The U.S. actress has been featured in ads for the French luxury goods company, which has locations all over the world, since 2005.
"All this earthquake and all this stuff happened, and I thought, is that karma? When you're not nice that the bad things happen to you?" Stone recently said during an interview at the Cannes Film Festival in France, noting she was "unhappy" with the way China was dealing with Tibet.
Nearly 70,000 people are estimated to have been killed in the earthquake in Sichuan province earlier this month.
The Financial Times said that in the wake of widespread criticism regarding Stone's remarks, Dior's Chinese headquarters issued a statement that said: "We absolutely disagree with her hasty comments and we are also deeply sorry about them ... We will never support any opinion that hurts the feelings of the Chinese people."
Dior in Paris declined to comment, the Financial Times said.
