China said it was unaware of U.S. allegations that North Korea participated in an attack on Binance, the world’s largest cryptocurrency exchange, in which about $6.3 billion in assets were reportedly stolen. Foreign Ministry spokesperson Mao Ning made the comment at a routine press conference while answering a Yonhap News Agency question. The FBI issued the related allegations on Oct. 31, and Trump said he would communicate with North Korea if the claims were confirmed.
