Yang Tengbo, also known as Chris Yang, is a Chinese businessman. He was barred from the United Kingdom in 2023 following accusations that he was using his relationship with Prince Andrew, Duke of York to spy for the Chinese government in the United Kingdom. In 2024, a UK tribunal upheld the decision to bar Yang, acknowledging that while there was 'not an abundance of evidence' in some instances and there could be an 'innocent explanation' for others, it ultimately concluded that there was 'sufficient' material to support MI5's assessment that he posed a security risk.
