Disgraced former swimming champion Sun Yang has vowed to return to elite competition following the end of his long-term doping ban.
Three-time Olympic champion Sun was suspended for four years and three months in February 2020 – reduced from an initial banishment of eight years – for tampering with the doping control process after he and members of his team smashed vials of blood when they questioned the credentials of a doping control officer. Sun has always disputed the circumstances of the incident.
