In Part 2 of our series, we tell the story of an American citizen whose family members have been detained in Chinese re-education camps for Uighurs and members of other Muslim minority groups. We look at what his efforts to free them reveal about the global reach of China’s surveillance. Guest: Paul Mozur, a technology reporter for The New York Times based in Shanghai, spoke with Ferkat Jawdat, a Uighur and American citizen who lives in Virginia.

Background reading:

• Ethnic Uighurs and other Muslim minorities have been sent to camps in vast numbers in what is China’s most sweeping internment operation since the Mao era.
• Chinese officers have attempted to suppress opposition from Uighurs abroad by detaining their relatives.
• The Trump administration has avoided addressing the persecution of the Uighurs during trade talks with China, fearing such a move could jeopardize a deal.
