A big row has broken out over who's to blame for the recent violence in Tibet in Asia.
People have been demonstrating because they don't want Tibet to be ruled by China and several people have died.
China has admitted its forces shot at protestors while trying to break up demonstrations, but claimed rioters killed 19 people in the city of Lhasa.
The Tibetan government said at least 99 people had been killed in the crackdown by Chinese troops.
The Dalai Lama
He was born in Tibet in 1935
He began ruling Tibet at age 15!
He is now exiled in India
He is the spiritual leader of Tibetan Buddhists
Chinese officials have accused the former head of Tibet, the Dalai Lama, of organising the violent protests in an attempt to ruin the Beijing Olympics this summer and promote Tibetan independence.
It says Tibet has always been part of its territory and is continuing to increase security to prevent more protests.
The protests are the biggest challenge to Chinese rule in Tibet in almost 20 years.
Now a leading American politician, Nancy Pelosi, is now calling for an international investigation into the violence.
Ms Pelosi spoke out after talking to the Dalai Lama - who's seen by many Tibetans as their spiritual leader - in India.
