This month, U.S. companies are scrambling to comply with the Uyghur Forced Labor Prevention Act (UFLPA) that went into effect three weeks ago, ensuring they have no goods in their supply chains made through the forced labor of China’s Muslim Uyghur minority. Here we see an important example of how far efforts have come to document abuses against Uyghurs and other minorities in China’s Xinjiang Uyghur Autonomous Region (XUAR). Documentation efforts including journalistic reporting, investigative work by human rights researchers, and the collection and preservation of witness testimony by NGOs have each played an important role in exposing abuses and linking them to official responsibility in China, laying the foundation for countries like the United States to respond with concrete policy changes such as the UFLPA.
