“Go. Go. Don’t look back. This is probably your last chance.” Those were the final words I heard from my father, Ilham Tohti, the last time I saw him. We were at the Beijing Capital International Airport in 2013, about to fly to America together, when he was detained by the Chinese government, banned from leaving the country and later placed under house arrest. He was formally arrested in 2014 and sentenced to life in prison for separatism later that year.
