A more recent parallel, the USA opening the doors to the WTO to China long after the Dalai Lama fled, and the next Dalai Lama imprisoned as a child so the government of China can start selecting the next leaders of Tibetan Buddhism.

NATO intervened to stop the war crimes in the Yugoslav civil war mostly because it was right on the doorstep to Western Europe. Other Arab countries had already intervened years earlier with some people/weapons since the arms embargo had to some extent disproportionately affected the Muslim populations (one common thread with this gulag). This aid /intervention was only possible due to the geographic circumstances of the former Yugoslavia - no outside forces are going to step into China, and stuff like the Opium Wars/forced open doors afterwards means very few in China want foreigners to come in and help.
