Yes and no. The person who set up the camps, Chen Quanguo, would be the target of any sanctions. He used to lead the Communist Party in Tibet. He brought his Tibetan experience to Xinjiang. The Uighurs are not the only ones living in Xinjiang. The Hui, the Kyrgyz and the Kazakhs live there too. Since the goal is to fight Muslim extremism, the ethnic issue is less important to the Chinese than the religion issue, in the end. People end up in camps because of their religion. It is also due to their ethnic origin, but that aspect is secondary. The religion issue is paramount to the Chinese authorities.
