Last month, the U.S. began enforcement of the Uyghur Forced Labor Prevention Act. Signed into law late last year, the UFLPA bans imports of goods made in Xinjiang unless the importer can offer “clear and convincing evidence” that no forced labor was used in their production. Advocates have roundly welcomed the law, but argue that one American law on its own is unlikely to cut into forced labor. Are the law’s investigative mechanisms sufficient to root out forced labor? What is the ultimate goal of such a law, and how might its efficacy be measured?
