“Growing numbers of Chinese are using the country’s state-backed bankcards to illegally spirit billions of dollars abroad, a Reuters examination has found. This underground money is flowing across the border into the gambling hub of Macau, a former Portuguese colony that like Hong Kong is an autonomous region of China. And the conduit for the cash is the Chinese government-supported payment card network, China UnionPay. Hundreds of neon-lit jewellery, watch and pawn shops are doing a brisk business giving mainland Chinese customers cash by allowing them to use UnionPay cards to make fake purchases – a way of evading China’s strict currency-export controls.”
