In the video Op-Ed above, three Chinese citizens whose parents disappeared demand their release from China’s “re-education camps.” The government is estimated to have detained over one million people. The goal: to force China’s Uighur ethnic minority to assimilate.

China’s decades-long campaign against the Uighur minority has surged in recent years through the construction of hundreds of detention camps. Even outside of detention centers, millions of Uighurs in China’s Xinjiang region live in a virtual prison. The surveillance state deploys sophisticated technology, including facial recognition tracking, compulsory apps that monitor mobile phones, and even DNA collection.
