Meng Chen

After competitive table tennis resumed following the pandemic, Chen swept the world cup, ITTF pro tour finals, and 2020 All China National Championships.

In May, Chen was selected to represent China in the women's singles and team event at the Tokyo Olympics. Chen won the first leg of the Chinese Olympic Scrimmage but lost to Wang Manyu in the finals of the second leg. Chen again lost to Wang in a closed-door scrimmage in June.

In an interview in July, Chen revealed that she had been in close contact with Ma Lin and Li Xiaoxia regarding mental preparations for the Tokyo Olympics.

At the 2020 Summer Olympics, Chen competed in the women's singles event, winning her semifinals match against Singapore's Yu Mengyu 4–0 and her quarterfinals match against Hong Kong's Doo Hoi Kem 4–2 after trailing 2–0. In the finals match, she defeated compatriot Sun Yingsha 4–2 to win the gold medal. After the match, Chen noted that both she and Sun were both very nervous but played okay, and that Chen's extra experience helped push her over the top. In the women's team event, Chen, along with Sun Yingsha and Wang Manyu, defeated Japan 3–0 in the finals to win the gold medal, continuing China's undefeated streak in the event.

In August 2021, Chen remarked that the level of play at the China National Games was harder than the Olympics. At the National Games of China in September, Chen placed fourth, but her bronze-medal-match opponent Liu Shiwen remarked that Chen was injured and playing far below her normal level.

On 3 August 2024, Chen Meng won the gold medal in the women's singles final at the Paris Olympics, defeating Sun Yingsha 4–2. On 10 August, she helped secure the women's team title alongside her teammates, earning the People's Republic of China its 300th gold medal at the Summer Olympics.
