Perhaps. And if not that, I'm sure there are other forbidden topics there.

Just like in the West.

The difference is that the West pretends to care about free speech and even uses it as an excuse to bomb/sanction/invade other countries.

...Tibet is a province in China and is openly talked about kiddo. Tibet was, for a period of about 40 years, under a brutal monarchy that had institutionalized child sex slavery. The Dalai Lama is a child sex advocate.

Tibet then did a civil war around the time of China's revolution, where the main party of the rebellion which I don't care to look up the name of because Tibetan is mostly nonsense words to me, requested help from the newly freed China. China obliged, with the caveat of Tibet returning to China instead of continuing on as an independent country. Which was greatly preferred during war time at least because, you know, they were spending all their military resources fighting the UK and US backed Tibetan child sex slave government.

After the war, like all provinces Tibet was poor, poorly integrated with the rest of China, and had little access to outside resources... until about the 1990s. Like the rest of China. Now Tibetan culture and language is mandatory for schools in Tibet (like Uyghur in Xinjiang and Mongolian in Inner Mongolia, also there's that weird muslim group in inner mongolia that actually has their own culture and language requirements in schools that I forget. And I mean weird as in, why did they become muslim that far north east, not that they're weird for being Muslim.) and Tibet, like Xinjiang, is seeing a golden age of modernization and resources being poured into it.

Because China realized after the East Tukistan terror attacks from Turkey and the US that you can't have home grown terrorism or dissidence if you just, give people the resources they need to live well and thrive.
