Wang Dan, student leader of the June Fourth Tiananmen incident in 1989, clearly advocated for the Tibet issue:
First, civil political dialogue should be initiated between Han and Tibetan peoples, and the CCP should not monopolize representation in dialogue. The Tibetan government-in-exile should initiate dialogue with the Chinese opposition movement;
Second, if Han Chinese are interested in the Tibetan (Tuber) issue, they should first understand the basic content of Tibetan demands. Conversations should start with mutual understanding
The Tibetan side has three documents, systematically and specifically presenting the government-in-exile’s proposals to resolve the Tibetan issue. Whether you agree with these claims or not, at the very least, you need to understand these basic points before you can start a discussion
Wang Dan introduced the specific basic proposals put forward by the Tibetan side in these three documents. For details, please see the link:
