter.
