There will be 431 Chinese athletes at the Tokyo 2020 Olympic Games , its largest ever overseas contingent, and the youngest will be 14-year-old diver Quan Hongchan. The Zhanjiang, Guangdong native is seen as a medal hope for a country which has long dominated the sport. State news agency Xinhua said China expects to win golds in diving, as well as table tennis, badminton, gymnastics, weightlifting and shooting. IOC to investigate Mao badges worn by China gold medallists Quan and 15-year-old Chen Yuxi will compete in the women’s 10-metre platform. Of the 10 divers picked for Tokyo, Quan is the only one who has not been a world champion. The Olympics will be Quan’s debut international competition. She is 28 years younger than China’s oldest Tokyo Olympian, 52-year-old male equestrian rider Li Zhenqiang. Quan took up diving in 2014, aged seven, and joined the Guangdong provincial team in 2018. She seized her chance at the Olympic trials, no doubt benefiting from the year-long delay because of Covid-19. She won gold as a 13-year-old last October at the 2020 National Diving Championship, which acted as world championships and Tokyo 2020 qualifiers. It was reported at the time that Quan said her motivation for diving was to earn money to help her ill mother afford medical treatment. The teenager won two of the three trials to secure her place in Zhou Jihong’s selection and will join Chen on the highest board in the competition. Chen is also making her Olympic debut, but she won the 2019 world championships. China’s previous 10-metre divers have brought home golds. Ren Qian won the 10m platform at Rio 2016, with Chen Ruolin and Liu Huixia winning the 10m synchronised gold. At London 2012, Chen Ruolin won gold in the 10m platform and the synchronised with Wang Hao. Quan is not the youngest Olympian at the Games. Syrian table tennis player Hend Zaza will be 12 when she competes in Tokyo and is set to be the fifth youngest Olympic athlete of all time. Zaza was 11 when she qualified. British skateboarder Sky Brown is set to be the country’s youngest Summer Olympian at 13 years and 11 days.
