Bob Fu is the president and founder of RI partner ChinaAid. He says one mother was teaching her five children at home about literature, maths and religion, when she found herself surrounded by police and arrested. ‘She learned that her husband had reported her faith. You can only imagine the kind of trauma this is causing right inside the family.’ RI’s partners say the Church in China is undergoing the most severe persecution since the Cultural Revolution of the 1960s. They report: ‘The Communist Party is cracking down on the church across the board. It has declared war against Christianity.’ The principal tool in China’s armoury is surveillance technology. According to ChinaAid, the population of 1.3 billion people are under constant surveillance by 2.5 billion face-recognition cameras. ‘Every Chinese citizen is followed by at least two digital face recognition cameras every day, 24 hours a day, combined with big-data technology.’
