Josef Kolmaš, a sinologist, Tibetologist, and Professor of Oriental Studies at the Academy of Sciences of the Czech Republic, writes that it was during the Qing dynasty "that developments took place on the basis of which Tibet came to be considered an organic part of China, both practically and theoretically subject to the Chinese central government." Yet he states that this was a radical change in regards to all previous eras of Sino-Tibetan relations.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Josef Kolmaš  states that Tibet became subject to what government?
the Chinese central government
