The International Olympic Committee wants a peaceful end to the violence in Tibet, and opposes an Olympic boycott.

"We believe that the boycott doesn't solve anything," Rogge told reporters on the Caribbean island of St. Kitts. the Associated Press reported. "On the contrary, it is penalizing innocent athletes and it is stopping the organization from something that definitely is worthwhile organizing."

A spokeswoman told Reuters the IOC, "shares the world's desire for a peaceful resolution to the tensions of past days in the Tibetan region of China."

"We hope that calm can return to the region as quickly as possible," spokeswoman Giselle Davies told Reuters.

Violence spilled over from Tibet into neighboring provinces Sunday as Tibetans defied a Chinese government crackdown and the Dalai Lama warned that the area faced "cultural genocide" and appealed to the world for help.

Supporters of the Dalai Lama said 80 people had been killed during the protests in the Tibetan capital, Lhasa, and at least another 72 injured.

The demonstrations came after five days of protests in Lhasa escalated into violence Friday, with Buddhist monks and others torching police cars and shops in the fiercest challenge to Beijing's rule over the region in nearly two decades.

It was the latest negative publicity for China ahead of the Beijing Olympics in August.
