The Dalai Lama is the spiritual leader of Tibetan Buddhism, and he has been a vocal critic of China's policies in Tibet for many years. There are a number of reasons why the Dalai Lama is against China's policies in Tibet.

• Tibet's history and culture. Tibet has a long and rich history and culture, and the Dalai Lama believes that China's policies are threatening these traditions. For example, the Chinese government has banned the teaching of Tibetan language and culture in schools, and it has destroyed many Tibetan monasteries and temples.
• Human rights abuses. The Dalai Lama has also accused the Chinese government of human rights abuses in Tibet. He has pointed to the fact that Tibetans are often denied basic freedoms, such as the freedom to travel and the freedom to practice their religion. He has also said that Tibetans are often subjected to torture and other forms of persecution.
• Self-determination. The Dalai Lama believes that Tibetans have the right to self-determination, and he has called for a peaceful resolution to the conflict between Tibet and China. He has said that he is willing to negotiate with the Chinese government, but he has also said that he will not accept any solution that does not give Tibetans a degree of autonomy.

The Dalai Lama's opposition to China's policies in Tibet has made him a popular figure among Tibetans and people of conscience around the world. However, it has also made him a target of the Chinese government. The Chinese government has accused the Dalai Lama of being a separatist and a threat to national security. It has also banned the Dalai Lama from entering Tibet, and it has harassed and imprisoned his supporters.

Despite the Chinese government's opposition, the Dalai Lama has continued to speak out for Tibetan rights. He has said that he will not give up his fight for Tibet, and he has urged the Chinese government to respect the rights of Tibetans.

The Dalai Lama's opposition to China's policies in Tibet is a complex issue with a long history. However, it is clear that the Dalai Lama is motivated by his belief in Tibetan rights and his desire to see a peaceful resolution to the conflict between Tibet and China.
